摘　　要：　介绍了用国内1ns长脉冲和国外多脉冲驱动的类氖锗的实验数据检验X光激光的理论模拟程序系列的工作。在长脉冲驱动时,对波长19.6,23.2和23.6nm三条激光线,理论模拟与实验数据基本符合。在多个短脉冲驱动时,除了与严重过电离的复合等离子体有关的实验外,理论模拟与实验也基本符合。为今后设计激光聚变等离子体诊断所需类氖锗X光激光光源工作打下了基础。In order to test X-ray laser (XRL) series programs, simulations of some experiments of Ne-like Ge XRL were completed, including domestic experiments driven with long-pulse (Ins) and international experiments driven with multiple-pulse. In the case of long-pulse, for three lines of 19.6, 23.2, 23.6 nm, theoretical results are mainly consistent with experimental data. And in the case of multiple-pulse, theoretical simulations are also consistent with experiments except the experiments with seriously over-ionized recombination plasmas. This work has laid the foundation of later effort to design Ne-like Ge XRL source which is used to diagnose plasma of ICF.
