静止角

利用计算机模拟得到的静止角θr和最大稳定角（运动角）θm的值与实验测得的结果符合得很好。

Using computer to imitate this model , the angle of repose θ _r and the maximum angle ( moving angle ) θ _m are agree with the result of experimental perfectly .

颗粒堆积高度对静止角的影响

Effect of height of a sandpile on the angle of repose

几乎每座山的山坡都可以见到巨型滑坡，因为此时的静止角比以往要更小。

Virtually every mountainside would see massive landslides as material sought out a shallower angle of repose .

探讨了在颗粒系统中，沙堆状态与沙堆静止角之间的关系。

The connection between the sands state and the repose angle of sands was concluded in the particle system .

两个相同的定滑轮如下图示，开始时都处于静止，问哪个角速度大？
