请帮我把这几句话翻成英文，谢谢，好答案再加分！

Question

1理论数据要求在实验过程中的摆动是无晃动的，在试验时是很难达到这

一要求。
2实验忽略了绳子与盘子的摩擦力
3忽略了空气阻力
4在硬件尺寸的匹配，盘是否相互平行等方面可能有误差。
5绳子的长度，上下盘地半径和盘的重量
6在上盘绳子与盘接触处装定滑轮，以固定正三角形的悬点。涂抹润滑油

，减小摩擦。
7扭转角度小于5度的设置 。
8三点悬挂式劈木机，转动惯量测试仪，拖拉机三点悬挂装置。

用翻译工具的坚决不给分！

Answer 1

1 the theoretical data requirements in the experimental process the swing is without shaking, during the experiments are difficult to achieve this

One requirement.
2 experimental ignored the string and the plate force of friction
3 ignore the air resistance
4 in hardware size matches, whether the parallel plate etc may have error.
5 the length of rope, on land and the radius of the footwall disc weight
6 in the upper plate rope and pan installed in place diagram to contact fixed is triangular suspended points. Daub lubricant

, reducing friction.
7 reverse Angle is less than 5 degrees Settings.
8 three suspension chopping wood machine, inertia tester, tractor three suspension devices.

Use the translation tools of resolute don't give points!
