Abstract In accordance with the idea of generalized phase rule, we have studied the necessary condition of existence of predominance area of phase diagram, in which the number of required message input has been reduced to minimum, and set up the computer program for automatically drawing and calculation. In this program system, it contains the following 7 functions: (1) automatically balance the stoichiometric constants of all possible reactions, (2) carry out the Gibb,s free energy calculation of all possible reactions, (3) automatically cancel out the non-existence phase in the designated condition, (4) calculate out all of the locations of 3 phase intersections, 2phase cross lines, (5) find out the phase name, (6) find out the temperature profiles to be interested in, and (7) select the appropriate parameters. This program system has been used in the field of pyrometaUugy for explaining how to select the best operating condition.
