摘　　要：在气液逆向流动中,提出了一种用电导双探针法测量筛孔所处状态的有效方法,以及利用Ex-cel软件处理大量数据的步骤。为气液流动的研究,提供了新的手段。A new dualprobe method of electric conductivity was put forward to detect the liquidgas flow countercurrent through the holes of a dual flow sieve tray. One of the three status——liquid flow, gas flow and blocked——can be observed in an individual hole at a period of time. The Excel software was utilized to deal with a large number of the result obtained.
