Exergy:热力学第二定律的实践者

Exergy:the Exertion of the Second Law of Thermodynamics

大多数研读热力学的学生都对熵抽象的观念感到痛苦。尤其甚者,他们对热力学第二定律的陈述及如何应用都觉得困惑。这篇短文借着Smith等人著名热力学教科书上的范例阐述有效能量(Exergy)的观念,并进而彰显热力学第二定律的意涵。

Most of the students who study thermodynamics are inflicted by the abstract notion of entropy. Especially, they are perplexed by the statements the second law of thermodynamics and its applications. This communication starts with an example from the famous Thermodynamics text of Smith et al. , and illustrates the concept of exergy as its fulfillment of the significance of the second law of thermodynamic- s.
