其他的定律，或者可由能量守恒定律导出，或者必须经受能量守恒定律的检验，或者是错误的。

Other laws will be derived by the law of conservation of energy, or verified by the law of conservation of energy. In this paper four questions are discussed.

All right, now what we're going to learn next time and Bob Field is going to teach the lecture next time, is how heat and work are related, and how they're really the same thing, and how they're related through the first law, through energy conservation.

这节课就到这里,下节课将由Bob，Field讲授,我们将学习功与热量的关系，认识到它们在本质上的相同之处，并通过热力学第一定律，亦即能量守恒定律，把它们联系起来。
