Depending on the degree of safety to achieve structural control technique like active isolation, passive isolation or conventional seismic design method can be chosen.
依据所要达到的安全程度，可选择采用主动隔震结构控制技术、被动隔震结构控制技术或传统的抗震设计方法。

Earthquake shook the ground at a certain point is the deGREe of strength of seismic intensity.
地震时一定点地面震动强弱的程度叫地震烈度。

This model can consider the effect of the viscosity of rock skeleton and saturation degree on the propagation of the seismic wave.
