应用Lagrange中值定理证明一般热传递过程中的熵增

Using the Theorem of Lagrange Proves the Principle of Entropy Increasing in the General Heat Passage Process

热传递过程中的熵增加原理的证明是学生在普通物理和大学物理学习中的一个疑点,笔者应用学生所熟知的Lagrange中值定理对其进行证明,可以有效地破解学生的疑点。

The principle of Entropy increasing is difficult for students to understand during their learning process of general physics and college physics.We prove the principle of Entropy with the students' familiar Lagrange's Theorem of intermediate value to make them understand the Entropy well.
