摘要: 给出连通的rectifiable空间是局部序列连通(或局部连通)的刻画, 推广了拓扑群中的相应结果; 利用rectifiable空间$G$中$e$的局部邻域基给出$G$是局部连通(或局部序列连通)的刻画; 证明了若$A$是rectifiable空间$G$中的序列开子集, 那么$H=\langle A\rangle$是$G$的序列开rectifiable子空间.
关键词: rectifiable空间局部连通空间局部序列连通空间对角连通空间对角序列    
Abstract: In this paper, some characterizations of a locally (sequentially) connected rectifiable space $G$ are given under the condition that $G$ is connected, which improves the corresponding result in topological groups; some characterizations of a locally (sequentially) connected rectifiable space $G$ are given from the point of the local neighborhood base of the element e in $G$. It is also proved that if $A$ is a sequentially open subset of a rectifiable space $G$, then $H=\langle A\rangle$ is a sequentially open rectifiable subspace of $G$.
Key words: rectifiable spaces    locally connected spaces    locally sequentially connected spaces    diagonal connected spaces    diagonal sequentially connected spaces
