Interestingly enough, several of these hydrodynamic adaptations resemble features designed to improve the aerodynamics of high-speed aircraft.
有趣的是，这些流体动力学的适应性变化和人类为了改进高速飞机在空气动力学方面的设计特点十分相似。

Based on the special geologic and hydrodynamicfeatures, the conventional material balance equation is modified.
根据特殊的地质和水动力学特征，对常规物质平衡方程进行了改进。
