摘　　要：对推广超流模型（GSM）能级密度公式作了研究，并根据评估的平均中子共振间距D0和分立能级累计数N0拟合出了一组GSM能级密度公式的参数，这组参数已被收入到国际原子能机构（IAEA）推荐输入参数库（RIPL）的起始数据文件.In this work, the Generalized Superfluid Model (GSM) level density formula has been studied. On the basis of the average neutron resonance level spacing D0 and cumulative level number N0 which were evaluated by ourselves, a set of GSM level density parameters has been obtained. These parameters have been included in the initial data file of IAEA's Reference Input Parameter Library (RIPL).
