摘　　要：导出了类硼离子基态非相对论能量的解析表达式，并利用变分法计算出类硼离子基态的非相对论能量值；利用不可约张量理论导出了类硼离子基态能量相对论修正项（包括相对论质量修正项、单体和双体达尔文修正项、自旋-自旋接触相互作用项）的解析表达式，在此基础上计算了类硼体系（Z=5～8）基态的总能量，计算结果与实验数据符合得较好。The non-relativistic energy levels of the ground states of the Boron-like atoms have been derived analytically and calculated by variational method. With the aid of irreducible tensor theory, an analytic formulism for calculating the relativistic corrections, which include mass correction term, one- and two-body Darwin correction terms and spin - spin contact interaction term, has been established. The total energy levels of the ground states of boron-like atoms from Z = 5 to 8 have been calculated in this way. The results are in good agreement with the experimental data.
