7、表1几点说明：1．F列空气流量校正值V2由下面的公式校正：式中的V1为空气转子流量计在操作状态下的示值，其数字记录于B列中，和为空气转子流量计在标定状态下空气的温度和压强(T1＝293K；p1＝101.3kPa)，和为操作状态下空气的温度和压强，其对应值分别记录于C列和E列，然后将C列和E列数值转化为绝对温度和绝对压强，结果分别列于D列和F列；2．全塔压降Δp直接从压差计读出，其结果记录于H列；3．空塔气速u由下式计算：式中的D为塔径(D＝0.1m)，计算结果列于J列；4．单位高度填料层压降Δp/z，直接用H列数据除以I

8、列数据即得，计算结果列于K列；5．以J列数据为横坐标，K列数据为纵坐标作双对数坐标图得如下结果：从图中可以看出：①干塔操作条件下，之间表现出较好的对数线性关系，塔内不存在滞液量和气-液两相逆流的交互影响；②在同一操作气速下，随着喷淋量L的增大，单位填料层压降显著增大，说明滞液量和气-液两相逆流的交互影响十分显著；③四
