气体可压缩性与压缩因子

The Compressibility of Gas and the Compressibility Factors

真实气体的可压缩性与压缩因子的大小没有直接的关系,而由它的压缩因子在一 定温度下对压力的偏导数来决定。该偏导数越小,它的可压缩性就越大。

The compressibility of gas isn't related to the compressibility factor directly. It is determined by the partial derivative of its compressibility factor to the pressure at a certain temperature. The smaller the partial derivative is, the greater its compressibility.
