breaking angle造句

• The study indicate that the surface form has no effect on kl , but has obvious effect on kll , and will affect the breaking angle and mode ; in finite plate , the boundary condition has effect on the sif and the k is bigger than in infinite plate ; the effect of the distance and the angle between cracks are all have obvious effects on the multiple crack interaction , and the interactions between cracks also have obvious effects on the sif , which can be neglect only when the distance is bigger enough
  研究表明：裂面状态对k _的大小没有影响，而对k _的影响却很大，相同应力条件下，裂面状态会影响裂纹的开裂角和开裂方式；有限板的边界对应力强度因子有一定的影响，其k比无限板中的k略大；裂纹间的距离、夹角等因素对裂纹间的干涉效应均有较大影响，裂纹间的干涉效应对应力强度因子的影响非常显著，只有当裂纹间的距离充分大时，干涉效应才可忽略。
