According to coupled wave theory, and from the non-linear differential equation describing characteristics ofreflection hologram, the reflective coefficientofreflection hologram is analyzed.
根据耦合波理论，从描述反射全息的非线性微分方程出发，对反射全息图的振幅反射系数进行了分析。

The results show that the reflectioncoefficient near the wall is about 0. 59, and in the plasma of the first discharge after a gas change, the wall-released isotope amount to 65% .
In case of the loose granular media, the reflectioncoefficient is simplifyed the result obtained is identical with that obtained by seniors from phenomenon theory.
