摘　　要：根据三电子原子非相对论的能级公式导出了类锂离子体系1s23d2D态的非相对论能量的表达式,利用变分方法计算了高离化类锂离子SⅩⅣ-Ga ⅩⅧD的非相对论能量;在此基础上,进一步利用微扰论来计算了类锂离子1s23d2D态的精细结构哈密顿在LSJMJ>表象中的矩阵元,由此得到的SⅩⅣ-Ga ⅩⅧD的精细结构分裂与实验数据符合得较好.The non-relativistic energy expression of the Lithium-like atoms ls^23d^2D states is derived using general expression of non-relativistic energy for atoms with three valence electrons. With the expression, non-relativistic energies and wave functions for Lithium-like atoms S XⅣ-Ga ⅩⅧ are determined by Rayleigh-Ritz method and then the matrix elements of the fine struc-ture Hamiltonian of these atoms in the [LSJMJ〉 representation are calculated with the aid of the first-order perturbation theory. The corresponding results （fine structure intervals） for Lithium like atoms S XⅣ-Ga XⅧ are found in agreement with experimental data in the literature.
