The atomic formula is called atom for short in predicate calculus 在谓词演算中,有时将原子公式简称为原子。
This is not expressible as a first - order predicate calculus property 这就是一个一阶谓词演算不可表述的属性。
Also , first - order predicate calculus isn ' t good enough anyway 同时,从各方面来说,一阶谓词演算都不是足够好。
This kind of assertion seems to require special language extensions and has led people to suggest introducing first - order predicate calculus 这种情况下的断言似乎就需要实现特定的语言扩展,于是一些人建议引入一阶谓词演算。
This kind of assertion seems to require special r nlanguage extensions and has led people to suggest introducing r nfirst - order predicate calculus 这种情况下的断言似乎就需要实现特定的语言扩展,于是一些人建议引入一阶谓词演算。
In this paper , the original extended relational model has been improved by adopting mfm in the research of incomplete information database 本文将三值逻辑谓词演算系统mf ~ m应用在不完全信息数据库的研究中,对原有的扩充关系模型做了改进。
Informally , xquery is designed to be able to construct any xml document that can be computed from input xml documents using the power of the first - order predicate calculus Xquery被非正式地设计为可以构造xml文档,而这些xml文档是通过对输入的xml文档进行一阶谓词演算得出的。
The medium logic propositional calculus system mpm and the medium logic predicate calculus system mfm are new logic systems . they are fit for dealing with incomplete information 中介逻辑命题演算系统mp ~ m和中介逻辑谓词演算系统mf ~ m是一种适用于处理不完全信息的新的逻辑系统。
So anything that you may want to express on a complex object that would seem to require first - order predicate calculus can be expressed actually quite nicely within the confines of the programming language 所以对于一个复杂对象,任何看起来需要一阶谓词演算才能描述的东西,实际都可以在编程语言范畴内实现十分精细地表述。
This paper introduces first - order predicate calculus and assertion method from precondition to postcondition into the research of refactoring . and a logic deduction system is put forward in this paper : refactoring reliability deduction system 引入了一阶谓词演算和前后断言方法,并且自定义了一个重构可靠性证明的逻辑推理系统:重构可靠性推演系统。
