Tn view of the deficiency of classic probabilistic rough set model,we introduce the probabilistic rough set model over two universes which exist a compatible relation,two kind of approximation operator based on the multi-valued mapping were defined,which is called Generalized Probabilistic(I) and Generalized Probabilistic(II),the mathematic properties were discussed.
针对经典概率粗糙集模型的不足,将其论域推广到两个具有相容关系的论域上,借助集值映射分别定义了两种形式的广义概率(I)型和广义概率(II)型粗糙集近似算子,并讨论了相应的数学性质。

The classical probability rough set model had been established on the basis of universe of discourse in equivalent relation.

补充资料:Pro/Engineer Drawing 表面粗糙度
1 概述
我们可以添加标准形式的表面粗糙度,下面列出了这些标准形式
Generic 切削加工 非加工
no_value
standard value value value
7.3.2 添加表面粗糙度
选择 DETAIL> Create > Surf Finish.
如果你还没有添加任何一种表面粗糙度,或者需要添加另一种类型的表面粗糙度,你需要“Retrieve”表面粗糙度;如果你需要添加已经存在的类型,你可以使用"pick Inst"选项;也可以使用"Name"选项
选择表面粗糙度的放置方式(有引线箭头、附着实体等)
选择需要的放置实体
输入表面粗糙度的值
