摘　　要：简要介绍了滤纸法测吸力的原理和方法以及国外滤纸率定曲线的研究成果。应用压力膜吸力仪进行了国产滤纸的率定实验 ,得到了国产滤纸脱湿过程的率定曲线和脱湿—吸湿过程率定曲线 ,分析了该率定曲线的性状 ,与国外滤纸的成果进行了比较 。The filter paper method for measuring the suction in soils is described. The homemade quantitative filter paper is calibrated with a pressure membrane apparatus, the suction calibration curves during dewatering and dewatering absorting are obtained. The properties of these curves are compared with those of foreign filter paper, some conclusions have been summarized.
