论文摘要
固定体积和压力作为电离程度的函数的热容量被图形描述为相互温度和电离度的功能。多粒子指数的计算是相同变量的函数。由于它不是恒定的，因此部分离子化的血浆只能是近似聚光流体。同时，启动了一个想法，即Alfvén波可用于用磁性喷嘴加热推进射流中的等离子体。
Heat capacities at fixed volume and pressure as a function of the degree of ionization are graphically depicted as functions of reciprocal temperature and ionization degree. The polytropic index is calculated as a function of the same variables; as it is not constant a partially ionized plasma can be only approximately polytropic fluid. In parallel, it is launched the idea that Alfvén waves can be used to heat the plasma in a propulsion jet with magnetic nozzle.
