讨论了与软集的每个参数相关的逼近空间的概念，定义了与软集相关的逼近空间。对于宇宙U的任何子集X，存在与软集的每个参数相关联的U的模糊子集，也存在与软集相关联的模糊子集。此外，集合U上的每个软集都产生P(U)上的模糊软集，并导出P(U)上的软等价关系。(C)2011爱思唯尔B.V.保留所有权利。
Concept of an approximation space associated with each parameter in a soft set is discussed and an approximation space associated with the soft set is defined. For any subset X of the universe U, there is a fuzzy subset of U associated with each parameter of the soft set, also there is a fuzzy subset associated with the soft set. Furthermore each soft set over a set U, gives rise to a fuzzy soft set over P( U) and induces a soft equivalence relation over P(U). (C) 2011 Elsevier B.V. All rights reserved.
