1. Functions of jogging shoes

First of all, I feel that people are not very concerned about jogging shoes, so the level of understanding is not satisfactory. In order to enhance people's understanding of jogging shoes, we Post a post about this knowledge (due to my limited knowledge, I hope everyone can point out my mistakes and inadequacies, thank you) ADIDAS is a well-known international brand. When it is mentioned, people will naturally think of other brands. The football field produces a mixture of envy and jealousy. The reason why I say this is because people envy its endless football technology and at the same time have to consider that its own share in football is gradually "occupied" by the giants in this football field. And all this seems to cover up ADIDAS itself, which is also very powerful in the field of jogging shoes. Brief introduction to the historical events of ADIDAS jogging shoes: In 1925, ADI DASSLAR developed Tianjing sports shoes with hand-made spikes.

1927 sprint spikes, DRP (West German patent) and debuted at the Olympic Games the following year. In the 1932 Los Angeles Olympics, Chinese athletes wearing AD won the bronze medal in the 100 dash.

At the 1936 Berlin Olympics, Jesse Owens won 4 gold medals and set 5 world records. In the 1952 Helsinki Olympics, AD was the most popular sports brand. Track and field shoes with removable spikes were also put into use at this Olympic Games. Emil Zatopek won 3 gold medals in one week wearing AD shoes, namely 5000, 5000 and 5000. The record of 10,000 and marathon has been maintained to this day.

In 1952, AD produced the first running shoes with replaceable spikes. In 1960, it became the dominant brand at the Rome Olympics. 75% of all track and field athletes wore AD sneakers. Wilma RUDOLPH (Black Gazelle) sprint shoes wore them and won the 100M, 200M, and 4th place at the Rome Olympics. *Vimal, who won three gold medals in the 100M competition, suffered from childhood paralysis when she was a child. No one thought she could still walk.

In 1964, ADIDAS launched the lightest running shoes in history. Tokio64 running shoes weigh only 135K each.

In 1968, ADIDAS was the first company to produce polyurethane multi-studs with cast patterns and provided a one-year warranty for the soles. The first pair of running shoes named Achille was put on the market. In 1972, semi-finished shoes made of shark skin and polyamide were launched. The soles were integrated to develop running shoes that provide better adhesion and friction. In 1976, Edwin Moses won the 400M and 800M gold medals at the Montreal Olympics. Alberto Juantorena, known as the "Fast Horse", is the first athlete to win gold medals in both the 400M and 800M events. They use an adjustable bicycle called the "VARIO system" that was just launched on the market. A cleat system that combines interchangeable plastic and metal pieces.

In 1984, running shoes with embedded "Micro Pacer" computers were launched on the market. Marathon training running shoes won the German "Quality Product" honor from STIFTUNG WARENTEST (an independent German consumer evaluation association).

In the 1992 Barcelona Olympics, track and field athletes wearing AD products won 117 medals. In 1996, ADIDAS designed long-distance running spikes specifically for Atlanta Olympic 10,000M gold medalist Black-Gebre Shirachia.

After that, in 2002, it invested in the development of ADIDAS 1 running shoes. Three years later, in 2005, ADIDAS 1 finally came to the world. After talking about this, I think everyone will have some understanding of AD's jogging shoes. Now I will introduce in detail the technology of AD's jogging shoes, ADIDAS jogging shoes a3: a midsole system composed of independent molded components. , which can play the role of buffering, guiding and promoting during the entire stepping process.

a3 Structure: Structural midsole components provide more stable, longer-lasting cushioning and support than traditional cushioning systems. Depending on the type of sport, stage of movement and athlete's body type, these midsole components also incorporate special cushioning and stability features.

adiPRENE: A shock-absorbing material used to cushion and protect the heel during impact. adiPRENE: An extremely resilient material used to cushion the forefoot and allow the toes to lift off the ground quickly and flexibly.

Agion: An antibacterial upper lining used to prevent bacterial growth and provide odor control. It is very environmentally friendly and durable. It can function as long as the life cycle of the product is long.

