Solemn statement All large-scale, multi-product comparative evaluation reports of the initial sports evaluation room areIndependent production,Did not cooperate with any brands or businesses.Committed to objectively and neutrally solving doubts for badminton lovers on the way to playing and burning equipment.

What are the performance parameters of badminton?
Badminton is composed of wool, ball head, coil and glue, and the intuitive manifestation can be mainly divided intoFour parameters

  • Flight trajectory:Whether the flying parabola conforms to most people’s hitting habits (whether it will be too blunt or sudden stop).
  • Flight stability:Whether the ball can maintain a unified and stable flight attitude when it stays in the air.
  • Hitting feel:Whether the feedback on the player’s hand is simple and clear when hitting.
  • Hitting resistance:Within an acceptable range, badminton can maintain the ability (duration) of the first three performance experiences.

Evaluation and selection
We have chosen8 brands and 24 badminton modelsMost of them are well-known brands.

From three comprehensive brandsYY, Li Ning, Victory, to well-known ball brandsRSLAnd then to the rookie brand.Ogarin, Kawasaki, WeiconWait; And offline niche brands.BaishengAlso, it was selected as the selection for this evaluation because it was used in many amateur competitions and ball groups around.

The following evaluation optionsAll as consumers,Buy from a reliable source, do not accept samples sent by brands.

Evaluation dimension & evaluation method

The evaluation dimensions of this badminton are:
Performance experience dimension:Flight trajectory, flight stability, hitting feel;

Performance maintenance dimension:Hitting resistance.

Test environment:Location: Guangzhou/Temperature: 16℃/ Humidity: 22/ Ball speed: 77.

Flight path

Adjust the angle of high and long ball with the server, and record the flight trajectory of badminton with a high-speed camera.

Keep the position, angle and strength of the server unchanged, and randomly select 3 balls from each of the 24 balls to test and record them one by one.

After post-processing the material, a visual flight trajectory map is obtained.

Analyze the flight trajectories of several top-class badminton, and get an optimal flight curve by taking the average value.

The curve of each ball is compared with the optimal curve in the first, middle and last stages, and scored according to the deviation. The lower the deviation, the higher the score. (out of 10)

Flight stability

Flight stability includes:wind tunnel testsandActual combat test.

Flight stability score = wind tunnel test score+actual combat test score

We made a simple wind tunnel with air duct+badminton hand glue+carton, which can simulate the stable state of badminton during flight.


We made a simple wind tunnel to simulate the stable state of badminton during flight.

Observe the rotation of the ball head and badminton through wind tunnel simulation. When the center of gravity, balance and roundness of badminton are not good enough, there will be unstable performance.

Through the observation and recording in the actual hitting process, the actual combat score of flight stability is obtained.

Hitting feel

For the hitting feel items that can only be experienced directly by real people, we invited three golfers of different ages to try each ball and score its hitting feel.

Although the ball is different in age and level. But also have their own feelings.

Hitting resistance

Finally, it is the hardest part of our test.

We try to hit 24 kinds of balls high and far, and record the state of the ball every 20 beats, and record the state of the ball in different States, such as starting to shake, starting to slow down, breaking hair, and finally eliminating.Beat countAnd take photos to record the state of the ball.

We try to hit 24 kinds of balls high and far, and record the state of the ball every 20 beats.

Take photos to record the state of the ball at different times of hitting.

Evaluation results

Performance-price ratio formula of initial badminton

Cost performance score = (total performance score * hit resistance score)/market price

Total performance score = flight trajectory score x0.4+ flight stability score x0.4+ hitting feel score x0.2.

The evaluation results of 24 badminton models are as follows:

Purchase instruction

In order to make everyonemake pointed referencesChoose the one that suits you best, and we have made several purchase suggestions for you. Because everyone has different needs and preferences for flying, fighting resistance and cost performance, please adopt it as appropriate.

(95 yuan and goose feather ball with a price of 115 yuan have obvious advantages over duck feather ball in terms of stable performance and durability, so they are better choices for playing in autumn and winter).

(75 yuan’s price, duck and duck’s generous wool film, the performance and beating resistance are above average, and the cost performance is higher)

(The comprehensive performance is relatively ideal, and friends who like it can give it a try.)

