Abstract: 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 (1ns) and international experiments driven with multiple-pulse. In the case of longpulse, for three lines of 19.6, 23.2, 23.6nm, 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 resource which is used to diagnose plasma of ICF.
