状态方程 Equation of state
在物理学和热力学中,状态方程(英语:Equation of state),也称物态方程,表达了热力学系统中若干个态函数参量之间的关系。特殊的,在热力学中,状态方程是一个热力学方程,描述了给定物理条件环境下物质的状态,例如其温度、压强、体积和内能。状态方程在描述流体、混合流体、固体甚至是研究恒星内部都十分有用。

Equation of state 状态方程(重定向自Virial equation)
![]() In physics and thermodynamics, an equation of state is a relation between state variables. More specifically, an equation of state is a thermodynamic equation describing the state of matter under a given set of physical conditions. It is a constitutive equation which provides a mathematical relationship between two or more state functions associated with the matter, such as its temperature, pressure, volume, or internal energy. Equations of state are useful in describing the properties of fluids, mixtures of fluids, solids, and even the interior of stars. |
