## 定义

${\displaystyle Z={\frac {p{\tilde {V}}}{RT}}}$

• ${\displaystyle \ p}$  为压力；
• ${\displaystyle \ {\tilde {V}}}$  为气体的摩尔体积
• ${\displaystyle \ T}$  为温度；
• ${\displaystyle \ R}$ 气体常数

${\displaystyle {\frac {P{\tilde {V}}}{RT}}=1+{\frac {B}{\tilde {V}}}+{\frac {C}{{\tilde {V}}^{2}}}+{\frac {D}{{\tilde {V}}^{3}}}+\dots }$

${\displaystyle \ Z_{c}={\frac {p_{c}V_{m,c}}{RT_{c}}}}$
