Definition of wiping ice
In curling, the definition of "brush/wipe" is to wipe the ice surface with an ice brush, so as to raise the temperature of the ice surface, melt the ice surface, form a water film on the surface of the ice rink and reduce friction. "
"The heat generated by friction makes the ice surface melt slightly, and then it is frozen and solidified by the lower ice surface. At this time, the ice surface is smoother than before, and the friction coefficient is smaller, so that curling can slide for a longer distance. Whether to brush ice or not, you should further adjust the initial speed with the target position. "
Ice curling game
Curling, also known as "curling", is one of the winter sports. A team throwing stones on the ice. There are four players on each side of the competition. The two sub-stations are at the two ends of the ice rink, aiming at the base circle in the opposite direction, and throwing a oblate stone ball to make it slide into or close to the base circle.
* * * 10 innings per game. Players from both teams pitch twice in each game. The order of the game is as follows: the two sides cross the first baseman, the second baseman, the third baseman and the main players once each, and then hit the ball for the second time. The main players are the most experienced players in a team and undertake the task of commanding the audience.
Each game is judged by the distance between the stones of the two teams and the center of the base camp (also known as the camp). If Team A has two stones closer to the center of the circle than Team B, Team A will get 2 points, and so on. The team that scores more points will win the game in the end.
The order in which the two teams throw stones is determined by drawing lots. Starting from the second game, the winning team in the previous game throws stones first. When throwing, put your feet on the pedal to push the ice. You must let the stone cross the opponent's avant-garde line but not the defender line, otherwise you will be disqualified.
