Can plants really cause cancer？ These three ＂carcinogenic plants＂ can be safely raised as long as they are not eaten.

　　In recent years, I have often met some friends who sent me some pictures of potted plants, saying that I suddenly saw on the Internet that they were carcinogenic plants, but I happened to have them at home. I am very worried. Do you want to throw them away? Some micro-friends even sent links to articles, such as "Don’t leave these 52 kinds of cancer-causing plants at home", "Please stay away from these cancer-causing plants" and "80 kinds of common toxic or cancer-causing plants" … What’s more, it is said that a couple of flower farmers who have been planting flowers for a long time in Foshan City have suffered from nasopharyngeal carcinoma.

　　For a time, flower friends talked about the change of colors, "expelling the culprit of cancer" and "cleaning up the door", which meant that these plants were wiped out. In fact, is this really the case?

　　The statement comes from a paper nearly 30 years ago.

　　It is understood that this statement originated from a paper "Screening of Chinese Herbs and Plants Inducing Early Antigen Expression of Epstein—Barr Virus" by Academician Ceng Yi from Institute of Virology, Chinese Academy of Preventive Sciences. According to the article, "1693 species of plants (Raji cells with EB virus as experimental objects) were screened, and 52 of them were found to have the effect of inducing the early antigen expression of EB virus". And these 52 plants happen to be the "52 carcinogenic plants" transmitted by the Internet.

　　This paper was first published in 1992, almost 30 years later. The news of cancer-causing plants still appears in tabloids, Weibo and friends circle from time to time, and is often mentioned by people. Let the flower growers tread on thin ice, and create many unjust, false and wrong cases of flowers and plants.

　　Epstein-Barr virus is a virus isolated from people with lymphoma. 90%-95% people have been infected by this virus, but most of the time it will not affect human health. Only under the external stimulation, EB virus will suddenly "wake up" and start to replicate in large numbers, which will make the signal pathway controlling normal differentiation and proliferation in cells abnormal, thus causing cancer. Horribly, the activity of EB virus will promote other carcinogenic viruses (such as SV40 virus) to start activities.

　　It is found that the secondary metabolites produced by some plants can activate EB virus, make it wake up and become an active replication state, so these secondary metabolites are called "cancer-promoting" substances. For example, croton oil extracted from croton seeds has a strong ability to induce early antigens of EB virus.

　　However, it can be seen from the above description that plants themselves do not produce EB virus, and even some cancer-promoting substances released into the soil through fallen leaves or roots are only accomplices, not masterminds, in causing cancer. Therefore, the statement that these plants "contain carcinogenic viruses" on the Internet is groundless and a misunderstanding of scientific papers.

　　Plants containing cancer-promoting substances can still be domesticated.

　　Can 52 kinds of plants containing cancer-promoting substances detected by academicians still be raised in their own homes? This is probably what all flower lovers are eager to know.

　　The answer is, of course, yes. These plants, if you don’t eat them and maintain them normally at home, will not cause harm to the human body.

　　If these chemical cancer-promoting substances in plants are taken out and identified, they are just secondary metabolites of plants, and they are a large number of chemical synthetic products with complex structures that are not directly involved in plant growth and development. Plants use these compounds to improve the body’s ability to resist the invasion of the external environment, such as driving away hateful pests, transmitting useful information between plants, dealing with diseases and various unfavorable factors in the surrounding environment, and attracting "matchmakers" or "bodyguards" who help themselves pollinate …

　　Human beings are no strangers to the secondary metabolic "products" of plants, such as rubber, spices, essential oils and so on. The content of these secondary products in plants is not high. Most of the time, they stay quietly in plants and are released only when plants are in danger or their limbs are damaged. Only when these products enter the intruder’s body will they have the effect of poisoning or driving away; For flower growers, only when they enter the human body can they induce cancer.

　　Emphasize that it only induces cancer and promotes cancer, but it is not carcinogenic.

　　Some people may ask, I usually don’t eat potted flowers or move potted flowers, so will the secondary metabolites in these potted flowers float in the room in the form of gas, thus promoting cancer?

　　"It’s all hooliganism to talk about toxicity regardless of dosage". Generally speaking, the secondary substances in plant defense system have large molecular weight and poor volatility. Unlike esters and alkanes which are easy to volatilize in plants, they are mostly water-soluble secondary substances, and almost lose their volatilization ability in plants with high water content. The dose that can be volatilized into indoor air is very small, and they pose a cancer threat to people, even less than smoking a cigarette and breathing automobile exhaust.

　　In the book "Volatile Gases from Plants and Human Health and Safety", the volatile components of Rosa davurica, one of the "52 Carcinogenic Plants", were detected. The results showed that no cancer-promoting components were detected in its volatile components. Therefore, flower friends only need to know the properties of these plants and the characteristics of toxins in their bodies, and they can coexist peacefully with these plants without any burden without touching or eating them.

　　Three so-called "carcinogenic plants"

　　As long as you don’t eat, you can rest assured.

　　Let’s find out three so-called "cancer-causing plants" that are common indoors in northern China for the time being, and here we will break them down one by one.

　　dripping guanyin

　　Drip Guanyin is very suitable for keeping indoors. Staggered leaves, shaped like cattail fans, protrude from the base of brown leaves wrapped in layers, giving off a shiny luster. Drip Guanyin is resistant to shade, and its huge leaf surface can absorb dust and toxic gases in the air. Watered enough water the night before, and got up the next day to observe the leaves. There must be glittering and translucent "water drops" hanging on the tip of the leaves. That is, use toilet paper to absorb the water droplets on the tip of the leaf, and in a short time, a "pearl" will be hung on this part.

