摘　　要：通过对D.Kaczorowski等人磁化率倒数—温度曲线的模拟,得到了稀土化合物Ce3Rh2Ga2和Ce3Rh3Si2的晶场系数、分裂能和相应波函数,计算结果与实验吻合较好.计算表明:Kramers离子Ce3+基态简并部分消除得到了双基态.The crystalline electric field （CEF） parameters, the CEF splitting levels and corresponding wave functions of compounds Ce3Rh2Ga2 and Cea Rh3St2 are obtained by means of simulating the temperature dependence of inverse magnetic susceptibility measured by D. Kaczorowski group. The calculated results are in good agreement with the experimental data. The CEF analysis shows thai Kramers ion Cea＋ has a doublet ground state.
