In this paper, starting from the Grüneisen relation γ=(αBTV)/(CV), we derive its another practical form (γ)/(γ0)=(1+(B′0)/(B0)P)1-(1)/(B′0)(α)/(α0), and whose validity are investigated along with the relation between it and another expression on the pressure correlation of Grüneisen parameter.%从格林乃森关系γ=(αBTV)/(CV)出发,导出了它的另一种实用的形式(γ)/(γ0)=(1+(B′)/(B0)P)1-(1)/(B′0)(α)/(α0),并且对该式的可靠性以及同格林乃森参数压力相关的其它表达式的关系进行了讨论.
