| 摘 要： | 在非均匀球对称的Tolman-Bondi时空中,在Einstein-Cartan理论下,采用M.Gasperini给出的自洽的引力场方程,当考虑自旋与自旋的相互作用时,发现自旋密度对极早期宇宙起支配作用,是引暴涨的根本原因,而且极早期宇宙是以辐射和尘埃为主,同时,由该模型得到一个非零的最小“宇宙半径”和初始密度。

| Abstract: | The Einstein-Cartan theory is employed in inhomogeneous spherically symmetric Tolman-Bondi spacetime. This paper adopts self-consistent gravitational field equations given by M. Gasperini. When matter spin interaction is considered,the energy content of the universe is spin dominated,effective inflation can occur and the universe is radiation and dust dominated at a sufficiently early epoch. At the same time,the model exists anonzero minimal initial "universal radius" and a maximal initial density. |
