存在电场的非等温系统反应扩散方程和CNO循环的稳定性分析

Reaction diffusion equation in a non isothermal system affected by electrical field and stability of CNO cycle

应用非平衡态热力学理论 ,得到了存在电场时非等温系统的反应扩散方程 ,用此方法对恒星内部CNO循环反应进行分析 ,得到了稳定性条件以及恒星结构保持稳定时的最小扰动波数 .结果表明 ,电场的作用对CNO循环反应的稳定性有一定影响 .

The reaction diffusion equation is extended to non isothermal system affected by electrical field. Because the new equation contains the electrical field and temperature gradient, there is no homogeneous stationary state solution of it. In this paper, the stability of CNO cycle is analyzed by the equation.
