After analyzing the structure of sentences,Tarski found that, it was impossible to define the truth of the calculus of classes directly,but making use of the structure character of sentential functions could give us the approach to escape the dilemma:Firstly,we could defined the concept of satisfaction in sentential functions by means of recursive method;Then,we could regard sentences as a peculiar form of sentential functions;Finally,with the help of the concept of satisfaction,we could defined successfully the truth of the calculus of classes.

通过分析语句的结构，塔斯基发现很难直接定义出类演算语言的真概念，而语句函项所具有的可递归形成的结构性质可以使我们得到脱离困境的办法：先采用递归方法针对语句函项定义出满足概念，然后把语句作为语句函项的特殊形式，借助于满足概念最终可以得到类演算语言的真概念定义。
