为了理解激光等离子体中软X射线发射的非均匀空间结构的起源，研究了等离子体发生相变过程的可能性。通过分析辐射压力及其对温度和密度的依赖关系，研究了等离子体的相图。本文还提出了一种基于粒子模型的计算方法来再现结构的形成。
To understand the origin of the non-uniform spatial structure of the soft x-ray emission in the laser produced plasmas, a possibility for plasmas to have phase transition processes is investigated. Phase diagram of the plasma is investigated through an analysis of the radiation pressure and its dependence on temperature and density. A computational method based on a particle model to reproduce the structure formation is also presented.
