The results show that the reflection coefficient 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% .
While the gas medium is isothermal uniformed, the dissertation calculates the effective absorption coefficient, the Planck-mean absorption coefficient and the wall-incident mean coefficient.
当气体介质等温、均匀时，分别计算气体介质的普朗克平均吸收系数、有效吸收系数和壁面入射平均吸收系数。
