摘    要:将反应扩散方程推广到存在引力的非等温系统.外场的引入使方程不再有均匀定态解,用该方程分析恒星结构CNO循环的稳定性得到了由引力和温度梯度产生的效应以及一些有趣的结果.

关 键 词:引力  温度梯度  反应扩散方程  GNO循环  稳定性

Abstract:The reaction diffusion equation is generalized in gravitational and nonisothermal system.Because the new equation contains gravitation and temprature gradient,there is not homogeneous stationary state solution of it.The stable condition of CON cycle in reference(4)has been changed into D,K~2-B:(r)>0.This shows it has been strenthened by gravitation. when condition Vg/g=VT/T is satisfied and VT considered constant,the generalized equation has the homogeneous stationary state solution and stability conclusion of the reference(4)is not changed.
Keywords:gravitation  temprature gradient  reaction diffusion equation  CNO cyele  stability
