and its main properties are discussed.The integral representation of the truth degrees of formulas is given
the truth degree modus ponens and truth degree hypothetical syllogism are proved.The concepts of similarity degree and pseudo-metric among formulas are introduced by means of the truth degree.The work of this paper is the base for establishing the framework of approximate reasoning on (3
