摘要

在静态电磁场中，线性均匀介质的麦克斯韦应力张量意味着由相互场能密度引起的一种新的压力形式。当把它引入介质的基本热力学方程时，我们就得到了一个新的压力-体积功项。新项与适当的电磁功项结合，自然就得到了目前通过工作假设得到的众所周知的形式。

Deriving a working hypothesis in thermodynamics on electromagnetic work from first principles

The Maxwell stress tensor for the linear and uniform media in static electromagnetic field implies a new form of pressure caused by the mutual field energy density. When it is introduced into the fundamental thermodynamic equation for the media, we have a new pressure-volume work term. The combination of new term and proper electromagnetic work term naturally gives the well-known form that is currently obtained by a working hypothesis.
