【摘要】 依据ＡＩ基本理论设计了化工仿真培训系统的智能绘图子系统总体结构。一个智能系统的关键在于其知识表示方法和推理机的速度，根据所涉及的化工仿真工艺流程图域的情况，采用了经典的Ｆ－系统来作为知识表示方法，并特别的设计了首字符串索引的知识库结构，建立了基于网络管理的有效事实串的形成机制，从而加快了事实与规则的匹配速度，实践证明，这些都对提高推理机的速度是有效的。更多还原

【Abstract】 The design and realization of intelligent surporting subsystem for petrochemical process simulation training system are presented in detail. In the subsystem, we express rules and facts in petrochmical simulation process by using of F-system in AI. Because the efficency of intelligent system depends on the reasoning speed of reference, we design the knowledge base structure with first character index, and set up effective facts string forming mechanism. All that we have done increase effectively the speed of reference.更多还原
