我先使这两个碰撞，它们两个相碰，当它们碰撞的时候，我期待速度是一半。
And first I'm going to slam these two onto each other, and so when they collide, I expect the speed to be half.
当然也应该意识到为了使两个触发器碰撞时发出碰撞事件，其中一个必须包含刚体。
Be aware that in order for two Triggers to send out trigger events when they collide, one of them must include a Rigidbody as well.
这些参数之间的变化关系符合直接碰撞导致非晶化模型，即每一个注入离子由于级联碰撞使表面局部的小区域非晶化。
The variation relations between these parameters are found to agree well with direct impact amorphisation model in which each projectileamorphises a logical region by cascade effect.
用等价预测碰撞线代替预测碰撞线，只需要探测视线的角速度，使需要探测的参数减少。文中还提出了外扰动常驻条件下，渐近稳定系统的设计方法。
If predicted collision courses are replaced with equivalent collis'on courses, this method only needs to measure the rotation rate of the Line-of-Sight, therefore, the measured parameters are reduced.
高压开关在合闸时，触头碰撞会产生很大的冲击力，不仅对操动机构造成很大震动、使触头及杆件弯曲变形，而且会造成碰撞后，触头产生弹跳。
It not only makes the operating mechanism shocked hardly and the contactor and poles distorted, but also cause the bounce of contactor after the impact.
