三值逻辑的思想和方法

传统逻辑是二值的，对诸如未来偶然命题使用这种逻辑是无法解决的，这就需要发展起来一种不同于二值逻辑的逻辑，这就是多值逻辑，三值逻辑是其最基本形式。三值逻辑理论沿着不同路线今已得到迅速发展，其应用范围也日益广泛。所有的三值逻辑系统都对二值逻辑的限制有所突破，都在某种意义上显示出“亦此亦彼”的性质，它们之间以及它们与经典二值逻辑之间具有内在的区别和联系，显示了各自独特的思想和构造方法。

The Ideas and Methods of the Three-valued Logic

Traditional logic is binary,and for the future,such as accidental proposition,this logic can not solve,which is different from the need to develop logic of binary logic,which is multi-valued logic,the three-valued logic is the most basic form.Today,three-valued logic theory along the different routes has been developed rapidly,its increasingly wide range of applications.Three-valued logic systems and their relationship with the classical two-valued logic of the distinction between internal and contacts show...
