2、is, under the conditions that every choice set is normal and that the involved t-norms are left-continuous,we use the similarity degree of fuzzy relations, and study the kinds of condition degree of fuzzy choi

3、ce function. The main research is summarized as follows: Firstly, we discuss the property of similarity degree of two fuzzy relations and obtain the relation between the two fuzzy relations property degree on

4、 the basis of the similarity degree of the two fuzzy relation, for example,the relation of reflexity degree and symmetry degree and so on. Then we discuss the two rationality degrees and the two normality degrees and pro

5、ve the four degrees are equal when the revealed preference relation is reflexive, complete and t-torm is Lukasiwicz t-torm,In addition, we obtain relations between the rationality degree of the two functions on the basis

6、 of the similarity degree of the two fuzzy choice functions. Finally,we discuss the connections of WAFRP degree, SAFRT degree, WFCA degree, and SFCA degree of fuzzy choice function, Complement Georgescu’s conclusions, a
