摘　　要：按照Penrose-Hawking的奇点定理,在场源物质无旋、无加速且能量密度满足条件ρ+3p≥0的宇宙模型中一定存在奇点.本文研究了场源物质有旋时的无奇点宇宙模型,获得了几种无奇点的宇宙解.According to Penrose-Hawkings theorem on the singularity of cosmology,the singularity exists in the case when the source havs no rotation or acceleration,and the energy density satisfies the condition ρ＋3p≥0. In this paper we study some singularity-free cosmological models under the conditions that the source has rotation. Some cosmological solutions without singularity are obtained.