　　This is because the dripping Guanyin, which originated from the bottom of the tropical rain forest, can "sweat" like a human being. When it feels hot and humid, and there is too much water in its body, it will excrete the water together with the toxin alkali secreted by pests through its own catheter, and condense it into "water droplets" at the tip of the leaf. This water drop is actually the secret weapon of dripping Guanyin. Small insects that come here for food will be doomed if they drink this honey dew as dew or accidentally touch it. Drinking "honey dew" will make small animals’ mouths red and swollen or suffocate because of heart paralysis; Once the honey dew touches the skin, the skin immediately itches and swells; If the eyes touch the "water drops", it will cause severe conjunctivitis and even blindness … People accidentally touch it, and it is the same symptom. It is also reported that some people saw that the massive stem of Drip Guanyin was very white, a bit like a potato and watery, so they couldn’t help licking it and wanted to taste the juice inside. I didn’t expect this lick to bring disaster-swollen lips, sore throat and numb tongue.

　　In fact, in plants, it is very common that the roots and leaves of plants contain toxins. The dripping Guanyin belongs to Araceae, and most of the plants in this family are poisonous, such as tortoise-back bamboo, evergreen and green radish.

　　crown of thorns

　　Red flowers, rising slowly from the hard and pointed cone thorns, are delicate, charming and graceful. During the Spring Festival, the blooming Rosa davurica will add a lot of spring scenery to the living room, which is also the reason why northerners love Rosa davurica. It is not afraid of drought, waterlogging, shade and sun, and it is very easy to feed.

　　Its vitality is super strong: if you don’t water it for half a year, you won’t get the sun, but you can live in a decent way, and the cute little buds with pink branches will bloom again. Even if you cut a branch and let it lie on the ground, you can grow roots, and green buds will burst out on the branch.

　　Rosa davurica, also known as begonia, is a member of Euphorbia in Euphorbiaceae. Euphorbia plants have a common feature: white milk will be secreted from the wound after the plant is injured. This kind of milk is a diterpenoid compound with special structure, which is toxic. This is also a "sharp weapon" for such plants to protect themselves and prevent pests and diseases from invading during the evolution process. The white milk secreted by the "wound" of Rosa davurica also stimulates human skin and mucous membrane. Eating it by mistake will cause nausea, vomiting, diarrhea and dizziness.

　　iris

　　Iris, which we often say, is not a plant, but a general term for iris plants. Its German Iris, Iris, Iris and Cynthia are all called Iris in principle.

　　Iris plants have bright and beautiful colors. The Latin name iris comes from Greek and is the name of Iriz, the goddess of the rainbow. It can be seen that the colors of iris plants are as colorful as rainbows. It is common to have two or three colors on a flower, which is the eternal darling of horticulture. According to the internet, the rhizome of iris can be used as emetic and cathartic, and can also be used as medicine to treat dizziness and toxic swelling. Eating its flowers, leaves and roots will cause gastrointestinal congestion and severe diarrhea.

　　As can be seen from the above examples, whether these plants cause cancer depends on whether you eat them or want to grow them in flowerpots for viewing. If it is only the latter, you can raise these plants with peace of mind. According to some data, 97% of the 368 kinds of flowers planted at home are beneficial to human health. Of course, we have to emphasize the four basic principles of peaceful coexistence with domestic plants-no matter what flowers are raised at home, don’t import them; Try to avoid zero-distance contact with plant secretions; Wash your hands after handling plants; Open the doors and windows to let the air circulate.

　　Zhongxin. com, Hangzhou, September 29 (Reporter Zhang Yuhuan) On the 29th, the reporter learned from the Zhejiang Meteorological Observatory that according to the latest meteorological data analysis, it is expected that during the National Day holiday this year, Zhejiang Province will be successively affected by typhoon Mina and weak cold air, among which the province will usher in stormy weather from 1 to 2, and the typhoon center may have 14 to 15 winds passing through the sea.

　　The National Day holiday coincides with the growing autumn in Zhejiang. The temperature is generally suitable, but the daily temperature range is large. The average annual temperature in most parts of Zhejiang is 20-22℃, the average precipitation is 15-40 mm, and the average precipitation days are 2-3 days.

　　With the approaching of Typhoon Mina, the 18th this year, the National Day holiday in Zhejiang will also usher in a stronger autumn. On the 29th, the typhoon was strengthened from a tropical storm level to a strong tropical storm level. It is expected to pass the northeast of Taiwan Province Island on the evening of the 30th, and then gradually turn to the north and move towards the north-central coast of Zhejiang.

　　Influenced by Typhoon Mina, Zhejiang Meteorological Observatory predicted that the wind power in the southern part of the East China Sea will start to increase from the 29th, and there will be 11-13 winds in the East China Sea from the 30th to October 1st, and 14-15 winds in the nearby waters where the typhoon center passes, and the wind power in the coastal waters of Zhejiang Province will gradually increase to 10-12, and 13-14 in some areas. There are also 7-9 winds in some inland areas of Zhejiang Province, and there are heavy rains and heavy rains in eastern Zhejiang and parts of northern Zhejiang.

　　From October 3rd to 4th, Zhejiang Province was dominated by cloudy weather, with the highest daily temperature of 32-34℃ in most areas. From October 5th to 7th in the latter part of the holiday, affected by the weak cold air in the north, there was weak precipitation in some areas of Zhejiang Province, and the temperature dropped slowly. The lowest temperature in the morning of October 7th was 16-19℃.

