试用普遍化Virial方程计算丙烷气体在378K，0.507MPa下的偏离焓和偏离熵。已知丙烷的物理参数为：Tc=369.8K，pc=4.246MPa、ω=0.512。偏离焓与偏离熵的计算公式为：dfrac ({H)^+}(RT)=p[ (dfrac ({B)^(0)}({T)_(r)}-dfrac (d{B)^(omega )}(d{T)_(r)})+omega (dfrac ({B)^(1)}({T)_(r)}-dfrac (d{B)^(1) dfrac ({S^奇)(R)=-(p)_(1)[ dfrac (d{B)^(0)}(d{T)_(r)}+omega dfrac (d{B)^(1)}(d{T)_(r)}] -|||-其中: ^(0)=0.083-dfrac (0.422)({T)^1.6} : ^(1)=0.139-dfrac (0.172)({T)_(1)}^42 Tt、p1分别为对比温度-|||-和对比压力。
