| To inquire the related information fast establish dangerous medium to leak emergency decision system and make diagnosis and first aid promptly reliable to get help from within to save mutual, fire control, shot-off of loss wait for correct decision . It is an important part of Decision system of emergency. Information of dangerous chemical fast system for dangerous medium leaking. Its primary mission is the applications the fuzzy inquiry technology to carry on the inquiry of each kind of dangerous chemical information promptly.The paper introduce that project process, function and the content of system.Chemistry was the experimental science, it accumulates the massive information in the practice.In recent years, with the massive accumulations of chemistry data and universal use of database the people realized that it is extremely difficult and not full to make use of the magnanimous data gradually.Therefore, as a kind of recent information technology, the data mining is applied to chemistry. The key of this technical is to solute the problem that how to discover the information and the knowledge that is not obvious and has the latent application of value from the magnanimous chemistry data. |
