中文摘要：
基于组态相互作用方法，使用Debye模型研究了等离子体屏蔽效应对碳离子结构和不同电荷态离子丰度分布的影响．以类氯碳离子（CV）的1s2 1/2→（1s1/2ns1／2）1（n=2，3，4，5）磁偶极（M1）跃迁为例，详细研究了Debye屏蔽因子对跃迁几率的影响．研究了离子丰度分布随屏蔽因子的变化，结果表明在相同的等离体温度和密度条件下，考虑了屏蔽效应的离子丰度分布整体向低电离度的离子偏移，平均电离度降低．
英文摘要：
The Plasma screening effects on atomic structure of Carbon ions and the population distribution in Carbon plasmas are investigated using Debye model based on the method of configuration interaction. For the magnetic dipole （M1） transitions 1s2 1/2→（1s1/2ns1/2）1（n=2,3,4,5） of C V , the transition rates decrease with the increasing of Debye screening parameter. The population distributions of Carbon ions are studied for a variety of temperature and density. Compared with the population distribution with no screening effects, the population distributions shifts toward the ions with lower ionization degree and the average ionization degree decreases.
