摘　　要：根据实验数据研究了规整填料层压降的关联，导出了规整填料层压降的关联式，计算表明，与实验数据相吻合。各种规整填料在不同空塔气速下的压降计算误差一般在±１５％以下，准确性优于文献公式，计算简便，为规整填料层压降的计算提供了可靠的方法。The relation of pressure drop in the regular stacked packing bed is studied by means of the experiment data, and this rela- tion is derived also. It is indicated that the calculation results are tallied with experimental data. The calculation error of pressure drop under the different speeds of free tower for the various kinds of regular stacked packing is in general below the ± 15%, the caculation accura- cy is better than that of any equation in document, so a reliable method is provided for calculating the pressure drop in the regular stacked packing bed.
