太阳内部^3He核反应扩散系统的非线性分析

NONLINEAR ANALYSES OF THE CORE 3He NUCLEAR REACTION DIFFUSION SYSTEM 

通过对太阳核心３Ｈｅ核反应扩散系统的非线性分析，说明在对流和扩散效应的影响下，系统形成一种新的超临界空间结构，３Ｈｅ的密度总量因此被增大．进一步分析说明，３Ｈｅ可以浓集在太阳核心某个有限的局域内，从而使３Ｈｅ＋３Ｈｅ反应速率加快以致在这个区域内可以有高的产能率，但中微子产生率不会增加．

Abstract This paper gives the nonlinear analyses of the core 3He nuclear reaction diffusion system. It is shown that the system can be led a sudden change to a new supercritical space structure from the original steady——state after the effects of convection and diffusion are taken into account, and the production rate of 3He changes and the total of its density increases. The 3He may be denser in a limited local region so that the reaction rate of 3He+ 3He is accelerated to have a high energy generation in the region. The understanding for the solar core is also given.
