摘要
爱因斯坦场方程有无限坍缩的解存在.当恒星质量超过中子星质量上限时,简并中子压不能抵抗引力坍缩.如果在恒星演化过程有磁应力来支撑引力,超过中子星质量上限的大质量中子星则不致于坍缩成黑洞.
Einstein's field equations have solutions of infinit collapses.When the star mass is over the neutron-star mass,the pressure of degenerative neutron can not react to the gravitative collapse.If the magnetic stress bears up the gravitation in the stellar evolution,the big mass neutron star over the neutron- star mass can not collapse into a black hole.
