Abstract: A further study of the Sun's interior is very important in understanding the missing solar neutrino problem. In this paper, the space-time correlation of the chemical fluctuation in the nuclear reaction system disturbed by convective motion in the stellar interior is investigated, and the fluctuation behavior driven by 3He in P-PI reaction system of hydrogen burning in the Sun's core is analysed. We show that there is a series of increasing fluctuation waves to be excited in the zone extending from about 0.2R⊙ to 0.4R⊙. These waves are driven by 3He and are excited directly by the disturbance of the convective motion. Because of the disturbing effect, phase velocities of the waves are no longer in direct proportion to their orders and might not be observing proper rules. The fluctuation waves may cause instabilities such as oscillations, etc. occurring in the Sun's interior.
