Most of the time, friction between the plates causes them to stick together, and stress increases over time.
大多数时候，板块之间的摩擦力使两者紧紧挤在一起，并随着时间增加，挤压力逐渐增加。
Know what you're going to try and end up with in any given situation, and you'll be able to achieve it far more easily, with far less stress and friction.
并且在给定的任何情况下，要知道你追求的是什么，最终得到什么，这样你将很轻松的得到你想要的，并且不会有太大的压力与阻力。
The result shows that load, seal gap and seal height have influence on the maximum stress while friction coefficient has little influence on it.
分析表明，载荷、密封间隙、橡胶密封筒高度对应力最大值有影响，而摩擦系数影响很小。
