【摘要】 <正>We analyze both the early and late time radio and X-ray data of the tidal disruption event Swift J1644+57.The data at early times($\lesssim 5$~days)necessitates separation of the radio and X-ray emission regions,either spatially or in velocity space.This leads us to suggest a two component jet model,in which the inner jet is更多还原
