应用专家系统开发工具，以Ｐ５０７－ＨＣＩ－煤油体系分离镨钕为例，首次开发了稀土溶剂萃取分离过程的故障监测与诊断专家系统ＲＥＭＤ。该系统可对分离过程进行日常监测及故障诊断，并能迅速指出故障原因及修复调整的办法，以指导生产实践，确保产品的质量和产量。在实践中经过了考证。 Application of expert system development tools to praseodymium neodymium P507-HCI-kerosene system, for example, for the first time developed a rare earth solvent extraction and separation process fault monitoring and diagnosis expert system REMD. The system can carry out daily monitoring and fault diagnosis of the separation process, and can promptly identify the cause of the malfunction and repair and adjustment methods to guide the production practice to ensure product quality and yield. In practice after research.
