There are such some persons in the world , they are great since they are outstanding or uncommon because they are beautiful or commemorated forever by people resulted from their standing for classical fashion ; there are such some things in addition in the world , they are unique because they are rare , or unvarying as they have been ground by years or become the imperatorial symbol due to their valuable incomparability pokings is such outstanding material 世界上有这样一些人，因其杰出而伟大，因其美丽而非凡，因其代表着经典时尚而永远被人纪念世界上还有这样一些事物，因其稀有而独特，因其历经岁月磨砺而恒久，因其珍贵无比而成为至尊的象征铂金斯便是这样的非凡之物。

In this paper , our work begins with the classification of indefinite information presented in the first chapter and these classes include randomicity , fuzziness , non - partitionality , incomparability , incompleteness and unreliability . and the corresponding theories and methods of studying these information are simply described . then the following chapter of this paper discusses the approximate processing of rough boundary region - sort of problem of non - partitionality 本文第一章从不确定问题的定性描述出发，将不确定性信息分为了随机性不确定性信息、模糊性不确定信息、不可区分性不确定信息、不可比较性不确定性信息、不完全性不确定性信息和不可靠性不确定信息，并对各种不确定信息的产生和处理方法进行了简单的概述。

Thirdly , based on our definition of fuzzy preference structure without incomparability , we find out relationships between transitivity properties of large preference relation and strict preference and indifference relation with ^ - transformation of lukasiewicz t - norm . for example , we point out that the w - transitivity of large preference relation can derive the same transitivity of strict preference and indifference relation 在作者所给出的模糊偏好结构定义的基础上，在无不可比关系的条件下以及lukasiewicz ，模的尹变换叽的意义下，讨论了大偏好、严格偏好及无区别关系之间的传递性性质的联系，例如我们指出了大偏好关系的叽传递性可导出严格偏好以及无区别关系的叽传递性等。
