Study On Complex Thermal Analysis System Resolving

This article studied on the method of resolving the complex thermal analysis system curve. Chemometrics is a method applied widely in many field of complex analysis systems. However, it doesn't yet be applied in thermal analysis. This article want to resolve the complex thermal analysis system by Chemometrics method. In the research process, according to the principle of thermal analysis, we found that the data of thermal analysis system was non-linear, which was the reason Chemometric method couldn't be applied in thermal analysis system. It was the no-linear reason of thermal analysis system that was the mass of sample change continually in measure process. However, it could be transformed into linear system. When the data was extracted from a small range of temperature or time, the mass of sample could be looked upon appro-ximately invariable. Under this condition, thermal analysis could be looked upon approximately linear. These microcosmic linear systems could be resolved by Chemometricsmethod. The whole data of thermal analysis could be looked upon combination of such microcosmic systems. Thess microcosmic systems were black systems. The Target Factor Analysis method was the proper method to resolve this microcosmic systems. In order to verify the new method, we selected NickelSulphate and Aluminum Sulphate mixture to resolve its DSC curves. By Target Factor Analysis method, we resolved the thermalanalysis curve of the mixture, and got the individual thermal analysis curve of each matter. Simultaneously, this articlediscussed the limit of the new method and the factors influencingthe method. This new method has not been reported on anyliterature by now.
