置反 meaning in Chinese

single displacement reaction

Then we consider the problem as a " conjunction " problem : according to the solutions for wave problem in interface between two conjunctive homogeneous elastic half - spaces as well as the scattering problem of sh - waves by an arbitrary - shape - cavity in homogeneous material , we divide the elastic space with an interface cavity into two parts along the interface , each is elastic half space with an arbitrary - shape - canyon . and then dividing surfaces are loaded with undete rmined antiplane forces , and with some antiplane reacting forces to appear cracks
然后将界面任意形孔洞和孔边裂纹对sh波的散射问题视为“契合”问题：即从两个相互契合的完整弹性半空间的界面波动问题和弹性均匀介质中任意形孔洞对sh波散射的解答出发，沿界面处将含孔洞的弹性空间剖分为两个含有任意形凹陷的弹性半空间，在其剖分表面上加置未知的反平面荷载，在出现裂纹的位置加置反平面反力构造出裂纹。
