在物理化学教学中存在困难较多的要算热力学基础的讲授了,其中尤以第二定律问题更多。学完物化的学生一般地能记述公式定律,而能基本上掌握了热力学方法并可做些基本运用的就为数不多了。原因是除了理论本身较抽象外也和讲解时偏重于数学关系的推演,对于推理立论的思考路线、根据和物理意义论述的不够或甚简单有关。这就直接地影响到教学质量的提高和学生独立工作能力的培养。这种情况 In the teaching of physical chemistry there are more difficult to be taught on the basis of thermodynamics, especially the second law more problems. Students who complete the course can generally formulate the law of formulas, and one that is able to basically master the method of thermodynamics and can do some basic exercises. The reason is that apart from the fact that the theory itself is more abstract and the emphasis on the deduction of mathematical relations, the thinking line of reasoning is based on inadequate or even simple discussion about the physical meaning. This will directly affect the improvement of teaching quality and students’ ability to work independently. This situation
