Local connections and pathwise connections of topology spaces are introduced by this paper,and the following results are proved:R spaces is pathwise connection,and unit circle which in euclidean plane is connected.In euclidean plane,a set has more than one rational coordinate,we can say the set is connected subset.At the same time,some propositions about local path connected space and some theorems about connectedness of the topological spaces are proved.
