We analyse the recently published results from solar neutrino experiments SNO Phase-Ⅲ and SAGE Part-Ⅲ and show their constraints on solar neutrino oscillation parameters,especially for the mixing angle θ12.Through a global analysis using all existing data from SK,SNO,Ga&C1 radiochemical experiments and long base line reactor experiment KamLAND,we obtain the parameters Δm212=7.684+0.212-0.208×10-5 eV2,tan2 θ12-0.440+0.059-0.057.We also find that the discrepancy between the KamLAND and solar neutrino results can be reduced by choosing a small non-zero value for the mixing angle θ13.
