Abstract: In vague sets the applications of the similarity measure formulas between vague sets are most broad.But we regret that the great majority of the formulas have the faults .In this paper with a method of the piecewise functions we try to mend these formulas,such that the vast majority of the formulas will can continuously use.And a new similarity measure formula between vague sets was presented. This formula more possess the rationality.
