The results show that under static or quasi-static loading the fractal dimension DF is nearly a constant, but under dynamic(impact)loading the DF obviously increases with the loading rates.

结果表明，在静态或准静态加载条件下的断裂面分维数近似为一个常数，但在动态（冲击）加载时，分维数随着加载率的增加而明显增加。

We said, "Let's take, for the simplest case that we can possibly imagine, namely a particle moving in one dimension along the x-axis with a constant acceleration a.

我们说过,"考虑我们可以想象的最简单的情况,即质点在一维空间运动,沿着 x 轴且保持恒定加速度 a
