S-粗集与新金属材料发现(Ⅱ)

S-rough sets and new metal materials discovery(П)

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.

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 geneticevolutionary 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.
