The teaching of phase equilibrium theory in the physical chemistry course encounters some problems, such as the varieties of the phase systems and the knowledge points and the difficulty to understand the abstractive phase diagrams. To solve these problems, a systematic teaching strategy is proposed in this paper. The basic concepts and the laws in phase equilibrium theory are first introduced, and the key points are emphasized. The knowledge points in the chapter were then summarized in a table, including the phase diagram systems, the phase laws, the application of the diagrams, and the involved items. Finally, the general methods for the understanding of phase diagrams were proposed. Some examples were further given to explain how the methods, the phase law, and the lever rule were used in solving some specific problems.

Key words: Phase equilibrium, Phase diagram analysis, Phase law, Lever rule, Teaching strategy
