摘　　要：在准相对论框架下,以多电子原子精细结构哈密顿的球张量形式为基础,借助不可约张量和角动量耦合理论,导出类铍离子1s22snp(n=2-6)3P态精细结构(包括自旋-轨道相互作用、自旋-其它轨道相互作用和自旋-自旋相互作用)和精细结构参数的解析表达式,并利用我们所开发的程序,对各项进行了具体地计算,计算结果与文献符合地较好.Within the quasi-relativistic framework, based on the tensor expression of the fine-structure Hamihoni- an for many-electron atoms, and with the help of irreducible tensor theory and the angular momentum coupling theory, an analytic formula of the fine-structure energies （ including spin-orbit interaction, spin-other-orbit inter- action and the spin-spin interaction） of the 1s^22snp（n = 2-6）^ 3p state in Be-like ions have been derived. And then, by the virtue of the program code compiled by us, we concretely calculated each term of the fine-structure. The results are in reasonable agreement with the experimental data. Meanwhile, the parameters of fine-structure have been calculated further.
