What kind of ice is the ice in the skating rink?
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. While watching the Olympics, you can also read the wonderful novels related to the Olympics!

A teacher of one word
A teacher of a single word was a Chinese idiom that referred to a teacher who corrected a single word. Some excellent poems became more perfect after someone changed a word. People often called the person who changed the word "the master of one word". For example, in the "Early Plum Blossom" written by Qi Ji in the Tang Dynasty, there was "In the deep snow of the front village, the branches opened last night". Zheng Gu changed "several branches" into "one branch" so that the poem could better reflect the early plum blossom. Zheng Gu was called Qi Ji's "teacher of one word". Jia Dao in the Tang Dynasty was conflicted about "the monk pushed the moon door" or "the monk knocked on the moon door". Han Yu thought that the word "knock" was better, because the combination of movement and stillness could better reflect the quietness and absence of people in the temple. Han Yu was also regarded as Jia Dao's" teacher of one word". In the Song Dynasty, Fan Zhongyan's "Record of Yan Ziling's Ancestral Hall" wrote,"The mountains are green, the river is vast, and the virtue of Mr. is high and the river is long." Li Botai suggested changing "virtue" to "wind". The meaning of "wind" was broader, including not only character but also virtue. It echoed with the previous Yunshan River, and Li Botai also became Fan Zhongyan's "teacher of one word". There were also examples of Li Xiang reading the Spring and Autumn Annals wrongly, but the minor official corrected it, and Li Xiang recognized the minor official as his "one-word master".

Is the Grim Reaper Aizen a charming villain?
In novels related to Death, Aizen was a very charming villain. He had complex motives. On the one hand, he was tired of the setting of fate and the rules of the Corpse Soul World. He longed to surpass the existence of the Spirit King to change the order of the Corpse Soul World. This stemmed from his pursuit of a fair management system, because the system of the Corpse Soul World had problems such as aristocratic privileges. On the other hand, he was powerful but lonely because no one could compare to him. This loneliness prompted him to seek change. His actions were bold and crazy. For example, in order to break through the power of the Death God's boundary, he successfully created an incomplete broken jade, seized the Spirit King fragment from Matsumoto Sanju, and framed Urahara Kisuke to obtain the broken jade and fuse it with a more perfect broken jade. He used the powerful illusion ability of his sword, Ethereal Mirage, to hypnotize many opponents, including the Death God Captain of the 13th Court Guard Team. He also used this ability to control the central 46th room and implement his plan in the entire Corpse Soul World. He seized control of the Void and hypnotized Beilegan Ruissenborn into becoming one of his Ten Blades. He even experimented with the Death God's void-ification, injecting the soul of the Void into the Death God's body to force it into void-ification. His ability was also very powerful. As long as the " Ethereal Mirage " was seen and dispelled, it could instantly hypnotize the opponent. This made him almost invincible in battle. Very few people could break this ability, and even if they did, it would be difficult to defeat him. All of this made Aizen a charming villain. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
