摘　　要：杠杆规则是物理化学相平衡理论中一个重要规则,主要适用于多组分体系的两相平衡体系。通过对二相和三相平衡条件进行分析,得到适用于多组分系统多相平衡的普遍化杠杆规则,并将其应用到具体的物理化学习题中。实践表明,掌握杠杆规则的普遍适用性,可为解答物化习题提供新思路,有利于提高学生灵活应用杠杆规则分析、解决问题的能力。The lever rule is an important rule in phase equilibrium theory of physical chemistry,which is mainly applicable to the two-phase equilibrium systems of multicomponent systems.A generalized lever rule for multicomponent system is obtained based on the analysis of two-phase and three-phase equilibrium conditions.The generalized lever rule is applied to specific physical chemistry exercises.It is found that grasping the universal applicability of lever rule will provide a new way to solve the physical chemistry exercises,and it can also improve students'ability to analyze and solve problems flexibly using leverage rules.
