论文摘要
线性介电热力学是正式开发的，以探索介电常数的等温和绝热温度 - 压力依赖性。 光学材料的折射率在文献中被广泛测量：它既取决于温度和压力。 建立介电常数的等温温度依赖性的论点是一种热力学依赖性，因此适用于描述材料中电子云和电子共振的所有物理模型。 在所有温度下，位移场与电场的等质斜率通过一个单位质量系统中的绝热介电常数来描述。 由于介电常数的温度依赖性的曲率变化，该斜率通过熵的电子部分在高温下不稳定。 光学电动材料的电子熵贡献具有负热容量，这是不可接受的。 介电常数的温度和压力依赖性仅取决于特定体积，因此等齿始终为正。 介电常数的一种新的通用形式遵循此假设：介电常数与特定体积的平方根成正比。
Linear dielectric thermodynamics are formally developed to explore the isothermal and adiabatic temperature - pressure dependence of dielectric constants. The refractive index of optical materials is widely measured in the literature: it is both temperature and pressure dependent. The argument to establish the dielectric constant's isentropic temperature dependence is a thermodynamic one and is thus applicable to all physical models that describe electron clouds and electronic resonances within materials. The isentropic slope of the displacement field versus the electric field at all temperatures is described by an adiabatic dielectric constant in an energy-per-unit mass system. This slope is shown through the electronic part of the entropy to be unstable at high temperatures due to the change in the curvature of the temperature dependence of the dielectric constant. The electronic entropy contribution for optical, thermo-electro materials has negative heat capacities which are unacceptable. The dielectric constant's temperature and pressure dependence is predicted to be only dependent on the specific volume so isentropes are always positive. A new universal form for the dielectric constant follows from this hypothesis: the dielectric constant is proportional to the square root of the specific volume.
