Narrow-line Seyfert 1 galaxies (NLS1s) are known to be exhibit two distinct features in soft X-ray band. They are large soft X-ray excess and rapid variability. As a model to explain their relatively narrow Balmer line, [4] suggested the slim disk model where the black hole with a moderate mass M~=105-7Msolar accretes nearly at the Eddington rate. In spite of the fact that the emitting region is very close to the black hole, their model was nonrelativistic. In this work, we treat everything relativistically to obtain accurate results which we show in this poster. We also examined the effect of black hole spin on the observed spectrum. We find that it is possible to tell a Kerr black hole from a Schwarzschild black hole when the mass accretion rate is less than 50 times the Eddington rate. .
