Abstract
This paper synopsis introduces to Set Pair Analysis (SPA), and fuzzy mathmatics . Studied the SPA involves connexion degree,subjection function and the fuzzy mathmatics involves subjection function etc. the concrete problem, in the same actual problem. This investigative and main characteristics uses two kinds of different theorieses to proceed the research to same actual problem at the same time, can keep the proceeding of the view the comparison well.
Keywords:Set Pair Analysis；fuzzy mathmatics；connexion degree；subjection function
