摘要
采用类氢近似公式,以及屏蔽氢模型计算了温度为几个eV的氩等离子体自由-自由吸收系数,其中粒子间相互作用造成的能级下移采用平均离子Debye模型处理,计算结果表明温度为几个eV的氩等离子体的自由-自由吸收系数对不透明度的贡献非常大,较好地计算自由-自由吸收系数对温度为几个eV的氩等离子体不透明度、电子密度和平均离化度的研究都是非常重要的.
The free-free absorption coefficient is calculated by the hydrogen atom and the screened hydrogenic model,where level lowering is considered by the average ionization Debye model.The results show that the free-free absorption contribution to the opacity of argon plasma is very large at the temperature about a few eV.Therefor,the free-free absorption coefficient is very important to research opacity,electron density and average ionization for argon plasma of the temperature about a few eVs.
