摘要：
We report an observational result for a ULX in NGC253. We find that the spectral evolution is well consistent with the standard behavior. That is, the source satisfies the relation L-disk proportional to T-in(4) as established for black hole binaries. By comparing with black hole binaries, we estimate black hole mass of this ULX as 7M(circle dot).
