water compressibility meaning in Chinese

水的压缩系数
水压缩性

Based on the theory of interaction of fluid - solid , the fem and semi - analytic method are used to analyze the reaction of dam - reservoir subjected to seismic motion , the analysis includes the effect of water compressibility , reflectance of reservoir bottom and water viscosity . the mechanical properties , isolation mechanism and effects of hydraulic air cushions are studied theoretically
从流固耦合理论出发，以有限元分析为主要研究手段，并辅之以半解析法，系统深入研究了水可压缩性、库底库底边界和水体的粘滞性对拱坝地震动水压力及坝体地震反应的影响及其规律性。
Based on the fem model of the dam - reservoir system , the influence of water compressibility to the hydrodynamics is systemically analyzed and researched . it is showed thaf the water compressibility has significant effect to the size and distributing of hydrodynamics on the high dam , and the absorbency of reservoir bottom has a role as a damper on the dam - reservoir system
基于库水体各类边界条件的有限元模型，系统分析了可压缩性对坝体动力响应的影响，表明水可压缩性对高坝动水压力强度和分布具有显著影响，而库底边界条件对大坝的地震反应有抑制作用。
