After reflection, the average particle velocity near free surface is equal to twice the piston velocity approximately, which agrees with macroscopic phenomena.

激波在自由面反射后，自由表面附近的粒子速度为活塞速度的二倍，这和宏观力学结果相同。

Consequently, at the macroscopic crack branching velocity, the experimental fracture surface energy and the fracture surface roughness; have no single value in such materials.

因此，对这种材料在宏观裂纹分叉速度时，实验断裂表面能及断裂表面韧性没有单一值。

Time evolution of the fluid molecules can be obtained through solving the equation of motion. By averaging the molecule velocity in the system, the simulation gives macroscopic flow description.

薄膜中流体分子的运动规律可由系统运动方程解得，再通过平均得到薄膜液体的宏观特性。

NO So that the more complete answer to the question is that no, we're never going to be able to observe that because of the uncertainty principle it's not possible to observe a velocity that's this slow for a macroscopic object.

所以这个问题的完整答案是，由于不确定性原理,我们不可能测量到这么慢的,宏观物体的速度，希望这个解释。

So, we would actually need a really, really, really tiny velocity here to actually overcome the size of the mass, if we're talking about macroscopic particles, to have a wavelength that's going to be on the order.

是10的负34次方焦耳每秒,所以如果我们谈论的是要一个，宏观粒子有相应数量级的波长的话，我们需要一个非常非常非常小的速度来。
