| 摘 要： | 判断某个状态变化过程是否自发，是物理化学课教学的重点和难点，可以从自发过程的特点及三个判断自发过程的状态函数之间的关系进行分析，得出自发过程的判据，并从三修养在适用的条件下，归纳出各判据的适用范围，使学生易于掌握。

| Abstract: | Judging whether the changing process of a certain state is spontaneous is the priority and difficulty of physical and chemical teaching.The criterion is obtained by analysis of the characteristic of the spantaneous process and the relation between threestate functions of the spantaneous process.Based on the conditions suitable for three criteria,We find the scope of application of each criterion so that students can easily grasp them. |