E.F.R. (Engineer Forefoot Ride): An outsole structure primarily used in running shoes, consisting of a blown chute inner layer and a full rubber outer layer. Able to provide durability and a more agile, fast pace.

GCS Road: A functional midsole that gradually adapts to ground conditions, improving motion control and slowing the rate of pronation of the foot. GCS Trail: Ground Control System automatically adapts to ground conditions, eliminating the need for your feet to make additional adjustments.

GeoFit: A technology that targets the internal structure of the shoe, placing padding in the right places based on the structural characteristics of the foot to enhance fit and comfort. Gore-Tex XCR: A layered fabric uniquely designed to create an impenetrable barrier against wind and water while maintaining high breathability.

QuickStrike: is an outsole technology that uses a TPU transfer-molded structure to greatly reduce the weight of the shoe, thereby enhancing flexibility. TORSION: A midfoot insert that provides flexibility and torsion between the forefoot and rearfoot and increases stability.

The TORSION System provides mid-foot support while allowing for natural rotation between the ball of the foot and the ball of the foot. TRAXION: Using technology injected directly into the TPU outsole structure, the purpose is to enhance the fit and achieve superior stable landing characteristics.

TRAXION: Using technology directly injected into the TPU outsole structure, the purpose is to enhance the fit and achieve superior stable landing characteristics. The above is the technology of ADIDAS jogging shoes. Although there are 12 technologies, there are only three most commonly used. The value of these three is equivalent to NIKE ZOOM and carbon plate. They are people who are familiar with AD. I think this does not need to be introduced too much. Almost every All AD sports shoes will have one of these three technologies, which shows that their weight is extraordinary. I will introduce other technologies when introducing ADIDAS jogging shoes.

First of all, ADIDAS jogging shoes can be divided into three series: ADI STAR, SUPER NOVA, and RESPONSE. 2. Who knows the development history of Adidas?

The meanings of these two logos have been made very clear by my friends above.

Let me briefly talk about the reasons for its formation. adidas company was registered and established in 1948. In 1949, the first pair of Sanjian shoes was produced, and the Sanjian strip was registered as a trademark. In other words, the three strips trademark currently used in the Performance series of functional shoes is the original trademark of adidasn.

Until the late 1960s and early 1970s, due to the rapid growth of the sporting goods consumer market, it became a watershed for many world sporting goods brands.

At that time, the running shoe industry was booming around the world. According to relevant statistics from the United States, the number of people participating in walking and jogging continued to rise throughout the 1970s. By the end of the 1970s, 25 million to 3,000 Americans insisted on walking. Ten million people, and another 10 million people wear running shoes whether at home or on the street. The rise of running culture has made people's consumption trend more life-oriented. Professional sports equipment can no longer be widely used in daily life. Running shoes with both comfort and practicality have begun to be welcomed by the public. How to bring the comfort of sports shoes into daily life so that ordinary people can be protected like athletes has become a big topic for sports brands. Some people have overcome this problem. For example, Nike took this opportunity to rise rapidly. .

However, adidas, which has more than 40 years of shoemaking history, has not paid attention to this exponentially growing market information. As a result, a large number of adidas shares were later acquired by outsiders. When outside forces became more involved in this old-fashioned and serious German brand, in order to meet the needs of the market, they began to develop sports shoes more suitable for daily life, so the 1972 Clover was born. The birth of the logo. Of course, at the beginning, it still focused on running shoes, which were popular at the time, so the slogan "Strongest, Highest, Farthest" was also full of running-related meanings.

With subsequent development, the advancement of chemical technology and the diversification of manufacturing methods, sports shoes have gradually formed two categories: functional sports shoes and casual retro shoes. In the early 1990s, when the Germans regained control of adidas, the clover brand was already very mature, but they still did not abandon their original three strips. On the one hand, it caters to frequent needs, and on the other hand, it shows that they have not forgotten their roots. Therefore, Clover has been retained and focuses on the retro casual series suitable for daily life, that is, the Originals series. The three strips were reactivated and developed in the direction of professional sports equipment, that is, the Performance series.