Strong Eagle No.20 | Opening Ceremony of Kong Jianping’s Mentor Group of Nanotechnology and the Third Strong Eagle Teacher-Student Tour

On the afternoon of March 4th, the opening ceremony of Kong Jianping’s mentor group and the third Strong Eagle Teacher-Student Tour were successfully held in Zhejiang Nano Technology Co., Ltd.. Teacher Kong Jianping, the chairman of Zhejiang Nanotechnology Co., Ltd., the founder of Rainbow Life Ideological and Political Education Platform, the founder of Qiangying, and the executive vice president of Zhejiang University’s School of Innovation and Entrepreneurship, attended the event. The 19th and 20th sessions of Kong Jianping’s mentor group participated together.

At the beginning of the activity, Mr. Nova, the mentor team of Kong Jianping, introduced the six major sectors: chip, cloud computing, blockchain, AI, application and terminal.New infrastructure of meta-universe industryDevelopment opportunities; Teacher Sunny explained it for everyone from five aspects: story, style, economic dividend, innovation ability and meta-cosmic imagination space.How to do a good job in NFT project blue chip,Compared with the characteristics of Web2, this paper analyzes "why web3.0 is the future" from multiple dimensions, encourages students to publicize and innovate spontaneously, and promotes the healthy positive cycle of NFT projects.

Subsequently, the 19th student Lou Song shared with you.Innovation opportunities of NFT AMMMa Jiahao discussed with everyone.Governance problems and values of DAO creator communityIt is pointed out that DAO creator community has the characteristics of reducing management cost under the inefficient-oriented structure; Shen Yining, a 20-year student, combined his transformation experience from investment bank to content blogger and analyzed.New ideas of traffic growth in Web3 industryZhao Chengcheng introduced how his entrepreneurial project Mind Network was built.Decentralized privacy data lakeGet a place in the industry.

Finally, Mr. Kong Jianping analyzed the top ten pain points of Web3 entrepreneurship for the students, pointing out that the core value of blockchain technology is not decentralization and building a new economic model, but to form a stronger network effect and share liquidity by opening up the user system, thus creating value and income. Mr. Kong suggested that entrepreneurs should be ecological to each other, reject leverage, rely on industry dividends, adhere to the spirit of hard work, and jointly move towards the application Web3 era in the next decade.

During the opening ceremony, Mr. Ruan Junhua introduced the mental journey and value thinking of establishing the Rainbow Life Platform. Teacher Ruan put forward three suggestions for the students: attitude, persistence in long-term, unremitting efforts and courage to pay in following the great cause; Inherit, learn to carry forward the spirit of Zhejiang businessmen, understand the spiritual strength of mentors, and influence and drive more people; Grateful, grateful to the mentor’s educational feelings, grateful to the platform, but also grateful to the opportunities provided by the country and the times.

Later, Ruan Junhua expressed sincere gratitude to Kong Jianping for his re-joining and the strong support of Nanotechnology, and awarded him a letter of appointment as a mentor.

Instructor Kong Jianping issued admission notices to the students in turn and took a group photo.

knowledge gained by study

Ruan junhao

In this study, I deeply realized the rapid development of the digital age and the powerful power of scientific and technological progress. The following are my learning experiences:

As the next generation Internet, the core idea of Web3.0 is to establish a decentralized and open network ecosystem. Compared with Web1.0 and Web2.0, Web3.0 pays more attention to personal privacy protection and data security, and also pays more attention to users’ control and autonomy of data. When studying Web3.0, I deeply understand the importance of decentralization and autonomy, and realize that digital assets and digital identities will become the core content of Web3.0.

AIGC represents the development of digitalization, intelligence, connectivity and security, and is one of the four core technologies in the digital age. AIGC has a wide range of applications, including natural language processing, image recognition, machine learning and so on. When learning AIGC technology, I deeply understand the influence and importance of artificial intelligence on the future. At the same time, I also realize that the development of artificial intelligence needs a lot of data and computing power support, and blockchain technology can provide a safer and more reliable infrastructure for the development of artificial intelligence. For a person who wants to enter the field of web3.0 entrepreneurship, this is a blue ocean full of opportunities.

Finally, I want to thank Mr. Kong and Qiang Ying, who gave me a very good platform and a great learning opportunity.

