如何用电容器将热能转化为可用的功
How to transform, with a capacitor, thermal energy into usable work
摘要：
考虑到介电常数的温度依赖性，以研究电容器中的能量变化，该电容器遵循冷的和热的热库之间的循环。在这个过程中有一个净能量增益，原则上可以转化为可用功。这篇文章很简单，可以用来与热衷于大学普通物理或热力学课程的本科生。进一步的实验工作和可能的技术应用的建议。
英文摘要：
The temperature dependence of the dielectric permittivity is taken into account to study the energy change in a capacitor that follows a cycle between a cold and a hot thermal reservoirs. There is a net energy gain in the process that, in principle, can be transformed into usable work. The article is simple enough as to be used with keen undergraduates that have taken a university general physics or thermodynamics course. Further experimental work and a possible technological application are suggested.
