near-surface reflection的意思|示意

Through selecting appropriate curve length of the reflection surface, it can reduce the reflection clutter of the near ground and improve the detection ability of low altitude.

合理选择反射区曲线的长度，可减少近地物反射的杂波，提高低空目标的探测能力。

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。
