摘　　要：本文从近代微分几何及其核心概念微分流形着手,阐释了流形及相关问题与时空结构的关系;用4维几何语言重新剖析时空,建构了时空的微分几何结构.Based on differential geometry and its fundamental concept——differential　manifold,the space-time background is pointed out in this paper,its structure is analyzed and discussed further.At last,the space-time structure is expressed and explained by 4-dimensional geometric language again.

关 键 词：流形 相对论 时空 微分结构
