ray parameter

· 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。

The Ray-Parameter Method for Acoustic Velocity Measurements of Thin Sediment Layers

测量海底沉积层声速的射线参数法

Therefore the applications of the ray-parameter method to thin layers and the refraction method to hard layers need to be considered in an acoustic velocity measurement system composed of a sound source and a towed hydrophone streamer.

为此，有必要在一个由声源和拖曳水听器阵组成的声速测量系统中设置接射线参数法和折射法测量海底地层声速的处理功能。

The application of the physical parameter method in the solar X-ray telescope is discussed in this paper.
