对于二维碰撞，可以根据车辆的碰撞位置和停止位置，反推计算出车辆碰撞后的分离速度和碰撞前的接触速度。

For collinear collision, the preceding collision velocity and post collision velocity are calculated on the basis of the impact locality and stop locality of collision vehicle.

通过对安装在反应堆压力壳上的多个加速度传感器的信号进行采集，并经过信号预处理、时频变换、神经网络计算等过程，实现对核电站松动件碰撞位置的定位。

The loose part impact positions are located by analyzing signals from accelerometers mounted on the reactor vessel with signal pre processing, time frequency transforms, and neural networks.

The molar volume is being changed a little bit trying to make things collide with each other, they can't occupy the same volume.

摩尔体积发生了很小的改变,如果你试图使气体分子间相互碰撞，他们不能占据同一个位置。
