摘　　要：Generalizing the idea involved in a previous paper [Commun. Theor. Phys. (Beijing, China) 41 (2004) 685], “quantity in phase space” is introduced. Thus starting from quantum mechanics, with standard criteria, the disappearing of interference in a macroscopic system is explicitly shown. Then the confusions involved in “the Einstein Moon” and “the Schrodinger Cat” are clarified, at least principally.
