摘　　要：公共知识是群体知识中的一个基本概念。协同攻击难题显示出,在实践中公共知识是一个过强的假定。公共知识的弱化是把公共知识理论应用于实践的必然要求。弱化公共信息概念的提出,澄清了弱公共信念与公共弱信念的实质,弱公共信念是对公共知识的"公共"性质和"知识"性质两个方面同时弱化的结果,而公共弱信念是对公共信念的信念度进行的弱化,是对公共知识的"知识"性质进行弱化的结果。Coordinated attack problem shows that common knowledge is a strong presupposition,so weakening common knowledge and applying it to practice are the necessary choice.Since the common belief is defined,Chinese naming method of weak common belief is proposed for the first time,and nature of almost common belief and weak common belief are clarified.In the paper,it points out that weak common belief is the outcome of comparison between characters of ＂common＂ in common knowledge and of ＂knowledge＂,and that weak common belief is from weakening the degree of common belief,and only from weakening its nature of ＂knowledge＂.
