介绍一种通过室内短柱蒸发试验测定原状土或扰动土土壤水分特征曲线和非饱和水力传导度的方法，该法需用的设备简单，测试容易．藉助于专门的分析计算程序ＳＭＳＣ，可同时求得θ（ｈ）与Ｋ（ｈ），具有良好的精度，测定轻质土时约需１０天即可完成
A method for determining soil water characteristic curve and unsaturated hydraulic conductivity by uncoiled indoor short column evaporation test is introduced. The method requires simple equipment and easy testing. With special analysis and calculation program SMSC, θ (h) and K (h) can be calculated at the same time, with good accuracy. It takes about 10 days to measure light soil
