摘　　要：从能量公设出发,论述了吉布斯自由能判据的一般形式,由此分析了多种能形式存在时的毛细现象过程并得到了毛细现象过程一般的毛细管公式,结果表明:毛细现象过程是多种能形式的变化和相互作用的过程,毛细现象的结果由系统中各种能形式的相互作用和变化共同决定.从能量公设分析毛细现象过程,不仅揭示了毛细现象的实质,而且扩展了毛细管公式的应用范围,还开拓了处理毛细现象的思维方法.The general form of the Gibbs fleeenergy criterion is discussed from the energy postulate. The capillarity process including different kinds of energy was analyzed, and the general formula of the capillarity process was established. The results show that capillarity phenomena is the process of different kinds of energy change and reciprocity, and the results of capillarity phenomena was determined by change and reciprocity of different kinds of energy. The discussion of capillarity process from the energy postulate indicate capillarity essential and expanded the application field of the capillarity formula and exploit thinking method of resolve capillarity problem.
