幂集 meaning in English
power set
Examples
- Axiom of power
幂集公理 - With the development of fuzzy set theory , all kinds of the structure are upgraded not only from their universes to their power sets but also from their universes to their fuzzy power sets
模糊数学的发展要求各种数学结构不但要由论域向其幂集上提升，而且还要求向模糊幂集上提升。 - With developing fuzzy mathematics , the importance of set value mapping has been highlighted , so that the upgrade of all kinds of the structures , such as ordered , topological measurable structure , etc , have been considered
模糊数学理论的发展突出了集值映射的重要性，各种数学结构需要由论域向其幂集上提升，如序结构的提升，拓扑结构的提升，可测结构的提升等等。 - First we give the conception of multimedia - instance model , which consist of 7 - tuple mi ( s , f , a , a , fi , sv , fj ' 9 , where s is a set of states , which captures a certain structure to store information . f is a set of features , which presents pieces of information of given states , a is a map from sto 2 " . a " is a set of feature - state relations on 2f xs , which reflects the relation between characteristics of state , fi is a set of relations defined on s . which reflects the relation between states
我们首先定义媒体实例的概念，该媒体实例为7元组mi =口，几且， o ，尽sv ， 919其中， s是一个状态集，一个状态捕获一个确定的用于存储信息的结构； f是一个特征集，一个特征反映给定状态中一则有意义的信息；允： s 2 ?是一个从状态到特征幂集的映射，反映一个给定状态中所具有的特征； "是一个在2 ? s上的关系集，它反映状态中特征之间的关系；胆是一个在s上的关系集，反映状态之间的关系； sv是一个状态变量集； fv是一个特征变量集。 - At first the approximate operators of rough sets are modified , so the new operators of union , intersection and complement and approximate power sets are presented . this has enriched rough sets theory from the operator - oriented and set - oriented views . then by combining topology , rough topology and approximate topologies are defined and researched
首先修正粗糙集近似算子，提出近似集的新型并、交、补运算和近似幂集空间，从算子论和集合论两者的角度丰富了粗糙集理论；再结合拓扑，定义和研究了粗糙拓扑、近似拓扑。
