热力学状态

热力学状态是指一组描述热力学系统的状态。个别的参数一般会称为状态变量状态参数或是热力学变量。只要一热力学系统中有足够多的已知状态,其他的状态就已被确定,而所需要的状态数量视系统复杂程度而定。

例如一封闭简单系统,其中有二公升的氧气,压力为一大气压,此即为此系统的热力学状态,其他的状态变量 (温度、熵、内能)等都已被确定。

Thermodynamic state 热力学状态

For thermodynamics, a thermodynamic state of a system is its condition at a specific time, that is fully identified by values of a suitable set of parameters known as state variables, state parameters or thermodynamic variables. Once such a set of values of thermodynamic variables has been specified for a system, the values of all thermodynamic properties of the system are uniquely determined. Usually, by default, a thermodynamic state is taken to be one of thermodynamic equilibrium. This means that the state is not merely the condition of the system at a specific time, but that the condition is the same, unchanging, over an indefinitely long duration of time.