　　The meteorological department reminded that during the National Day holiday, there were heavy rains and heavy rains in eastern Zhejiang and northern Zhejiang, and there were strong winds at sea. Relevant departments should pay attention to preventing the adverse effects of strong winds at sea on island tourism and maritime traffic. From October 3rd to 7th, the weather conditions in Zhejiang Province are generally favorable for leisure travel, but with the influence of cold air moving eastward and southward, we still need to pay attention to the obvious cooling and weak precipitation process.

The exploration that human beings should devote themselves to.

Shi Ruihua Lin Zuoming

The progress of human civilization, as long as there are insurmountable obstacles, will inevitably bring confusion and disaster to human development. There is only one solution: scientific and technological exploration and innovation. Only the ongoing scientific and technological exploration can urge human beings to abandon their prejudices and work together to create a bright future.

In this paper, the author puts forward the following 35 kinds of subversive technologies, which will bring new hope to mankind if they break through. I believe that in the near future, there will be some breakthroughs in scientific and technological innovation, which will put these technologies into use and bring amazing subversive changes to the development of human civilization.

These 35 scientific theories and technologies are:

1. Barrier wave energy engine (special for space shuttle)

Brief introduction: Taking the mm-class magnetic screen as the magnetic energy barrier, the kinetic energy starting from ug-class will have an inverse entropy effect when passing through the screen, which will generate a reaction force with a gain of 800,000 times with the magnetic screen in the form of molecular waves, and promote the movement of the aircraft.

2. Hexagonal plane cohesive energy storage material (battery energy storage)

Brief introduction: Hexahedral crystal balls are synthesized by carbene trimming, which forms a spherical flash-free space and absorbs foreign electrons. When the crystal ball absorbs foreign electrons to saturation state, the stored electrons are output from the crystal surface to the adjacent crystal ball. Adjacent boundary crystal balls also absorb electrons (saturated output) in the form of contrast ratio, forming a step-by-step electron transport-discharge function between crystal balls.

3. Pan-crystalline materials (magnetic and electric superconducting materials at room temperature)

Brief introduction: Using two-dimensional crystal plane materials, the laminated structure materials with nm gaps are made by superposition, so that barrier-free channels are formed between the two-dimensional crystal plane materials, which have no effect resistance on magnetic and electric particles, and pass through the pan-crystalline materials without hindrance at room temperature.

4. Inert film material technology (surface heat-resistant and radiation-resistant materials)

Brief introduction: After the inert gas is heated over-temperature to produce a free suspended state, it is rapidly cooled and polymerized into a mist cloud, and slowly precipitated to form an inert negative-valent olefin film. The vinyl film attached to the surface of an object can make the object have surface heat resistance and radiation resistance.

5. Nano-spinning infrasound generator

Brief introduction: The elastic material with acoustic capacity is made into nm fluff, which is inserted into the wall of the inner tube in the form of um-level equidistant spiral in the synthetic soft metal tube to form a spiral secondary barrier, which generates flexible vibration and releases vibration sound waves during the process of airflow blowing or hair tip discharge. This sound wave is infrasound.

6. Quantum shield technology

Brief introduction: With the quantum cluster screen effect, the space phasor quantum or phasor heteroquantum is equidistantly entangled. Within the angular range of quantum cluster screen, the phasor quantum or phasor heteroquantum entanglement is controlled to be the same cluster quantum, and the same cluster quantum array barrier is formed in the equidistant space, so that the equidistant space becomes a dynamic quantum wall, that is, a quantum shield. Quantum shield technology allows people to cross the sea as if they were on the ground.

7. Neutron-depleted materials

Brief introduction: Quarks after pure neutron energy dissipation are stacked into polycrystalline grains at low temperature, and variable meta-materials are synthesized at room temperature.

8. Three-ground-state gene theory (human gene species)

Brief introduction: This is a standard to confirm the evolution degree of human population based on three basic substances, namely acid, alkali and salt, corresponding to the basic symmetric cryptographic attributes of human genome. There is only one basic substance in the human genome: single-base gene, which is the primary evolutionary human. The human genome corresponds to two basic substances: double-base gene, which belongs to moderately evolved human beings. Three-base gene, which corresponds to all basic substances in human genome, belongs to advanced evolutionary human.

9. 100,000 parts liquid gyroscope

Introduction: Based on the principle that the surface of liquid is absolutely perpendicular to gravity, the mixed cohesive liquid is injected into the spherical inductive container, and the insoluble gas is filled, and the mixed cohesive liquid is pressed to the atomic scale of the container inductance, thus forming the mass-pressure equilibrium atomic 100,000-level head-up ratio.

10. Pure crystalline electron synthesis technology

Introduction: Using non-energy quark pairs as attractors, magnetic particles are induced to hyperpolarize in the eddy magnetic field, resulting in the accumulation of crystalline objects by polar-following particles, forcing the shell particle flow of polar-following particles to change the distance, generating polar electric field flow and becoming an electronic crystalline synthesis.

11. Neutrino communication technology

Brief introduction: Based on the property that neutrinos can cross 98.82% matter effect zone, the second-order neutrinos are selected, and the information content is digitally combined, and then the generator conducts linear directional pacing emission. The receiver uses hydrogenated scintillation screen and light-sensitive receiver to confirm the information content according to the scintillation digits of neutrino touch screen.

