一、一个令人费解的概念——熵我们在中学时代便学习了热力学第一定律:物质既不能被创造也不能被消灭,只会从一种形式转变为另一种形式。导致人们认为物质进步没有止境,财富增长没有限度。可以高枕无忧、随心所欲地滥用万世不竭的物质和能源,而其可靠保证却是令人深信不疑的科学技术!不幸的是,热力学第二定律却告诉我们:物质虽然可以循环再生,但必须以一定的“衰变”为代价。能量只能不可逆转地往一个方向转化,对人类来说那就是在人类可用领域从可利用 First, a puzzling concept - Entropy We learned the first law of thermodynamics in high school: matter can neither be created nor destroyed, it can only be transformed from one form to another. Leading people to think that there is no end to material progress and there is no limit to the growth of wealth. You can sit back and relax, abuse your everlasting substance and energy as you like, and its credible assurance is a surefire science and technology! Unfortunately, the second law of thermodynamics tells us that although matter can be recycled, Certain “decay” for the price. Energy can only be irreversibly transformed in one direction, which for humankind is available from the human-available area
