Abstract: Under conditions near the center of the Sun, it shows that 7Be atoms are completely ionized between R=0 to R=0.1217R⊙. The newly calculated 7Be and 8B solar neutrino fluxes are about 4.00×109cm－2·s－1 and 6.18×106cm－2·s－1, while the corresponding predicted values of the standard solar model are 4.80×109cm－2·s－1 and 5.15×106cm－2·s－1,respectively. It will further increase the discrepancy between the observed and the predicted neutrino fluxes in Super Kamiokande neutrino experiment.
