Staticfracture agent, after all, is one way to break rock and concrete in complicated surroundings and unable blasting condition.
在环境复杂且不能施爆的情况下，用静态破裂剂破裂岩石或混凝土不失为一条捷径。

Based on loading-displacement curve, loading-length of crack expanding is drawn out which can determine crack initiation loading of staticfracture experiments.
结合实验载荷-位移曲线，绘出载荷-裂纹扩展长度曲线，用于静态断裂实验中确定裂纹的起裂载荷。
