As knowledge block in knowledge base is fuzzy and is obtained randomly, we study the rough set model based on random fuzzy rough sets.
当知识库中的知识模块既是模糊的又是随机得到的，我们定义了基于随机模糊集的粗糙集模型。
By using fuzzy random variable theory and fuzzy set theory, the concept and its calculation method of fuzzy random characteristic quantity of safety grade are put forward.
分别运用模糊随机变量理论和模糊集理论而提出了安全等级模糊随机特征量和安全等级模糊特征量的概念及其计算方法。

The result shows that in the view of the fuzzy set, we can not only describe fuzzy phenomena, but also handle the problem of classic random statistics.
研究结果表明：模糊集的基本思想不仅可以用来描述模糊现象，还可用来处理纯随机问题。
If a fuzzy random event is described by the mapping on the measurable space, its measure value can be calculated by the basic formulations which have been set up.
若一个随机模糊事件由定义在可测空间上的映射刻划，则可把已建立的基本公式用于求该事件发生的测度值。
