摘要
S-粗集(singular rough sets)具有两类形式:单向S-粗集(one direction S-rough sets)和双向S-粗集(two direction S-rough sets)。S-粗集具有遗传特征、记忆特征。把S-粗集与材料科学进行学科渗透,互补共享,给出新金属材料的发现-识别的讨论,利用属性生成模型给出新金属材料的属性值分析,给出的结果与实际相符。S-粗集是粗集研究的一个新方向,是新材料发现-识别的一个新的数学工具。
S-rough sets（singular rough sets）have two forms, one direction S-rough sets, and two direction S-rough sets, and they have heredity characteristics and memory characteristics. The S-rough sets are penetrated and shared with materials. The new metal material discovery-recognition is discussed. By use of attribute value generation, the attribute value analysis of new metal material is made and the results presented coincide with the practical results. The research on S-rough sets is a new direction, and S-rough sets is a mathematical tool for new material discovery-recognition.
