Export System of Molecular Design for Metal Catalysts

The expert system for molecular design of metal catalysts in the heterogeneous catalytic reactions on gas solid interfaces was programmed using Visual Basic 5 0 structural language. An Access type dynamic database was employed in the knowledge base, which supported multi user and the instant update of data. The VisData was linked which provided strong function, such as appending, modification and search etc, to the knowledge base. To determinate a desire catalyst for a catalytic reaction, accurate computation combining with fuzzy selection was adopted in the inference engine. The window interfaces are very friendly and easy using since a windows type OOD programming method was used. Moreover, after success set up, the expert system can divorced from Visual Basic 5 0 and independently run.
