Three temporal logics i.e. first-order predicate calculus, modal logic and reified logic are discussed. 讨论了三种时间逻辑方法:一阶谓词演算,模态逻辑及具体化逻辑。
The elementary first-order temporal logic is a development of modal logic and ordinary temporal logic. 基本的一阶时态逻辑有模态逻辑和时态逻辑的一个发展。
The logical properties of individual variables and individual constants are different, the formulae combining with predications and quantifiers are different whether seen from the standpoint of first-order or modal logic. 个体变元与个体常元的逻辑性质不同,它们与谓词、量词组合的公式在一阶逻辑与模态逻辑中的表现也是不同的。
