Abstract: As development of equation of state supernova core collapse will reach high density above nuclear density, the general relativitic effects are most important. The density of core collapse is higher in the general relativitic (GR) core than in the Newtonian (NR) case. The higher the density reached the deeper the shock wave digs into the gravitational well and hance the shock wave will be launched with a larger energy. The formation mass point for shock wave is further from core boundary in GR case than in NR case. The disintegration of iron on the way of shock wave to propagate out will be increased. Once the core centre density reaches it maximum, the imner parts of the cross mass point for two velocity distribution in GR case and in NR case (which slight greater than the sonic mass point in NR case). The velocity value in GR case is greater than one in NR case, but the outer parts of the velocity cross point the velocity value is smaller in GR case than one in NR case, when the shock wave reaches the outer parts where the density and velocity is lower in GR case than in NR, which makes it easier for the shock wave to propagate.