12. Cold photon radiation technology

Brief introduction: A semi-spherical fully-enclosed container with the function of directional refraction and reflection and unidirectional light transmission is used as the negative effect zone. After photons with different frequencies enter the effect region, the negative acceleration is generated by the effect region, so that the original velocity of photons reaches the super-original quick-acting energy under the negative acceleration, and photons with internal energy in the polar frequency are generated.

13. Binary dynamic difference laser

Brief introduction: Homogeneous particles with the same charge are focused by low-speed screen focusing and high-speed axial shooting, respectively, at the focal area of a parabolic reflector (reflector), and the energy level is shifted and reversed to release fixed-frequency photons in the form of dynamic difference continuous impact.

14. Isooxygen inactivation theory

Brief introduction: In order to change the dissolved oxygen rate in the blood and glands of the focus, anaerobic and anaerobic virus strains were killed by different oxygen.

15. Manufacturing technology of metal microbubble materials

Brief introduction: Nitrogen is injected into the isothermal alloy material when the alloy material is in isothermal liquid state, and then the alloy material is cooled and solidified with nitrogen rapidly to form intergranular microbubble structure, so as to improve the alloy strength and temperature resistance.

16. Interpretation of resonant frequency building principle formula

Brief introduction: Based on structural secondary point, barrier damping, phasor distribution and cross-section hysteresis entropy, the resonance principle and calculation process are explained by formula method.

17. Particle Universality Theory

Brief introduction: Using particle yoke energy sharing effect, the secondary energy compensation between particles is explained, which constitutes the composition of stable particles and achieves the synthetic effect and basis of targeted innovative substances.

18.Kt-class rotary jet general engine

Brief introduction: The G-level plasma energy is accelerated to incandescent quantum energy by radial acceleration, and the incandescent quantum energy tangential flow is introduced into the yoke jet nozzle by using the hysteresis magnetic screen, which is ejected from the single nozzle in the form of sublight jet, resulting in reactive thrust.

19. Electronic storage technology

Brief introduction: The electron is a 4-quantum internal energy particle, which has the function of point array saturation sorting for electromagnetic signals. The input signals are sorted and stored by electron points according to the input order, and the reserves of each point are planet-level information reserves.

20. Trimmer fusion technology theory (pure fusion bomb theory)

Brief introduction: The cluster point saturation phase transition of condensed pure mercury under the action of resonance energy forms the symmetric polymerization of particles under chord pressure, which releases the chord accumulation variable of quarks and produces the pure fusion energy release effect.

21. The theory of quantum technology of states.

Brief introduction: In the process of entanglement linkage of equal-charge quantum, the potential energy outside the charge naturally tends to cross over with the potential energy, forming self-condensed quantum, which leads to qualitative change in the synthesis of matter and generates self-phase quantum with hyperphysical state change.

22. The theory of crack-guided gyrotron anti-gravity technology

Brief introduction: When the magnetic and electric fields can counteract each other, the magnetic and electric fields will counteract the phasor vibration frequency boundary string and rotate at super high speed, which will force the shellfish particle field flow to have the phenomenon of eddy current delamination cracks. The phase superconducting effect formed by the delamination cracks will form an inverted gravitational screen in steps, which will repel the natural attraction outside the screen.

23. Gas molecular olefin technology

Brief introduction: pure single gas is filled in a clean closed container, and gas molecules are completely purified by plasma heating and static discharge. When the heating temperature causes the gas molecules to generate incandescent clouds, the container is filled with the same pure low-temperature gas as the incandescent clouds again, so that the incandescent clouds quickly coagulate the gas molecules, and they are combined into olefins at an isothermal state.

24. Dry (single) membrane hydrogen production technology

Brief introduction: The conductive vinyl sponge is decomposed into a single-layer reticulated membrane structure, which is put into a metal container filled with conductive purified water, and separated from the container by purified water. One end of the single-layer reticulated membrane is charged with AC electric energy with microwave frequency, so that the single-layer reticulated membrane decomposes water and hydrogen in purified water.

25. Multi-axis shear radar technology (stereo imaging)

Introduction: Based on the principle of all-angle multi-axis wave pattern synthesis, the three-dimensional gain test of intercept point shear is carried out on the test object, and the imaging rate of intercept point echo can reach 99.76% stereo image.

26. Nanocrystalline integrated circuit technology

Brief introduction: On the surface of nano-scale semiconductor single crystal filament, cluster point bridging is used to form components, and multiphase crystal face combined circuit is made, so that electrons form interface saturation transmission and storage, forming unbounded layer integrated circuit.

27. Critical particle clustering technology

Brief introduction: the interface of the particle cluster to be changed is bombarded by sub-particle rays, which makes the particle cluster position form shear infiltration increasing effect and is in a critical state. Under the continuous bombardment, the critical state particle clusters are constantly increasing in shear permeability, which forces the nuclear property to produce transient with the increasing change, and generates material particles with opposite properties to the original material.

28. Quality field technology theory

Brief introduction: Using the steady-state alternating characteristics of gluon force field, nuclear force, magnetic force and gravity are mutually changed by means of loading force field, so as to achieve the unified force field effect of arbitrary transformation and mutual communication of material force field.

29. Negative magnetostatic energy technology (silent propulsion technology with underwater displacement of 100,000-500,000 tons)

Brief introduction: An array-type magneto-resistive tunnel with equal width and one-way opening with mm-class spacing is made of magneto-resistive material. On the wall with mm-class spacing, the magnetic energy in the tunnel is overloaded and damped by an electromagnetic damping rod arranged in the magneto-resistive tunnel, and the overload magnetic energy in the form of pulse is released at the tunnel port, resulting in the reaction thrust of Mg-class (single tunnel) mass magnetic energy.

