摘要：
Centrifugal techniques are proposed for determining the hydraulic conductivity of cores of natural soil. The redistribution of water within a moist soil core after centrifugation is measured gravimetrically and analyzed in terms of the moisture flow equation. Analytical solutions for two cases were used to calculate hydraulic conductivity. Cases for the outflow of water from a soil core during centrifugation were also examined mathematically.
