    Firstly, through further research of the Rough Sets theory, we refine the granule of the classification, and then change the decision attribute of the decision table. Base on these and the relationship between Rough Sets theory and Evidence theory, we compute the evidence's basic belief assignment through classification, and thus we realize the acquisition of evidence.

Generally, reasoning theory can be divided into certainty reasoning t heory and uncertainty reasoning theory. Traditionally, certainty reasoning theor y is used to detect and diagnose satellite faults. However, in practice, it is d ifficult to detect and diagnose some satellite faults automatically only by use of certainty reasoning theory. The reason is that detection and diagnosis of the se faults requires reasonable reasoning and fault tolerant capability, but cert a inty reasoning theory can not realize the capability. Fortunately, uncertainty r easoning theory can meet this requirement. Now, it is attracting attention of ma ny researchers and practitioners in the space field all over the world that unce rtainty reasoning theory is applied to detect and diagnose the satellite faults which can not be handled properly by certainty reasoning theory. Uncertainty rea soning theory includes several kinds of theories, such as inclusion degree theor y, rough set theory, evidence reasoning theory, probabilistic reasoning theory, fuzzy reasoning theory, and so on. This paper introduces three new methods to de tect and diagnose the satellite faults, in which inclusion degree theory, rough set theory and evidence reasoning theory of the uncertainty reasoning theory are used respectively.

推理理论一般分为确定性推理理论和不确定性推理理论。传统的卫星故障检测和诊断应用的是确定性推理。然而 ,在卫星故障检测和诊断的实践中 ,仅使用确定性推理是很难对某些故障进行检测和诊断的 ,因为这时需要合情推理和容错能力。不确定性推理理论可以满足此要求。目前 ,航天领域的许多专家和实际工作者正致力于应用不确定性推理理论检测和诊断那些用确定性推理无法检测和诊断的故障。不确定性推理理论包括诸如包含度理论、粗糙集理论、证据推理理论、概率推理理论、模糊推理理论等。笔者研究的卫星故障检测和诊断的三种新方法 ,分别应用了包含度理论、粗糙集理论和证据推理理论

This paper first reviews the theories and evidence about technology innovation and diffusion,then based on the Fagerberg model.This paper analyses the influence of technology innovation and diffusion on the regional productivity to using the Chinese data from 1991 to 2002. The empirical results show that the gap of productivity among local regions has extended continuously; the impact of technology diffusion main in local regions, FDI has little influence on the growth of regional productivity; there is not "Backword Advantage" for most regions of China; the distance between regions has negative influence on technology diffusion.

首先简要回顾了与技术创新扩散对经济增长影响有关的理论和证据,然后以Fagerberg的模型为基础,利用中国1991~2002的相关数据,对技术创新扩散对区域生产率增长差异的影响进行了回归分析。本文的结论主要有:国内地区间生产率差距呈不断扩大之势;技术扩散对地区生产率的影响主要反映在国内地区间的扩散上,外商直接投资对地区生产率增长的作用不大;对中国大部分地区而言,并不存在技术上的"后发优势";距离对地区间的技术扩散存在负影响。

Rough Set Theory is another mathematical tool used for dealing with fuzzy and uncertain knowledge besides Probability Theory,Fuzzy Set Theory and Evidence Theory.In order to solve the problems with the same condition attributes but different decision-making attributes,which often appear in the use of Rough Set Theory,we put forward an algorithm of correcting incompatible rules.In other words,according to the concept of relative error rates of classification,under the precondition...

Rough Set Theory is another mathematical tool used for dealing with fuzzy and uncertain knowledge besides Probability Theory,Fuzzy Set Theory and Evidence Theory.In order to solve the problems with the same condition attributes but different decision-making attributes,which often appear in the use of Rough Set Theory,we put forward an algorithm of correcting incompatible rules.In other words,according to the concept of relative error rates of classification,under the precondition of maintaining the original knowledge classification unaltered,we correct the incompatible rules though comparison of the magnitudes of the relative error rates of classification.At last,we verify the feasibility of the arithmetic with an experience of classification of radars.

粗集理论是继概率论、模糊集、证据理论之后的又一种处理模糊和不确定性知识的数学工具。针对粗集理论在实际应用中常常出现的条件属性相同而决策属性不一致问题,提出了一种修正不相容规则的算法。即从相对错误分类率概念出发,在力求保持原知识分类能力的前提下,通过比较不相容规则的相对错误分类率大小,从而对不相容规则进行修正的算法。并通过雷达分类实例验证了算法的可行性。
