In this paper, several phase shift methods generally used in accurate test and measurement are discussed. The minor angle circuit is superfacially analyzed mainly.
对精密测试中常用的几种移相方法进行了讨论，主要浅析小角度电路移相方法。
While direction of previous main faults that intersect the maximum principal stress by minor Angle also probably becomes the major migration direction of oil and gas.
与最大主应力小角度相交的先期主要断裂的方向也可能成为油气运移的主要方向。
