对流、核反应和太阳内部振荡

Convection, nuclear reactions and interior oscillations

给出恒星内部对流与核反应耦合的一个动力学模型．借助标准太阳模型，证明了在太阳中心的核反应中，３Ｈｅ的粒子数密度产生和消灭过程均呈振荡状态．在能量产生的峰值区域内，３Ｈｅ的振荡周期大约为５ｍｉｎ，代表着总能量产生的振荡特征．太阳内部的这一特性预期可以说明观察到的中微子流的时间变化．

A model on the coupling of convection with nuclear reactions inside stars is prestnted. With the aid of standard solar models it is shown that particle number density of 3 He oscillates in producing and destroying in the core nuclear reactons. It is found that 3 He oscillates with the time period of order of about 5 min in the region where the energy generation rises up to the maximun. This means the oscillation existing in the total energy production. These new characteristics in the sun may explaine the observed time variations in the solar neutrino fluxes.