30. Quantum 13000km molecular resolution physical static and dynamic scanning technology

Brief introduction: Based on the principle of screen-etching phase quantum display, the static and dynamic target objects are tested by screen-scanning, so that the screen-etching phase quantum is linked with the target object quantum, and the linkage information is automatically fed back, and the molecular static and dynamic geometric images of the target object can be displayed through the screen within a distance of 13000km.

31. Jia screen display technology

Introduction: The negative isotope primary color liquid crystal is used as the gamma screen substrate, and the original image can be displayed directly with full-frequency light and color synchronization, and the net screen fidelity rate is 100%.

32. Uranium cocoon nuclear energy technology (micro-nuclear, electric teleportation technology)

Brief introduction: Uranium and diamond matrix are made into a cocoon structure, and positive and negative electrodes are set on the surface and end face of the diamond matrix. The interfacial nuclear energy released by the negative shield of uranium atoms forms a capacitive excitation on the diamond matrix, so that the electrons in the diamond matrix can be squeezed free, and the diamond matrix is output by the end face electrode. After doing work, the uranium cocoon returns to the surface of the diamond crystal matrix to form a loop state.

33. Polarized atoms and their application technology

Brief introduction: Based on the principle that the atoms in the material structure increase or decrease quarks to produce polarization, the asymmetric cross-polarity of polarized quarks is synthesized into overflow particles, which make the internal energy of quarks surface and form cross-polarity energy structure particles, which are applied to various functional and cosmic protection structures.

34. The theory of electronic heteromorphism technology (crystalline, liquid)

Introduction: After the free electrons are input into the left-handed gluon-pair force field, under the action of polarized energy of the force field, the 1/2 alternating process of electrons ends and is in an unbalanced state. Under the continuous action of the force field, the electrons appear pendulum motion, and gradually reduce the pendulum, becoming inert-like electrons, and slowly accumulate near the left-handed gluon pair. Even stacking forms mass crystalline electrons, while prime stacking forms mass liquid electrons.

35. Gamma floating-point holographic imaging technology

Brief introduction: After gamma-ray particles enter the light-transmitting container with the same frequency cleaning effect steam, the same frequency steam in the container produces harmonic steam effect on foreign gamma particles, which makes the foreign gamma particles continuously lengthen their motion frequency in the steam and gradually become reduced-frequency photons, which are suspended in the steam and form a preset holographic image together with the foreign gamma particles entering the steam at the same time, that is, a gamma four-dimensional floating-point holographic image.

For the above 35 kinds of subversive technologies, qualified national scientific research institutions and high-tech enterprises should organize their efforts to study and tackle key problems. Once such technological progress is mature and put into practical use, it will inevitably bring great promotion to the development of human civilization.

Original title: "The exploration that human beings should devote themselves to"

Read the original text

The endurance achievement rate is 102%, and the endurance of MONA M03 in Tucki is measured.

Many people ridicule that it is the next generation of network car, which is not expensive to sell and the configuration is OK. The key is that it has low energy consumption and good economy! In fact, Tucki’s previous car energy consumption control was also good, but the latest MONA heard that it was even worse. We are also very curious about the level of power consumption and endurance achievement rate of this car.

picture

picture

Therefore, we have arranged the endurance test of two scenes simultaneously, one is the high-speed road test, and the other is the urban road test. Besides this endurance test, I have been driving this car back and forth for several days, so I can give you a more comprehensive experience.

First of all, the endurance performance, we still follow the test route of previous tests, located in Nanda trunk line. On the test day, the outdoor temperature was about 32 degrees Celsius, the fast-charging pile was fully charged, the kinetic energy recovery was adjusted to the maximum, the driving mode was adjusted to the energy-saving mode, the air conditioner was adjusted to 24 degrees Celsius to circulate the automatic wind, and the subtotal mileage was cleared, and the tire pressure was maintained at about 240kpa.

Nanda trunk line is a relatively long expressway with a speed limit of 80 km/h. After we are fully charged, we basically run around this road. Except for turning around at both ends and waiting at traffic lights, they are basically driving near the speed limit, but in the end, the average speed is about 60km/h, which can better represent the daily commuting power consumption.

picture

The car we got was an entry-level version of the 515 endurance car, but when the endurance reached 0%, it drove 518km. At this time, the achievement rate exceeded expectations, and it ran for another 9 km until the power was limited. The final result was locked at 527km, and the endurance achievement rate was 102%. The meter showed that the power consumption was 9Wh/100km, which showed the last 100 km, but even if it was calculated according to the electricity, the 51.8-degree electricity ran 50 km.

And on the day of the test, my colleagues in Beijing also took a Tucki, 620 model with a long battery life, and they went directly to the high speed, holding up the live broadcast test at a speed of 120km/h, and finally the power consumption per 100 km was 12.6kWh/100km, which was also very low.

And this 515km version of Tucki, I have experienced five days back and forth, and I have also driven violently, and the power consumption is in the early 14kWh/100km. Therefore, if I drive steadily every day, this endurance performance can be achieved by anyone, which is enough to show that the power consumption of MONA M03 in Tucki is superior to that of the trams on the market at present, regardless of the middle and high speed scenes.

It is also the lowest power consumption among the models we are currently testing.

Some netizens think that the price of this car’s low power consumption is weak power. In fact, to be honest, the control of this car is more advantageous for the same price model, and the feelings of the three driving modes are also different. The economy and comfort modes are similar, but the comfort mode will have a little stronger power in the front and back stages, and the sports mode will be full of power from the beginning.

