【摘要】 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.更多还原

【Abstract】 Puts forward the data generation of attribute lower limit value and attribute upper limit value,gives the data generation model of attribute lower limit value,attribute upper limit value;puts forward the genetic-evolutionary theorem of metal materials,genetic evolutionary-genetic mutable principle of metal materials.By these data models,we discuss the way discovering the new metal materials;as for the new metal materials which are discovered recently,we prove their existences by instances,the instances in this paper illustrate that S-rough set and its attribute value model are new ways of the new materials discovery of materials science.更多还原
