reflection ray

A new technique for X-ray stress measurement has been introduced. The formula of calculating stress are inferred according to the theory of X-ray diffraction and the geometry of back-reflection for X-ray area detector, called an imaging plate ( IP).

介绍了一种X射线应力测试新技术，基于X射线衍射原理与影像板平面探测器背反射几何，推导出应力测试基本公式，并列举了应用实例。

In addition, picking zero-offset travel time from two way travel time stacked reflection profile and joint ray tracing inversion with wide-angle reflection and refraction data will obtain more reliable velocity structure.

另外，拾取反射叠加时间剖面零偏移距反射走时和宽角反射并与折射走时进行联合射线追踪反演，可获得更可靠的速度结构。

· The reflection and transmission coefficients of plane elastic and converted waves incident upon an interface between different elastic media are the odd functions of ray parameter p respectively. · The reflection and transmission coefficients of unconverted wave are the even function of ray parameter p.

指出，在不同弹性介质分界面上入射平面弹性波，转换波的反射系数和透射系数是射线参数p的奇函数；非转换波的反射系数和透射系数是射线参数p的偶函数。

In use of ray acoustics and recursion relation, the sound reflection coefficients of arbitrarily many plates have been derived.
