给出属性下界值,属性上界值的数据生成概念,给出属性下界值的数据生成模型,属性上界值的数据生成模型;提出金属材料的遗传-进化定理,金属材料的遗传进化-遗传变异原理.利用这些数据模型讨论了发现新金属材料的方法;对于新发现的新金属材料用例子证明它的存在,本文的例子说明,S-粗集和它的属性值模型是材料科学中新材料发现的一个新的工具.
The concept of data generation under the lower bound and the upper bound of the attribute is given. The data generation model of the lower bound of the attribute and the data generation model of the upper bound of the attribute are given. The genetic-evolutionary theorem of the metallic material, the genetic evolution of the metallic material, The principle of mutation is discussed.The method of discovering new metallic materials is discussed by using these data models.The new metallic materials which are newly discovered are proved by the examples.Examples of this paper show that the S-rough set and its attribute value model are new in material science A new tool for material discovery.
