摘　　要：At present CALPHAD (CALculation of PHAse Diagram) technique is notcapable of predicting whether there exists intermediate compound,much less predicting the formulae, the number, and the meltingcongruence of intermedi- ate compounds. To solve this problem, a newapproach called the phase diagram evaluation by pattern recognition(PDEPR) was improved. The micro-parameters. Such as the radius andthe electronegativity of the different features in multi-dimensionalspace.At present CALPHAD (CALculation of PHAse Diagram) technique is notcapable of predicting whether there exists intermediate compound,much less predicting the formulae, the number, and the meltingcongruence of intermedi- ate compounds.
