摘 要: 用一般静态各向同性度规研究了中子星的引力能。认为引力场对中子星质量的贡献是由于不变体积元 ,从而使中子星质量的定义得到澄清。 The gravitational field in a neutron star is discussed in the general static iso tropic metric. Different from previous works, the contribution of gravitational field to the ma ss of neutron star is thought to be due to the invariant volume element, and so the definition of mass of neutron star is clerified.
