摘　　要：利用全实加关联的方法计算类锂体系(Z=11~20)1s23s-1s2np(4≤n≤9)偶极跃迁振子强度,分析所得的结果的物理规律,并与现有的实验数据比较,结果符合得很好,实现了对具有较大核电荷数的类锂体系任意高激发态的能量的理论预言.The dipole oscillator strength is the most important spectral property of atomic system. Theoretically, the agreement among the results of the three expressions becomes an indication of the accuracy of the wave function in the whole configuration space and the reliability of the calculated oscillator strengths. The full core plus correlation method is extended to calculate the dipole oscillator strengths for the lithium-like systems （n≤9） from Z=11 to 20. In most cases, it can be shown that the oscillator strengths with three forms agree closely. Compared with the experimental data available in the literature, it appears that the agreement of our oscillator strengths with them is satisfactory. We hope that our predictions will be useful in making higher precision experimental measurements.
