摘要
研究太阳中心的核反应对太阳中微子问题的解释至关重要 ,也是当前太阳振动测量中最为困难的问题 .通过对p pI核反应链中密度的时间变化研究发现 ,在从 0 0 90 2R⊙ 到0 1 5 0 7R⊙ 的中心区域内 ,3 He的粒子数密度恰好以 5min左右的周期随时间振荡 .这类振荡可以引起太阳核能产生的周期变化 ,从而改变了太阳中微子的产生率 .
The research into the central core nuclear reactions of the Sun plays a vital role in understanding the solar neutrino problem and also is the most difficult problem in the helioseismic measurements. This paper studies the time dependent variation of density in the core p pI nuclear reaction chain. It is very coincidentally discovered that the particle number density of 3 He oscillates with a time period of the order of 5 minute in the core layer extending from about 0.090 2 R ⊙ to 0.150 7 R ⊙ . This oscillation can lead to the similar time variation of energy generation of the core and therefore change the production of the 8 B and 7 Be solar neutrino fluxes.
