By using the principle of X ray stress measurement, the bearing stress factors of matrix in composites was measured.
结合X射线应力测量原理，建立出基体承载系数的X射线应力测量方法。

Now, most of Chinese bearing factories in dimension measurement for bearing have been mainly dependent on mechanical or optical instruments in sampling inspection way.
目前，我国大多数轴承生产厂家在轴承尺寸检测方面还是依靠机械式、光学式等测量仪器，采用抽检方式进行。

Tracking target by using anti-helicopter mine (AHM) is actually the bearing-only measurement because precision of range detected by passive acoustic measurement cant satisfy the need of tracking.
