ice skating great big story

Perhaps it's a personal story within the ice skating community. It could be about a coach who dedicated his or her life to training young skaters and the impact they had on those skaters' lives. Or it could be a story of a group of ice skaters who came together to form a unique team and their journey of competing and bonding together.

I'm not sure exactly which 'ice skating great big story' you mean, but it could include details like a skater's training regime.

Some of the ice in the ice-skating rink was real ice. For example, Jingdezhen's newly opened ice skating rink, the ice skating rink at the Wanda Plaza, and the ice skating rink at the Arctic Ice Pavilion were all real ice skating rinks.

The English words for " skating rink " were " skating rink " or " ice rink." While watching the Olympics, you can also read the wonderful novels related to the Olympics!

Different events had different requirements for the ice surface. In terms of thickness, the ice thickness of short track speed skating was required to be 3 cm to 5 cm, speed skating was required to be 2.5 cm to 3 cm, and figure skating was required to be 6 cm to 7 cm. In terms of temperature, the ice temperature of short track speed skating was-7 ° C to-6 ° C, speed skating was-9 ° C to-5 ° C, and figure skating was-4 ° C to-3 ° C. In addition to these, other ice projects not only had strict requirements on thickness and temperature, but also required the ice surface to be extremely flat, with an error of no more than 0.5 millimeters. For special events such as curling, which had extremely high requirements on the ice surface, each square meter of ice surface had to be able to withstand a weight of 150 kilograms, and the degree of distortion of the ice surface did not exceed 1 mm.

Under normal circumstances, there was ice in the skating rink. The ice skating rink in an international competition like the Winter Olympics was made of real ice. It was an artificially cooled ice rink. The temperature of the ice surface was controlled at-3 - 5 degrees Celsius and the thickness was 4 - 6 centimeters. The ice rink for the official competition would be carefully maintained and the quality of the ice would be good. A certain amount of milk would be added to the ice rink for international competitions to increase the toughness of the ice. In addition, there were also some non-real ice skating rinks, but most of the official skating rinks had real ice.

Well, at the local ice rink, there was an older man who was skating for the first time in years. He was wearing these really old - fashioned skates. He started skating and his skates made the funniest squeaking noise every time he pushed off. People on the rink were looking at him and giggling. He was so focused on skating that he didn't even notice the noise he was making.

Once, I saw a little boy on the ice rink. He was so excited to start skating. But as soon as he pushed off, his feet went in different directions and he ended up doing the splits on the ice. He just sat there for a moment looking so surprised, then he started to laugh at himself. It was really hilarious.

The ice in the skating rink mainly had the following conditions: 1. ** Early situation **: In the early days, ice was made from pure water, but there were problems with the use of pure water ice, such as scratches caused by blade friction, damage to the firmness of the ice surface, and so on. Later, there were ice-skating rinks that added milk to the water. The milk was oily and softer than ice after freezing. It increased the elasticity and crack resistance of the ice surface, reducing scratches and post-maintenance. As the ice-skating rink moved from outdoor to indoor, in order to solve the problems of aesthetics and meet the requirements of the competition, it would also use methods such as removing air bubbles in the ice layer, laying white ice paint, and adding milk to form a white, beautiful, safe and durable indoor ice-skating rink. However, some professional ice-skating rinks no longer used this "milk technology." 2. ** Current situation ** - ** indoor ice skating rink (real ice)**: Generally made of tap water. First, build an ice-skating rink of the required size, install a cooling pipe under the field and connect it to a large refrigerator outside. After injecting tap water, turn on the cooling equipment, and let the tap water cool down to below 0 degrees Celsius to condense into ice cubes, finally forming an ice surface. If the ice surface was used too many times and uneven scratches appeared, there would be specialized personnel to maintain it and add water to form a smooth ice surface. This method of making ice required a high capital cost, and the tickets were relatively expensive. - ** Ice-skating Rink **: The material is high-molecular-weight graphene, which is formed by the condensation of ethene and butadien under the effect of a catalyst. The average molecular weight is greater than 2 million. This material had good comprehensive properties and could work at-269 to +80 ° C for a long time. Its surface was smooth and the ground was flat. It was almost the same as the real ice experience and the cost was low, so most ice rinks would use it. 3. ** Ice rinks in large-scale events (such as the Winter Olympics)**: Advanced technology was used. For example, the 2022 Beijing Winter Olympics used carbon dioxide transcritical direct cooling technology. The ice maker first made a base ice 8 - 10 mm thick, then mixed the white paint with pure water, slowly and evenly sprayed it onto the ice surface, freezing the white paint to form a "milk" ice surface.(This is not really adding milk, but it has a similar effect.) The principle of this technology was similar to that of a refrigerator, but it could accurately control the temperature difference on the ice surface to not exceed 0.5 ° C. With pure water sprayed layer by layer on the ice surface, the ice surface would become stronger. The excess heat during the cooling process could also be used elsewhere, taking into account safety and environmental protection. 4. ** Ice surface treatment during ice filling **: In events such as figure skating, warm water of 40 ° C to 50 ° C is usually poured into the ice arena and frozen. This can melt the surface of the ice and then slowly cool it down to ensure that the ice layer is complete and smooth. Because using ice water would easily affect the fragility of the ice, which was not conducive to the game. Curling, on the other hand, would spray water onto the ice during the game, deliberately creating small particles to increase friction.

As for the ice skating rink painting, on the one hand, the children would use the ice surface as a drawing board to carry out creative painting. For example, the children of Zuncheng Public School in Xiaodian District of Taiyuan City would draw stick figures of ice skating, the Olympic rings, mascots, etc. on the ice skating rink. The different postures and serious appearances showed the children's rich imagination and creativity. On the other hand, there were many ice-skating rink-related paintings that existed in the form of simple strokes, such as ice skating rinks, people skating in the open-air ice skating rink in winter, ice skating rinks in color, ice skating rinks, pairs of ice skating, etc., covering the ice skating rink scene, people in the ice skating rink activities and many other images.