The two trademarks represent two different factions of the adidas brand. 3. Pictures witness history and pictures tell history

(1) The founding of New China ushered in a new era of Chinese history.

Since then, China has ended its humiliating history of being invaded and enslaved for more than a hundred years, and has truly become an independent country; (1 point) The Chinese people have since stood up and become the masters of the country. (1 point) (2) The state’s socialist transformation of capitalist industry and commerce (1 point) Redemption (1 point) Completed the task of transforming private ownership of the means of production into socialist public ownership (1 point) (3) Stop using the term “class struggle” With the slogan "As the Guideline", we made the great decision to shift the focus of the party and the country's work to economic construction and implement reform and opening up (1 point) Question analysis: Question (1) mainly tests students' accuracy on the historical significance of the founding of New China Understand and combine the knowledge you have learned to know that the founding of New China ushered in a new era in Chinese history.

Since then, China has ended its humiliating history of being invaded and enslaved for more than a hundred years, and has truly become an independent country; the Chinese people have since stood up and become the masters of the country. Question (2) mainly tests the students' accurate understanding of the three major reforms. According to the question "In 1956, representatives of the industrial and commercial circles reported the good news to Chairman Mao" we can conclude that it was the redemption policy for capitalist industry and commerce during the three major reforms. The socialist transformation carried out marked the transformation of private ownership of the means of production into socialist public ownership.

Question (3) mainly tests students’ accurate understanding of the Third Plenary Session of the Eleventh Central Committee of the Communist Party of China. When solving the problem, it focuses on the analysis and induction of the “turning point with far-reaching significance”. Looking back at the knowledge learned, it can be seen that the Third Plenary Session of the Eleventh Central Committee of the Communist Party of China The Plenary Session of the Central Committee of the Communist Party of China stopped using the slogan "taking class struggle as the key link" and made the great decision to shift the focus of the work of the party and the country to economic construction and implement reform and opening up. .

4. The earliest writings in Chinese history that have evolved to the present include

The evolution trend of writing:

Oracle → Bronze Inscriptions → Seal Script (divided into large seal script and small seal script) → Official Script → Regular Script

The general trend is from complex to simple, and Chinese glyphs and fonts are gradually standardized and stabilized. The evolution process of Chinese character form can be divided into two stages: ancient characters and official regular script. In the ancient writing stage, the sequence of the evolution of Chinese character forms was oracle bone inscriptions, bronze inscriptions, seal scripts, and Qinli. In the official script stage, the evolution sequence of Chinese character forms is official script and regular script.

Official script was popular in the Han Dynasty. The Wei and Jin Dynasties were the transitional stage from official script to regular script. Regular script became popular in the Sui and Tang Dynasties. Official script and regular script are official scripts. In the official regular script stage, auxiliary calligraphy styles - cursive script and running script - also appeared.

Xiaozhuan fixed the number of strokes of each character; official script formed a new stroke system, and the character shape gradually became a flat square;

After the birth of regular script, the glyphs and fonts of Chinese characters became stable. The basic strokes of "horizontal, vertical, left, dot, hold, pick, hook, and fold" were determined, the stroke shape was further standardized, and the number and order of strokes of each character were also fixed; the strokes produced by multi-line writing were The requirement of neat arrangement constrains the changes in glyphs, the length and thickness of the strokes to stretch within the box, and the location and density of the distribution of strokes are also restricted. The glyph structure pays attention to balance and symmetry.

The appearance of regular script finalized the square shape of Chinese characters, and the fonts of Chinese characters matured. For more than a thousand years, regular script has been the standard font of Chinese characters. This is the mainstream of the evolution of Chinese character fonts. The development process of auxiliary fonts cursive and running script is a tributary of the evolution of Chinese character fonts. 5. The evolution of the character "horse" from ancient times to the present (picture)

The evolution of the character "horse" has gone through the evolution of oracle bone inscriptions - seal script - running - cursive - regular script - Song Dynasty History.
