【摘要】 通过水平土柱渗吸法测定杨陵土的水动力弥散系数表明，对于低浓度盐溶液水平土柱入渗土，实测的土壤水分扩散率和水动力弥散系数，规律性较好．且有较好的重现性。理论分析是正确的，说明用此法测定土的水动力弥散系数是可行的。更多还原

【Abstract】 The horizontal column infiltration method was used to measure the soil water diffusivity D. and the hydrodynamic diffusion-dispersion coefficients of the Lou soil. It shows that the date determined preserve similarity well and give a good reproducibility during the horizontal column infiltration into the Lou soil with low salt-concentration solution, and so the theoreticatyl analysis is correct. It is proved that the method used to # measure the Hydrodynamic diffusion-dispersion coefficients of the Lou soil is feasible.更多还原
