摘　　要：熵是热化学中重要的概念。由于其物理意义的抽象性,中学教师在讲解以及学生在理解该概念时容易产生学科理解偏差。聚焦“熵”教学课堂中的现实问题,从统计热力学基本原理的视角,帮助教师再认识熵和熵增加原理,并提供了教学建议与实例参考。Entropy is an important concept in thermochemistry.Due to the abstraction of its physical meaning,middle school teachers and students are prone to subject understanding deviation when teaching and understanding the concept.This paper focuses on the real problems in the teaching of"entropy",helps teachers re-understand the principle of entropy and entropy increase from the perspective of the basic principles of statistical thermodynamics,and provides teaching suggestions and example references.

关 键 词：熵 熵增加 混乱度 微观结构
