| 摘 要： | 本文运用广义相对论讨论了满足负指数多方状态方程的流体多层球。经典引力理论与相对论性理论的差别由σ标志。σ是球体中心处的压力与密度之比。通过数值积分得到了n<0的相对论性Emden函数。在-1ed*也增大。

| Abstract: | Based on the general relativistic theory, an investigation on the polytropic fluid spheres with negative index is made. The difference between classical gravitational theory and the relativistic one is measured by a parameter σ, which is the ratio of pressure to density at the center of the sphere. The relativistic Emden functions for n<0 are obtained by numerical integration. For -1ed* increases with the value of σ. |
