1·Stress raiser. A small flaw (internal or surface) or a structural discontinuity at which an applied tensile stress will be amplified and from which cracks may propagate.

一个小裂缝(内部或表面的)或者是结构不连续，在该处施加的拉伸应力将被放大，裂纹会扩展。

2·The stress raiser can be found through the measurement of dynamic magnetic parameters of components so that the diagnosis to components and equipment is implemented timely.

通过时构件动态磁参数的测量，能够发现应力集中区，实现对构件及设备的早期诊断。
