以类氖－锗离子为例，用逃逸概率方法研究了共振线俘获效应对电子碰撞激发Ｘ光激光增益特性的影响。对波长为１９．６ｎｍ，２３．２ｎｍ和２３．６ｎｍ等三条激光线，讨论了增益特性对增益区宽度ΔＲ和介质速度梯度ｄｖ／ｄｚ的依赖关系
Taking neon - germanium - like ion as an example, the influence of resonance line trapping effect on the gain characteristics of electron collisional excitation X - ray laser was studied by the escape probability method. The dependence of the gain characteristics on the gain region width ΔR and the medium speed gradient dv / dz is discussed for three laser lines with wavelengths of 19.6 nm, 23.2 nm and 23.6 nm
