摘　　要：利用Delphi及Access 2000作为软件开发工具,研制了高精度的计算机控制的在线膜器环隙压力测试系统。可准确、方便、可靠地进行旋转横向流膜器环隙内的压力测试和渗透通量计算,亦可用于一般横向流与轴向流膜器的压力及通量测试。对膜微滤过滤机理的进一步研究,提供了有效的手段。An on-line pressure measuring system for annular gap of membrane separator is developed, with the aid of computer. This system has high precision by using advanced software developing tools, such as Delphi and Access 2000. It can detect the annular gap pressure and the permeating flux in the rotary crass-flow membrane separator fairly accurately and reliably, also can be applied to the measurement of pressure and flux for other kinds of membrane separators, and provides the effective means for further research on enhancement mechanism in membrane micro-filtration.
