By means of infinite product of evenly distributed probability spaces,the concept of truth degrees of propositions in 3-valued logic systems W_3,G_3,Π_3 and S_3 are introduced,and some properties of distribution of propositional truth degree and certain inference rules are obtained.

利用势为3的均匀概率空间的无穷乘积在W3、G3、Π3及S3系统中引入了公式的真度概念，得到了命题真度分布的一些性质，同时给出了三值真度推理规则。

The resource model of design knowledge representation is proposed based on propositional logic and Cartesion product.

这一模型概括了产品开发中所涉及的各种资源，是对现有知识表示技术的补充。

The concept of relative Γ-tautology degree of formulas in four important propositional logics, Lukasiewicz logic, L(superscript *) logic, Gdel logic and product logic, has been proposed, and basic properties of it are obtained.

基于广义重言式理论，在四种重要的命题逻辑系统Lukasiewicz系统，L系统，Gdel系统和Ⅱ系统中，引入了公式的相对Γ-重言度概念，给出了相对Γ-重言度的若干性质。

At that level we stand to secure an apriori grasp of the primary ampliative move, a move that the material implication at the propositional level merely shadows.

在这个水平上，我们坚持维护对首要的扩展推进进行先天把握，这个推进的实质蕴涵，在命题水平被遮蔽。

My thesis built the theory of predicate logic on the basis of L* propositional logic.

本文在命题逻辑的基础上以系统为背景建立谓词逻辑理论。

This paper summarizes some inferential proof methods in propositional logic and predicate logic by using some examples.

本文结合适当的例题总结了命题逻辑和谓词逻辑的几种常见推理证明方法。

Moreover, predicate logic is the generalization of propositional logic and possesses larger flexibility, so it is very difficult for students to grasp.

而谓词逻辑是命题逻辑的推广，其灵活性就更大，故很难掌握。

And the proposition is the propositional sign in its projective relation to the world.

一个命题就是一个处在对世界的投影关系中的命题符号。

The third part proposes in Luk the concept of lattice-valued truth degrees based on the second part by generalizing truth values from the MV-unit interval(a special MV-algebra) to a general MV-algebra. And the properties of lattice-valued truth degrees suggest that this generalization is natural and reasonable. Because of the equivalence between the two algebra systems, i.e. MV-algebra and lattice implication algebra, it's natural and easy to grade the truth of formulas in lattice-valued propositional logic whose basic algebra system is the lattice implication algebra.

中。 本文第三部分在第二部分的基础上，将Luk中公式的真度值推广到了一般的MV代数上，相对于第二部分的数值真度，给出公式的格值真度，并通过格值真度的性质说明格值真度是数值真度的合理推广。

It combines with a raised noun via predication operation to form a new propositional function and constructs a grammatical sentence with the subject.

它们如果要成为句子的谓语，必须首先通过一个谓词化的操作将性质π转化为命题函数，才能成为合格的谓语并与主语结合形成一个合法的句子。

I was just taking her hand, to help her out of a car, and I knew it.

我只是握着她的手，扶她下车，但我知道这一切。

China and South Korea have excoriated Japan over its approval of new school books which they say whitewash the atrocities committed during Japanese occupation, and anti-Japanese protests have been held in Chinese cities. The lingering bitterness over Japan's past imperialism still threatens to mar relations between the big East Asian powers

中国和韩国强烈谴责日本通过新的中学历史教科书，他们认为这一教科书掩盖了日本在其占领期间所犯下的残酷暴行，反日抗议活动在中国数座城市发生，历史上日本帝国主义制造的痛楚无法被忘却，这有可能破坏东亚强国间的关系。
