摘　　要：本文应用修正后的自洽场离子球模型结合MCDHF框架考虑等离子体屏蔽效应的影响准确计算了类铍等电子序列的跃迁能级及不同电子密度下的能级偏移.结果显示电子的能级偏移对等离子体密度的响应是很敏感的.从当前的计算还可以看出,和的跃迁能级的偏移都是随密度的增加而增加,出现了蓝移现象.MCDHF方法给出的结果与实验和理论值符吻合的都非常好.希望这些结果对分析已有的实验和解释新的实验结果提供参考.Combining MCDHF framework to consider the effects of the plasma shielding effect,the modified self-consistent filed ion sphere model was used to accurately calculate the transition energy and the shift for the different electron density of beryllium isoelectronic sequence. The results show that the atoms of the radiation data to the response of plasma density are very sensitive. From the current calculation,the transition energy levels^2s^21S0→2s2p^3p^01and 2s^21 S0→2s2p^1p^01increased with the increasing density,and the phenomenon of the blue shift appeared. The calculated results obtained by MCDHF method is good agreement between these results and recent theoretical and experimental results. We hope that these results will be useful in analyzing older experiments and planning new ones.
