摘要

通过等离子体中离子激发-退激发平衡关系,构造一种离子激发组态之间满足的非Boltzmann分布,利用这个分布作为权函数对原子过程速率系数进行平均,构造出一个扩展的碰撞辐射稳态模型.利用该模型计算从低Z到高Z元素等离子体平均离子电荷随电子温度的变化.进而研究非Boltzmann分布对平均电离度和激发组态相对密度的影响.结果表明,它对相对激发组态密度的影响非常显著.

A non-Boltzmann distribution is constructed in terms of ion excitation-deexcitation equilibrium in plasmas, over which the rate coefficients of atomic processes are averaged, and an extended numerical model for charge state distribution of plasmas in collisional radiative steady state is established. The model is used to compute mean ion charge for various plasmas, ranging from low Z to high Z elements, as a function of electron temperature and density. Furthermore, the effects of non-Boltzmann distribution on mean ion charge and ion excited configuration population are investigated. The results show that the ion excited configuration population is evidently affected by the non-Boltzmann distribution.
