摘　　要：利用全实加关联(FCPC)方法计算了类锂离子(Z=11～20)激发态1s25p的能级及精细结构劈裂,在此基础上计算了1s22s～1s25p的跃迁能和振子强度.相对论和质量极化效应对能量的修正用微扰论计算,还估算了来自量子电动力学效应的修正.所得到的理论结果与现有的实验数据符合得很好.The transition energies (1s22s 2S1/2～1s25p 2P1/2,3/2) of lithiumlike systems with nuclear charge from Z=11 to 20 are calculated by using a fullcore plus correlation (FCPC) method. The nonrelativistic energies and wave functions are calculated by RayleighRitz's variation method. Relativistic and masspolarization effects on the energies are included as the firstorder perturbation corrections. The quantumelectrodynamics contributions to the transition energy are also evaluated by using effective nuclear charge. The results are in excellent agreement with experimental data in the literature. The dipole oscillator strengths (1s22s～1s25p) of these ions are calculated by using our FCPC wave functions. 
