在自建的汽液平衡装置上，测定了压力为 ４．００～１０１．３２ｋ Ｐａ 条件下近 １５０ 个窄馏分汽液平衡常数 Ｋ 值；回归了 ４ 个 Ｋ 值计算式，回归式 Ｋ 值最大平均绝对偏差为７．０％ ，泡点温度的最大绝对平均偏差为 ６．０ ° Ｃ。
In the self-built vapor-liquid equilibrium device, the equilibrium constant K value of nearly 150 narrow fractions under pressure of 4.00 ~ 101.32k Pa was measured. Four K values were calculated and the regression K value was the largest The average absolute deviation was 7.0%, and the maximum absolute mean deviation of bubble point temperature was 6.0 ° C.
