针对等离子体状态如何影响特征谱线， 我们研究了辐射碰撞模型（CR）、局域热动平衡模型（LTE）和非局域热动平衡模型等模型计算了所对应的特征谱线强度，定量地给出共振线与共振线强度比、伴线与共振线强度比随等离子体参数的变化关系。研究了等离子体特征谱线的各种展宽机制,重点研究了以斯塔克展宽为主的特征谱线随等离子体状态的变化规律。通过数值求解一维的辐射输运方程，研究了等离子体中的输运对特征谱线强度和线形的改造，通过数值模拟计算出内爆靶丸等离子体温度密度一维时空分布。这些结果对天体物理,聚变物理和国防建设有重要的现实意义。某些惯性约束聚变内爆实验的分析与其它方法的结果基本相符合。此外，作为对该课题研究成果之一，我们从今年起作为一个独立课题参与了国家重点xx工程，我们希望将来能够为国防建设作一些有意义的工作。

In order to study how plasma influence on the spectral line, three plasma models, i.e. collisional-radiative model, local thermodynamic equilibrium and non-local thermodynamic equilibrium model, are established to calculate the intensity of spectral line. The quantitative results are obtained about how the intensity ratios between the resonance lines and its satellite and the resonance lines change sensitively with the plasma temperature and density. The types of spectral-broadening mechanism are carefully studied, especially, how the Stark broadening change with plasma temperature and density are studied. With the calculation of the radiative transportation of one-dimensional equation, we deduced how plasma influence on the intensity and profile of spectral line, and the distribution of electron density and temperature are simulated and discussed. Based on these theoretical investigations of ICF plasmas, a few shots of photon-emission spectrum in ICF(inertial confinement fusion) implosion experiments performed at the China Academy of Engineering Physics are analyzed and studied, and these results are consist with other calculations. Furthermore, as one of our results, we can join one of the important national programs dependently, and hope we will do some valuable works for the national defence in the future.