Kinetic energy recovery can be closed and adjustable in three gears. High kinetic energy recovery will nod a little after releasing the throttle, and it needs to be adapted to the body. It is recommended to open it in the middle and low for daily driving to ensure the comfort of the body and improve the battery life.

MONA in Tucki is relatively easy to drive as a whole, and it is not quite the same as Tucki before. In the past, even if the steering wheel was turned to sport mode, the overall feel was still light, and the medium and large SUVs like that were also very light, while MONA’s steering was obviously much tighter, and the switch damping seemed to be tighter.

Chassis can be regarded as the normal level of this level. The former McPherson rear torsion beam is relatively resilient when passing through some speed bumps at low speed, and it is quite satisfactory for filtering fine vibrations. It will feel less comfortable when encountering relatively large ups and downs, but the overall afterlife is still in line with the tonality of this price.

The layout of the whole car is very simple. There is only one screen in the central control area, and there is no instrument. The overall operation logic is more like the old Tesla, and the operating system interface is relatively simple. Fortunately, most operations can be realized by voice, but this voice does not seem to support multiple voice commands. Only 1-2 commands can be completed at a time, but the recognition accuracy is still ok.

Then the automatic parking recognition rate of this car is average, but as long as most parking spaces are recognized, they can basically be listened to well, and there are 360 images, which can also help you park in reverse, but the rear camera position is low, which may be covered by mud in rainy days. It is best to wipe it in rainy days.

In terms of intelligent driving, this version of my test drive does not have high-speed and intelligent driving in urban areas, but it has a lane intelligent cruise mode, which can drive at the set speed when the lane is set. If you encounter a vehicle in front of you, it will automatically accelerate and decelerate. To a certain extent, it can still better alleviate fatigue, but the power consumption will increase slightly after opening.

In terms of space performance, Tucki is relatively in line with his size, but personally, he feels that the seat cushion angle of the whole vehicle is relatively straight, especially in the back row. Then the spatial performance is basically the performance of an A-class car. The sitting posture of the main driver will be higher than that of the fuel car, and the driver’s seat needs to be adjusted to a slightly larger angle to be more comfortable.

Generally speaking, this car is very cost-effective in the price range of 120,000-150,000. Not only is it low in daily energy consumption, but it is also relatively easy to drive. At the same time, its experience and convenience are relatively advanced. It is perfect for daily urban transportation. I wonder if you are satisfied with the performance of this car?

Ministry of Industry and Information Technology： Since the beginning of this year, the overall production and operation of small and medium-sized enterprises have maintained a recovery trend, and furt

　　Cctv newsIn view of the difficulty in innovation and transformation of small and medium-sized enterprises, the Ministry of Industry and Information Technology and relevant departments recently launched a special campaign to empower small and medium-sized enterprises with scientific and technological achievements and a special campaign to assign brand names to small and medium-sized enterprises with quality standards.

　　On May 19th, the Ministry of Industry and Information Technology held a policy briefing to introduce the two "special actions" and answer reporters’ questions.

　　Xu Xiaolan, Vice Minister of the Ministry of Industry and Information Technology, said that the CPC Central Committee and the State Council attached great importance to the development of small and medium-sized enterprises. General Secretary of the Supreme Leader has repeatedly given important instructions, emphasizing that small and medium-sized enterprises can do great things, and that small and medium-sized enterprises have aura and vitality, demanding that more specialized and innovative enterprises emerge; On September 8, 2022, the General Secretary personally sent a congratulatory letter to the National Conference on the Development of Specialized Small and Medium-sized Enterprises, fully affirmed the important position and role of small and medium-sized enterprises in the new era, put forward ardent expectations for the majority of small and medium-sized enterprises to take the road of specialized and special development, and put forward clear requirements for party committees and governments at all levels to support the development of small and medium-sized enterprises. The Party’s Report to the 20th CPC National Congress proposed to "adhere to two unshakable principles", "support the development of small and medium-sized enterprises" and "support the development of specialized and special new enterprises". Promoting the development of small and medium-sized enterprises is the long-term development strategy of the party and the country.

　　In recent years, faced with the impact of unexpected factors on small and medium-sized enterprises, the Ministry of Industry and Information Technology, together with relevant departments and localities, thoroughly studied and implemented the spirit of a series of important instructions issued by the Supreme Leader General Secretary on promoting the development of small and medium-sized enterprises, resolutely implemented the decision-making arrangements made by the CPC Central Committee in the State Council, and insisted on paying attention to both relief and training, so as to help the vast number of small and medium-sized enterprises develop steadily and healthily.

　　Last year alone, more than 40 policies were issued at the national level to support the development of small and medium-sized enterprises, and more than 270 supporting policy documents were issued at the local level. With the support of various policies to benefit enterprises, the vast number of small and medium-sized enterprises are striving for self-improvement and facing difficulties. In 2022, the operating income and total profit of industrial small and medium-sized enterprises above designated size increased by 5.2% and 1.1% respectively, showing strong resilience and vitality.

