采用改进的基于质点速度波形测量的拉格朗日分析方法，研究了率型材料的动态力学性能。

A modified Lagrangian analysis was adopted to study the dynamic mechanical behavior of rate-dependent materials based on particle velocity profile measurement.

A clock tells you what time it is, but you can also say what time it is by seeing how fast the particle is moving because you know it started with some speed.

时钟能告诉你现在的时间,但你也可以通过测量质点速度,来判断当前的时间,因为你知道它的初速度
