一种面向测试的RTL行为抽象与蕴含方法

针对寄存器传输级（register transfer level,RTL)行为的抽象，提出了一种层次化的带条件的表示，这种抽象的行为是面向测试的，它不仅表达简单，而且能很方便地进行蕴含操作，通过抽象，电路可以规范为行为集，并代替电路本身进行功能测试向量的生成，在测试生成过程中，大量地应用蕴含操作何以使其中的行为得到简化，并极大地提高了系统的效率。

Method for Risky Multiobjective Group Decision-Making and Its Application

The multiobjective group decision-making problem under risk is common in reality. This paper focuses on the study about risky multiobjective group decision-making problem where the index value is not certain. We give indexes classifying method and index normalizing formula of this type problem. By building objective function that minimizes general weighted distance from every alternative to the relatively best and worst alternative, the optimal membership degree of every decision-maker to every alternative can be obtained, and by building another objective function that minimizes general weighted distance from the optimal membership degree of every decision-maker to every alternative to the group optimal alternative and the group inferior alternative, the optimal membership degree of every decision-maker to every alternative can be obtained, which are both based on probability theory and fuzzy theory. Aftermost a model is established which collects group preferences. This method provides a new idea and

Business Process Reengineering (BPR) Versus Outsourcing—Critical Perspectives

This article presents a case example involving the renaming of an organizational change process from BPR to outsourcing. The paper discusses the important ramifications of such a name change in that the recognition of outsourcing allowed an organizational commitment to counseling and termination advice. The paper discusses two ways of looking at the name change, one from a critical theory perspective and one from a realist perspective. It demonstrates how theory can provide useful yet markedly different interpretations of such organizational events. Critical theory operates from within what can be termed the transitive epistemological dimension, whereas critical realism tends to emphasize the importance of ontological issues. Each has important things to say about the situation and improves our understanding overall.     

语言符号任意性和象似性的辨证关系

文章运用自组织理论和原型理论对语言符号任意性和象似性的关系进行分析,指出语言符号的任意性和象似性的关系是辨证的,两者看似相对,实则相辅,它们存在于一个整体之中。对语言符号任意性和象似性辨证关系的认识,在英语教学中有着重要的实用价值。     

关于Erdoes猜想的证明

文章对Erdoes猜想中正整数n的值进行分类．除了n为4m-3（m=6R＋1）形的奇数外，逐类直接给出了具体表示。对于n为4m-3形的奇数，文章采用命题转化法及反证法．并用自变量与函数值的一一对应关系证明了Erdoes猜想成立。
