In short, it is usually enabled only for missiles with a "physical collision effect".

简而言之，它通常被使用在物理碰撞效果。

Experimental results and theoretical work show that the mechanisms of the direct charging and the corona charging are respectively the tip effect and collision effect.

由试验结果和理论分析得到直接荷电法的机理是尖端效应，电晕荷电法的机理为碰撞荷电。

Finally, for the collision effect of cloth with ground, this paper adaptively simplifies the general collision detection and response algorithm, thus makes a smooth, nature-like experimental result.

对于实验模拟的布料与地面的碰撞效果，本文适应性地对碰撞检测和响应算法进行了简化，实现了流畅、接近真实的仿真效果。

The net effect will be to jerk the easy-money football away from Airline Charlie and produce a painful collision between his backside and the hard ground of economic reality.