Pompo

First of all, I am very grateful to the activities organized by Mr. Qiang Ying and Mr. Kong, which made me learn a lot. The content shared in this activity is very diverse and rich, including the infrastructure facilities of the Metauniverse, covering the whole industry chain of chips, cloud computing, blockchain, AI, applications and terminals; There is also the blue-chip market of NFT, the rising logic of mainstream NFT (such as BYAC/Azuki) and some emerging projects. There is also a story about how the DAO organization works to create a science fiction work. In addition, there are some hard-core contents, such as transactions, private data sharing, etc. Although time is limited, I can’t fully understand them, but it also broadens my horizons, gains some new knowledge and enriches my understanding of web3.

Finally, Mr. Kong’s sharing also benefited me in particular, including the development history of web3 industry, the top ten pain points faced by entrepreneurs, the advantages and disadvantages of web2 and web3, public chain ecology, regulatory policies, opportunities for globalization and so on. Teacher Kong suggested that it is very important to choose an industry. No matter what industry you do, you can spend at least 10% of your energy on web3.

zhou weijie

This activity gave me a deeper understanding of the business of the Meta-Universe industry and the Meta-Universe track. During the activity, several students shared their own business projects, and many of the technical terms made me feel the gap between being deeply involved in an industry and understanding an industry in a simple way. Bringing in the sharer’s perspective makes me understand that the understanding of business model and the combing of industrial development logic are far more important than what technology we have mastered. We need to look at business issues from a more macro perspective and use technology to help us deepen our understanding.

In the process of sharing, Mr. Kong put forward several ideas that inspired me deeply. The first is that we should fully grasp the industry dividend, look at the industry, and then deepen the cultivation. The second is that we should think more about how to use new technologies in application scenarios that could not be realized before, instead of iterating over existing things with new technologies. I am very grateful to Qiangying for giving me this opportunity to communicate with outstanding predecessors, and I am also very grateful to Teacher Kong for taking the time to guide us.

Ouyang shengxiong

I am honored to participate in the activities of Mr. Kong’s group, which made me gain a lot. As a small white who is not specialized in the web3 industry, I have learned a lot about web3. For example, the sharing of "Governance Problems and Values of DAO" made me understand a very interesting case, in which 100 people can create a science fiction novel together. Everyone can exert their unique creativity. The introduction of Decentralized Privacy Data Lake made me understand a new form of data privacy protection. In the web1 era, our data is crawled by portals, in the web2 era, the data is held by giant companies, and in the web3 era, we can protect our privacy relatively to a greater extent through encryption services. As a person who hasn’t entered the venue yet, I think I can spend more time paying attention to the progress and dynamics of web3 later. Thank you very much, Mr. Kong.

Shan Zhang

Thank you very much for the third mentor group activity organized by Mr. Kong and Qiangying. In this activity, six guests shared their entrepreneurial experiences and experiences on the track of Web 3.0, covering the current application scene of the Metauniverse, how the financial system supports the development of Web 3.0 projects, the application and innovation of NFT technical support, the exploration of DAO community management mode, the password for realizing traffic growth and the new mode of private data management. Through these sharing, I have a deeper understanding of the Web3.0 industry. I think this decentralized idea can bring some new ideas to finance, social governance and industrial production. During the instructor’s evaluation session, Mr. Kong shared his understanding and experience of Web 3.0, covering a wide range of contents, including organizational forms, relations with the government, opportunities for Chinese entrepreneurs in this track, etc., which broadened my horizons. Dean Ruan also shared his initial intention and feeling of establishing Rainbow Life Platform and Strong Eagle, and sent a message to the students, which made me know how to be grateful and give back to the school and society while growing my own skills.

Wen Chen Yiming

The theme of this activity covers the new infrastructure of the meta-universe industry, the blue-chip road of NFT projects, the innovation opportunities in NFT AMM direction, the governance form of DAO creator community, new ideas for the growth of Web3 industry, decentralized privacy data and teacher Kong’s sharing of the industry. In the process of listening to everyone’s sharing, I learned a new organizational structure model, DAO, which is a decentralized autonomous organization. Members of the organization can freely put forward proposals and organize everyone to vote according to the importance of the proposals. It is an effective way to cooperate with like-minded people all over the world. In this way, the 19th Ma Jiahao seniors completed a book about the meta-universe, which shows that everyone can play their respective strengths in this model. In addition, some students explained the new ideas of traffic growth, including traffic entrance, activation mode, how to retain existing customers and how to let customers promote spontaneously. Finally, Mr. Kong explained to us some pain points in the web3 industry and his understanding. Through this activity, I gained a lot of knowledge about web3. Thanks to Mr. Kong and Qiang Ying for their careful preparation.
