汞压缩因子对压汞法计算结果的影响

The effect of the mercury comlressibility on calcu-lating results of mercury porosimetry

借助空白压汞实验,进行了汞的可压缩性研究。采用合理的数学模型拟合实验数据,建立了汞压缩因子α在升压及降压过程中与压力P的函数关系。把它用于实际的孔隙结构参数计算,通过对比、分析发现,汞压缩因子对压汞法计算结果的影响不能忽略。

The mercury compressibility was studied with blank experiments of mercury porosimetry in this paper. With the experimental data fitted with a reasonable mathematical model, the functional relation between mercury compressibility a and pressure P was established in the process of increasing and decreasing pressure. While calculating the parameters of pore texture,it was found by comparison and analysis that the effect of the mercury compressibility on calculating results of mercury porosimetry can not be neglected.