　　Since the beginning of this year, the production and operation of small and medium-sized enterprises have generally maintained a recovery trend, and further improvement is expected. According to the survey, in April, 35% of small and medium-sized enterprises thought that their production and operation were in good condition, up 3.2 percentage points from the previous month. Big data monitoring shows that in March, the purchasing and sales indices of SMEs were 51.9% and 51.1% respectively, both of which rose for two consecutive months. Specialized and innovative small and medium-sized enterprises with strong innovation ability performed more brilliantly. In March, the revenue profit rates of "Little Giant" enterprises and specialized and innovative small and medium-sized enterprises were 9.6% and 7.0% respectively, which were 5.5 and 2.9 percentage points higher than those of the regulated small and medium-sized enterprises. From January to April this year, 55.3% of newly listed A-share enterprises were specialized and innovative SMEs, and 67% of newly listed enterprises in science and technology innovation board were specialized and innovative SMEs.

　　At present, small and medium-sized enterprises are still in the recovery period after the epidemic, and the foundation for stabilization and recovery is still not solid. China’s small and medium-sized enterprises and private enterprises are the main bodies of each other, with strong innovation motivation, courage and vitality. They are both the suppliers of innovation achievements and the demanders of innovation elements. There are difficulties in obtaining and transforming scientific and technological achievements. At the same time, the quality management and standardization level need to be strengthened, the brand value needs to be improved, and the supporting level of industrial chain needs to be improved.

　　In view of the new situation and situation faced by the development of small and medium-sized enterprises, in January this year, several measures to help small and medium-sized enterprises to stabilize their growth and adjust their structural strength were promulgated, which clearly put forward "giving wisdom to scientific and technological achievements", "assigning quality standards to brands" and "digitally empowering" small and medium-sized enterprises. The special action of empowering SMEs with scientific and technological achievements, the special action of assigning brand names to SMEs with quality standards, and the "three-fu" special action of digitally empowering SMEs that has been carried out in the early stage are the concrete achievements of studying and implementing the theme education of Socialism with Chinese characteristics Thought of the Supreme Leader in the new era, the "combination boxing" to help improve the innovation ability and core competitiveness of SMEs, and the important measures to promote the high-quality development of SMEs.

Intelligent vehicle management system： improving the intelligent level of enterprise operation

　 　 　 　With the continuous progress of science and technology, the demand for intelligent management in enterprises is increasing. As an efficient management tool, intelligent vehicle management system is gradually becoming an important means to improve the intelligent level of enterprise operation. This paper will discuss how the intelligent vehicle management system can promote the intelligence of enterprise operation.

Comprehensive data collection and analysis

　 　 　 　Intelligent vehicle management system can collect and analyze vehicle operation data in real time by integrating various data sources. This comprehensive data collection provides a scientific basis for enterprise management decision-making, so that managers can better understand the operating conditions.

　 　 　 　For example, a courier company monitors the running status, fuel consumption and customer orders of vehicles in real time through an intelligent management system. Through in-depth analysis of the data, managers can find potential problems in operation in time and make targeted adjustments and optimizations. This comprehensive data analysis has greatly improved the decision-making efficiency of enterprises.

Intelligent scheduling and operational efficiency improvement

　 　 　 　The scheduling function of intelligent vehicle management system can automatically optimize the vehicle scheduling scheme according to real-time data. Compared with traditional manual scheduling, intelligent scheduling is not only more efficient, but also more adaptable to market changes.

　 　 　 　After using the intelligent dispatching system, a transportation company can analyze the traffic situation and order demand in real time, and automatically adjust the distribution and route of vehicles. This intelligent scheduling method improves the operation efficiency, reduces the operation cost, and enables enterprises to better cope with market changes.

Safety management and risk reduction

　 　 　 　Intelligent vehicle management system also plays an important role in safety management. By monitoring the driver’s behavior, the system can identify unsafe driving habits in time, and give an alarm to managers to reduce the risk of accidents.

　 　 　 　A logistics company monitors drivers’ driving behavior through an intelligent monitoring system, and finds that many drivers have problems of speeding and fatigue driving in time. Through systematic warning and training, drivers’ safety awareness has been significantly improved, the accident rate of enterprises has been greatly reduced, and the safety management level has been improved.

Enhance customer experience and brand value

　 　 　 　In enterprise operation, customer experience is very important. By providing real-time order status and vehicle information, the intelligent vehicle management system enhances customers’ trust and improves service quality.

　 　 　 　A shared travel platform provides users with real-time vehicle positioning and estimated arrival time through intelligent management system, which improves customer satisfaction. This transparent information service enhances users’ trust in the enterprise and helps to enhance the brand value of the enterprise.

conclusion

　 　 　 　Intelligent vehicle management system provides strong support for the intelligentization of enterprise operation through comprehensive data collection and analysis, intelligent dispatching and operation efficiency improvement, safety management and risk reduction, and customer experience and brand value improvement. In the future, with the continuous progress of technology, intelligent vehicle management system will play a more important role in promoting the intelligent transformation of enterprises.

Notice of the General Office of novel coronavirus Epidemic Prevention and Control Headquarters on Doing a Good Job in Epidemic Prevention and Control during the National Day Holiday in 2022

Chongqing Pneumonia Finger Office No.49 [2022].

