看论坛上有个要钱的关于数学运算表达式的东西，之前写过一个关于数学表达式的单元，现免费发给大家了，当然因为只是临时用才写的，有些粗糙，请原谅。-Have a look forum money on things mathematical expressions, written before the mathematical expression on the cell, is distributed free to the U.S., of course, because it is only a temporary use only written, some rough, please forgive me.

此程序用来求取反射系数。通过左普利兹方程组，知道反射角，给出两层水平地层的横波速度，纵波速度，以及两层的密度，即可来求取反射系数，透射系数。超过临界角时候，使用虚数，并取模作为最终结果。此程序可用来进行地球物理中，反射波，投射波能量、振幅的求取。
