基于正向规则演绎系统 forward rule based deduction system
对于智能系统中的两种推理机制，即正向规则推理和类比推理，进行了较详细的描述。
Two kinds of reasoning mechanism, the forward regular reasoning and the reasoning from analogy, are described in detail.
为了实现实验操作的正确性检查，采用产生式系统定义实验规则，使用正向推理策略进行规则匹配。
To implement the check-up of the operations, production system is used to define the experimental rules, and forward reasoning strategy is used for rule match.
描述一种诊断型专家系统，它统属于基于规则的产生式系统，推理机是核心部分，分别采用了正向、反向推理技术。
The system is a rule-based production system. Inference engine is the core part of expert system. We use forward chaining and backward chaining at the same time.
