文摘In this paper, we will discuss some properties of biprojection-commutative elements which are relevant to the classification of certain infinite C＊-algebras,, and define an important invariant s（A） of C＊-algebra A as well as give some basic properties with regard to s（A）. Moreover we prove that the invariant s（A） has continuity.
