摘要
理想气体的状态方程 pV =nRθ,是依据三个实验定律进行热力学理论推导的结果 .根据它可以用理想气体实现热力学温标 .pV =nRT是依据实验事实得到的理想气体绝对温标的定义式 .两者的物理意义是不相同的 .
Equation of state pV=nRθ,for an ideal gas,is a result of deducing from three experimental laws based on thermodynamic theories.According to it thermodynamic temperature scale can be realized.pV=nRT is a formula of definition for ideal gas absolute temperature scale from some experimental facts.They have widely different meanings in physics.
