It indicates that stress state affects the close ways of voids and three-dimensional compressive stress state is the best one for healing the internal voids of object.
条件表明应力状态影响空洞的闭合方式，三向压应力是修复空洞缺陷的最佳应力状态。

And then, by using the stress strength interference theory to calculate fracture probability is converted to resolve a onedimensional integral.
当用应力—强度干涉理论计算断裂概率，问题归结为一维积分式的求解。
3
Then, the propagation of one-dimensional strain wave caused by the plate impact is investigated, and the attenuation of stress wave is evaluated.
