Among the decomposed synthesis reasoning sources , the field intensities were defined by dependency and classification methods based on the concept of positive region , by discernibility matrix method based on the rate of appearance , and by mutual information , condition entropy and mutual information gain rate methods based on information theory 在分解得到的综合源中，基于正域的概念，用依赖度和分类质量方法定义了场强，根据属性出现频率， ?用差别矩阵定义了场强，并结合信息论，通过互信息、条件熵和互信息增益率定义了场强。
	4.	To the problem that finding rules in enormous data is very time - consumable and the expansibility of existed algorithms is not very good , the thesis proposes a new method to discompose large data table based on the concepts of positive region and the importance of attribute in rough set theory . existed algorithms of rule deduction can be applied directly on the tree structure obtained by partition and the times for computation will be reduced observably . validation of information entropy on the partition structure shows that the partition of data table will not lead to the loss of information , while the computing speed increases at the same time , which reflects the practicability and rationality about the partition of large data table 针对海量数据处理起来极为耗时，现有算法拓展性较差的问题，基于rough集理论中的集合正域概念以及由此定义的属性重要性概念，提出一种大型数据表分解算法，现有的规则归纳算法可直接在分解得到的树型结构上应用，将大大降低知识发现的时间，并从信息理论的角度利用信息熵概念对该分解结构进行了验证，分析了这种分解的实用性及合理性，揭示了这种分解结构在提高计算速度的同时不会损失信息量。
