谓词演算

It introduces the basic knowledge and ideas of mathematical logic and classic set theory, including proposition logic and predicate logic, reasoning calculus and theorem proving methods, basic operations and properties of sets and relations, functions of any sets and their properties, the cardinals of infinite sets, and the applications of knowledge and ideas above in computer sciences.

本课程系统介绍数理逻辑与朴素集合论的基础知识，包括：命题逻辑和谓词逻辑、定理的推理演算和机器证明方法，集合和二元关系的基本运算和性质、任意集合中的函数及其性质，无穷集合的基数，以及上述知识在计算机科学中的应用。

The similarity logic calculus systems based on incomplete information and incomplete case knowledge is constructed by using a first order modal logic and a simplified second order predicate calculus. The grammar、semantics and inference rule are described.

采用传统的一阶模态谓词逻辑和简化的二阶谓词逻辑分别构建了基于信息不完整和实例知识不完整的相似性逻辑演算系统IISL和IKSL，给出了系统的语法、语义和推理规则。

The atom ic 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。

After this, American Logician Kurt Godel proved the completeness theory of predicate calculus. This means the completion of the base of Modern Logic.

之后，美籍逻辑学家歌德尔一阶谓词演算的完备性定理，这标志着现代逻辑基础部分的完成。

So we present an algorithm based on reachability analysis, and a more complex one which uses a stronger temporal logic (timed predicate μ, calculus) and can verify more properties.

在模型检测的算法方面，本文首先给出了时间符号迁移图上的一个可达性分析算法，随后还定义了能刻划更复杂性质的实时谓词μ演算并给出了检测这些性质的相应模型检测算法。

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。

But what weve found is that apart from the agents mechanisms, which has been in eiffel now for a number of years, theres really no need for introducing first-order predicate calculus, or there exists operators.

但我们发现使用 eiffel 中已经存在多年的代理机制就可以解决，完全没有必要引入一阶谓词演算和 there exists 操作符。

Also, first-order predicate calculus isnt good enough anyway.

同时，从各方面来说，一阶谓词演算都不是足够好。

The problem solving and inference functions will be provided by the hardware inference mechanism,the control mechanism,parallel processing,the logic programs developed on these machines and the software system for high-order predicate calculus.

FGCS的功能可分成3类：问题的求解和推理功能、基于知识的管理功能和智能接口功能问题的求解和推理功能将由硬件推理机制、控制机制、并行处理，以及在这些机制上开发的逻辑编程及高阶谓词演算软件系统提供。

But what we've found is that apart from the agents mechanisms, which has been in Eiffel now for a number of years, there's really no need for introducing first-order predicate calculus, or there exists operators.

但我们发现使用Eiffel中已经存在多年的代理机制就可以解决，完全没有必要引入一阶谓词演算和there exists操作符。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
