逻辑演算

We shall have occasion to deal with geometry, both Euclidean and non-Euclidean, with arithmetic, algebra, analytic geometry, the theory of irrationals, set-theory, calculus of probability, and mathematical logic.

我们将与算术，代数，解析几何机会几何处理，包括欧几里德和非欧几里德，是无理的理论，集理论，概率演算，和数学逻辑。

In mathematical logic in the study is the main target of all kinds of calculus.

在数理逻辑中研究的主要对象是各种演算。

A new complete disjunctive normal form, which is in the sense of equivalence, to an extension system of medium logical proposition calculus MP is defined and the theorem of its existence and uniqueness is established and proved.

So we can describe the process model in the logic situation calculus based on the virtual enterprise ontology.

这样，我们就可以在虚拟企业本体论基础上，以逻辑情景演算来描述虚拟企业过程模型。

Predicate logic: also predicate calculus, which studies the internal structure of simple propositions.

谓词逻辑：也叫谓词演算，它研究简单命题的内部结构。

Elementary logic and Algebra Propositional calculus, quantifiers.

初等逻辑和代数命题演算，量词。

We first introduce the state of the art of Web Services Composition, and then analyze the relation between Web Service Composition and related theoretical backgrounds. Concerning the two key technologies, service composition method and service composition system, we demonstrate our work.1. Based on semantic Web Service and OWL-S specification, a first-order logic Situation Calculus planning method for services composition is introduced.

本文首先对现有的服务组合相关工作做了比较详细的阐述，在分析了语义Web服务自动组合所涉及的主要理论背景之间的关系和作用之后，针对我们所关注的两个主要技术层面——服务组合方法和服务组合系统阐述了我们的工作： 1、在语义Web服务规范OWL-S的基础上，研究通过一阶逻辑状态演算来规划组合服务的方法。

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。

Having combination of the theory of truth degree in metrology of logic with the theory of ∑-α-tautologies in fuzzy logic, which have been introduced by professor G.J.Wang, the theory of ∑Γ-truth degree was introduced, and its properties which induce a pseudometric on F were investigated. The results gained have complemented and enhanced the original theory, and the work delivers a new frame for fuzzy reasoning.

将模糊命题逻辑中的∑-α-重言式理论与计量逻辑学中的真度理论相结合，在经典二值命题演算系统L中引入了公式相对于有限理论的∑Γ-真度理论，较为详细地讨论了它们的性质，并利用∑Γ-真度的性质在公式集F上引入了ρΓ-伪距离，对原有的理论进行了加强和补充，为在模糊命题逻辑系统的有限理论中讨论结论的程度化问题奠定了基础。

Two intuitionistic systems of firstorder sentential calculus, Hilbert s type and natural deduction t ype, were introduced.

介绍了一阶命题演算的两个直觉主义系统：希尔伯特型及自然演绎型，并证明了这两个系统的等价性，揭示了直觉主义逻辑的内涵及与其他非经典逻辑的关

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
