计算结果与已有的实验结果符合良好，通过计算进一步给出了下落质量和下落高度对冲击压力峰值的影响。
Further computation shows the rules of the effects of falling mass and falling height on the pressure peak.
由于液压系统的压力值通常是动态的，有时会出现冲击压力，冲击压力峰值会大大高于系统的最高压力值。
For the hydraulic system's pressure always be dynamic, there often appears an impact pressure; the maximum impact pressure is much higher than the maximum system pressure.
结果：水下冲击波物理参数的特征表现为高的峰值压力，正向持续时间较短，冲量较大。
RESULTS:The physical parameters of underwater blast wave were characterized by high peak pressure, short positive duration and great impulse.
