摘　　要：目的研究叠加模型中ρ系数与基态g因子之间的关系。方法利用自旋哈密顿理论,采用对角化能量矩阵的方法。结果以YAG:Cr3+晶体为例计算了ρ系数与基态g因子之间的关系。结论ρ系数的取值对基态g因子g∥和g⊥的计算结果基本没有影响,但对Δg的影响较大。Aim The relation between the ground state has been investigated. Methods ρ coefficient in superposition model and the g factor of The spin-Hamihonian theory and the complete diagonalization method are adopted in the calculations. Results The relationship between the p coefficient in superposition model and the g factors of ground state has been calculated by： YAG.. Cr3＋ crystal as example. Conclusion The value of ρ coefficient is almost not influenced by the calculation of g factors of ground state, g// and g⊥ , but exerts a powerful effect on Δg.
