守恒定律(拼音 shǒu héng dìng lǜ )是指在自然界中某种物理量的值恒定不变的规律。守恒定律是一种简单的讲法,意思是不管是什么东西,它的量,不论发生什么事,都不会变。 守恒并不代表某种物理量恒定不变,而是某种物理量的增加量恒等于流入量(增加量为负代表减少,流入量为负代表流出)。增加量不等于流入量(比如增加量为正,流入量为0)代表不守恒(比如熵)。 总的说,物理学大约有十二个守恒定律。这些守恒定律越来越重要,尤其对高能粒子物理学更为重要。
守恒定律(Law of Conservation)意思是从物理学角度出发,在孤立物理系统上,物质随著系统的演进而变化,其最终的动量、质量和能量的总和不会改变。

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。
