In this paper, granularity in rough set theory is used to describe rules based on the concept of rough degree. A tool for knowledge dependent relation diagram is put forward. Then dimensional knowledge granularity decision space and the same construction mapping decision space based on multi-decision sorts is established, and decision algorithm based on KDRD and decision space is introduced. Finally, through combining with the technique of fault diagnosis, it is proved that the approach is very appropriate to the intelligent decision system.

The so called indirect integral operation means that Eular angles can be gotten from the direction cosine matrix which is received by the integral operation of quaternions or direction cosine.

飞行器导航中，姿态角的获取可以通过直接或间接的积分运算求得的，所谓间接获取即是指通过四元数或方向余弦的积分运算求得姿态矩阵，再从姿态矩阵中提取姿态角。

This theoretical paper discusses the model that, as a result of the social process of disintermediation enabled by digital media, traditional intermediaries are replaced by what this author calls apomediaries, which are tools and peers standing by to guide consumers to trustworthy information, or adding credibility to information.

Classic rough set theory based on equivalence relation takes complete system as object of study , and divides the region into some non-intersect equivalence class; But, in the real life, because of the errors in data measuring, understanding of data, or the restriction in data collection , it can make the decision-making system incomplete, that is, value of attribution of some objects is unknown, which restrains development of the theory to practical direction.

经典粗糙集理论以完备系统为研究对象，以等价关系为基础，通过等价关系将论域划分为互不相交的等价类；然而，在现实生活中，由于数据测量的误差，对数据理解或获取的限制等原因，使得在知识获取时往往面临的是不完备系统，即可能存在部分对象的一些属性值未知的情况，这就极大地限制了粗糙集理论向实用化方向发展。
