This paper gives the general kinetics equation as well as the critical shear stress value ( or the critical press gradient value ) when the chain structure breaks down , and the method to get the structure relaxation time in the " structure capture particle " process 给出了电流变响应过程的一般动力学控制方程以及链崩溃时临界的剪切应力值（压力梯度值） ，及俘获粒子过程中有关结构弛豫时间的求法。
