The influence of the Sun's gravity field on the core nuclear reaction diffusion system is investigated by using the nonequilibrium dynamical theory. It is shown that in the core region extending from the center of the sun to 0.38 solar radius,the space inhomogeneity in the gravity field could lead to instability of the nuclear reaction diffusion system. Post instability gives rise to a new state appearing in the core that has the characteristics of time oscillation. This may change the production rate of solar neutrinos.