All counties (autonomous counties) leading group for epidemic prevention and control in novel coronavirus, municipal departments and relevant units:

At present, the situation of epidemic prevention and control in our city has generally stabilized, but the epidemic situation in the surrounding areas is still grim, the mobility of personnel during the National Day holiday has increased, and the pressure of "external defense input and internal defense rebound" is still relatively high. In order to thoroughly implement the spirit of the important instructions of the Supreme Leader General Secretary on epidemic prevention and control, implement the relevant deployment requirements of the joint prevention and control mechanism in the State Council, and earnestly do a good job in epidemic prevention and control during the National Day holiday in 2022 in our city, with the consent of the epidemic prevention and control headquarters in novel coronavirus, the relevant matters are hereby notified as follows:

First, it is not necessary to leave Chongqing. Advocate the general public to spend the National Day holiday in the local area, and do not leave Chongqing unless necessary, and do not go to areas with epidemic situation in the past 7 days and land border crossings, especially to high and medium risk areas; If you really need to leave Chongqing, you should take the initiative to report to your unit and village (community) before leaving Chongqing, and hold a negative certificate of nucleic acid detection within 48 hours. When returning to Chongqing, provide negative proof of nucleic acid test within 48 hours, report to the local village (community) or unit, and carry out nucleic acid test (at least once) according to relevant regulations, and implement self-health management measures. Party and government organs at all levels in the city, mass organizations, state-owned enterprises and institutions need to leave Chongqing, and strictly fulfill the examination and approval procedures; Teachers and students of all kinds of schools in the city really need to leave Chongqing, and they need to report to the school.

Second, strictly manage the health of people entering Chongqing. Those who come to Chongqing and return to Chongqing must hold negative proof of nucleic acid test within 48 hours, and traffic ports should increase their strength. For those who come to Chongqing and return to Chongqing in key epidemic areas, they should strictly implement the measures of scanning when entering Chongqing, checking when entering Chongqing, and reporting when entering Chongqing, that is, scanning "entering Chongqing code", checking "two codes and one certificate", conducting a nucleic acid test on the spot and filling in the "two-dimensional code of community report". The community should strengthen investigation, implement classified health management, and urge those who come to Chongqing and return to Chongqing in key epidemic areas to strictly implement prevention and control measures such as centralized isolation, home isolation, and "3-day 2-inspection" to avoid high-risk personnel from leaving the tube and leaking it; Guide people from other areas to come to Chongqing and return to Chongqing to take the initiative to carry out a nucleic acid test within 24 hours.

Third, reduce aggregation activities. Adhere to the principle that it is not necessary to hold it online and offline, and in principle, no large-scale meetings, training, exhibitions, cultural performances and other gathering activities will be arranged in the near future. If it is really necessary to hold it, it should be strictly examined and approved. According to the principle of "who approves, who is responsible" and "who holds, who is responsible", the epidemic prevention and control plan should be formulated, the scale should be controlled as much as possible, and prevention and control measures should be implemented; Participants need to scan the "site code" and check the negative certificate of nucleic acid detection within 48 hours. Advocate citizens not to gather or get together during holidays, reduce dinners and parties, and hold simple weddings and funerals.

Fourth, strengthen the management of key places. Strictly implement the requirements of "code must be set in public places, code must be scanned when citizens enter, and code must be checked by staff", and enter public places to scan "place code" and check "Yukang code". Shangchao, farmers’ markets, catering units, cultural venues, sports venues, entertainment venues, etc. should strictly implement "sweeping when entering" and "checking when entering", and personnel with red code and yellow code of "Yu Kang Code" and pop-up windows are not allowed to enter. Hotels and hotels should strictly check the negative proof of nucleic acid detection within 72 hours. If the "Yukang Code" is a red code or the "itinerary code" is involved in the epidemic-related key areas, immediately report to the community and temporarily control it on the spot; "Yukang Code" is a yellow code and a pop-up window. If you provide negative proof of nucleic acid test within 24 hours or perform nucleic acid test nearby, you can go through the registration formalities (the people who pop up the window for "Entering Chongqing Code" are not subject to this restriction). Civil affairs service institutions such as pension institutions and child welfare institutions should check the negative nucleic acid test certificate of visitors within 48 hours. Scenic spots should strictly implement the requirements of "limit, appointment and peak shift", check the negative proof of nucleic acid test within 72 hours of entering personnel, and scientifically control the flow of people.

Five, strengthen publicity and guidance and personal protection. Health, publicity, cultural tourism and other departments should issue health tips, guide citizens to make reasonable arrangements for travel trips, carefully choose destinations, advocate city tours, short-distance tours and Zhou Bianyou, do personal protection during the whole trip, and try not to go to places where people gather and the space is closed. It is necessary to guide the public to consciously abide by the provisions on epidemic prevention and control, maintain good hygiene habits and lifestyles such as wearing masks, washing hands frequently, using chopsticks, and coughing etiquette. After symptoms such as fever, dry cough, sore throat, decreased sense of smell (taste) and diarrhea appear, they should see a doctor and report it at the first time.

Six, do a good job on duty and emergency preparedness. The epidemic prevention and control command system of all levels and departments in the city should be activated, and a 24-hour duty system should be implemented. The main leading comrades of the party and government are the first responsible persons, and at least one person is on duty during the festival. It is necessary to make emergency preparations such as monitoring and early warning, epidemiological investigation, nucleic acid detection, centralized isolation, community prevention and control, and living security, and scientifically and reasonably arrange personnel to be on standby. Once an epidemic situation is discovered, it should be grasped early and dealt with resolutely and decisively to prevent proliferation and spillover.

Seven, compaction "quartet" responsibility. Relevant departments and units in all districts, counties and cities should earnestly implement the responsibility of "first stop, first question", and properly check traffic entrance, community investigation, prevention and control of key places, closed entry and personal protection, and timely investigate and rectify potential risks. To implement the normalized nucleic acid detection of key populations, all districts in the central city should do a good job in the normalized nucleic acid detection of the general population. It is necessary to effectively coordinate epidemic prevention and control and economic and social development, and resolutely prevent simplification, one size fits all and layers of overweight.
