矿渣微晶玻璃组成、结构与性能的关系属于复杂的知识系统,各种参数之间有很强的相互影响、相互制约的关系。因此,知识的选择(即控制策略)成为计算机专家系统推理机的关键。本文采用混合推理方法构建了矿渣徽晶玻璃专家系统的推理模型,并分别介绍了专家系统推理过程中冲突消解的解空间分解策略和系统解释的预制文本和执行跟踪法等控制策略．是整个系统建立和有效运行的基础。
The composition of slag glass-ceramic, the relationship between structure and performance belong to the complex knowledge system, and there is a strong mutual influence and mutual restraint relationship among various parameters. Therefore, the choice of knowledge (ie control strategy) becomes the key to computer expert system inference engine. In this paper, the reasoning model of slag emblem glass expert system is constructed by using mixed inference method. The control strategy of solution space decomposition strategy and preprocessing text and execution tracking method of conflict resolution in expert system reasoning are respectively introduced. It is the foundation of the whole system to establish and operate effectively.
