The absolute frequency is a function related to the traditional frequency and how long the certificate has been used since the time it was used the last time. In the paper the authorization module based on the attribute certificate is implemented using the C++ language. It also has been added to the GT4 to provide to the certain Grid application with a new authorization schema.

The third is the evolution of knowledge: Because of the limit of human's cognition, knowledge in a person's brain keeps on evoluting. So the knowledge in an intelligent system which simulates cognition should also evolute. The evolution of knowledge in the CM includes the evolution of background knowledge and problem solving knowledge.

最后是系统知识进化的思想：因为人的认识能力的局限性，人的知识一直处于不断的进化过程中；体现知识模拟的知识库系统也应当是进化的；CM方法论中的进化过程包括背景知识进化和面向问题求解知识对象的进化，为此，CM方法论中定义了关于知识对象及其背景知识的一系列操作。

Then the algorithm was used to get the seven parameters of viscosity model of W-Ni-Fe heavy alloy and 316L stainless steel feedstock, which provide the necessary material data for quality forecast of mold core part made of stainless steel and heavy alloy tungsten ball, and for optimal design of mold and process parameters, which establishes the foundation of material database of MIM. In the research of visual simulation software development, in order to build the software system model and flow analysis algorithm based on Cross-WLF viscosity model, and realize functions such as pre-processor, solver, parameter regress, data management, graph operations, some advanced software methods as OOSE (Object Oriented Software Engineering) and UML were applied to set up user model, static model and dynamic model of MIM simulation software. These models describe system function, event flow, structure and relation of classes, object interaction, structure of database and I/O file format.
