摘　　要：在松散结合的弹性固体和微极多孔立方晶体半空间之间的界面上,研究周期平面波的反射和透射,假定界面性质类似于断层,断层上的牵引力保持连续,但允许产生有限的滑移.用图形给出各种反射波和透射波的振幅比.文中还演绎出某些重要的特殊情况.The problem of reflection and transmission of plane periodic waves incident on the interface between loosely-bonded elastic solid and micropolar porous cubic crystal half spaces was investigated by assuming that the interface behaves like a dislocation which preserves the continuity of traction while allowing a finite amount of slip.Amplitude ratios of various reflected and transmitted waves were depicted graphically.Some special cases of interest also were deduced from the present investigation.
