摘要
本文应用非平衡热力学理论探讨恒星内部氦核反应的稳定性问题,我们得出结论:系统一般是稳定的,只在▽vi<0时可能失稳,而且在忽略扩散和对流的情况下,不一定会对系统的稳定性有影响。
According to the theory of non-equilibrium thcrmodynamics, a nonlinears stochastic equation's solution may describe some characteristics of the non-equilibrium thermodynamic system. From solution(10), We obtain the following condition for the stability of the system.(1) If△·V_i>0, the system of thestellar structure will be stable.(2) If△·V_i<0, the system will be instable(3) If the effects of diffusion and convection are neglected, it is possible that the system will be Still stable. This conclusion is different from that in reference
