1. Competition scoring method: average.
In the U-pool competition, after a snowboarder skated, five judges gave 8 1, 89, 83, 88 and 84 points respectively, excluding the highest and lowest points. What is the skier's final score?
2. Why do you want to "wipe the floor" desperately in curling competition?
Curling competition is a competition between two teams, each with four people. The two teams take turns pitching, not only to let their curling reach the center of the camp, but also to keep each other's curling away from the center of the circle.
In order to reduce the friction between curling and ice, water droplets will be sprayed evenly on the ice before the game, but the surface of curling track is not as smooth as a mirror, and a slight bump will change the trajectory and speed of curling. Therefore, athletes will change the sliding distance and angle by "wiping the ground" to get better results.
3. Winter Olympics events: classification and assembly.
This year's Beijing Winter Olympics has seven major events, 15 minor events and 109 minor events.
Taking short track speed skating as an example, it is divided into men's events, women's events and mixed events, including 500m, 1000m, 1500m and 2000m, 3000m and 5000m relay events.
4. National flags of different countries: shapes and proportions.
The national flags of all countries in the venue are basically rectangular and look similar, but the ratio of length to width is not exactly the same. For example, the ratio of the national flag of China is 2:3, that of the American flag is 10: 19, and that of Sweden is 5:8.
Moreover, even if they are all national flags with vertical stripes, the proportion of different colors may be different. For example, the width ratio of the blue, white and red colors of the French flag is 30:33:37.
5. Gu Ailing won the championship: rotation angle.
Gu Ailing staged a two-week 1620-degree off-axis rotation when she fell behind her opponent in the first two jumps. The number of turns directly reflects the difficulty of ski jumping, from 1080, 1440 degrees to 1620 degrees, the difficulty is super doubled, and it miraculously wins the championship.
