Based on the teleseismic events which were recorded by shanghai seismic array and using seismic array process technology, the split of PpSmS, P660S and SKS phases are studied. The split parameters of PpSms,P660S and SKS are calculated ,the mantle and crust medium anisotropies under shanghai seismic array region are analyzed briefly according to the difference among PpSmS, P660S and SKS split parameters .
