摘要

We analyse the available data of solar neutrino experiments up to the date May 2008,including SK-I,SK-II,SNO phase-I,SNO phase-II and first-generation Ga and C1 experiments.They show great improvement in constraints on solar neutrino oscillation parameters.Together with the new results from long base line reactor experiment KamLAND,the parameters are precisely determined,with la allowed region in △m212 = 7 586+0.212-0.203×10-5 eV2,tan2 θ12=0.457+0.076-0.067
