盘式吸渗仪吸渗率计算方法比较（Comparison among Permeability Methods of Disc Infiltrometer）
吸渗率 盘式吸渗仪 计算方法
2009/9/25
选用盘径为5cm和15cm的盘式吸渗仪，对杨凌塿土（粘土）和神木砂黄土（砂壤土）两种质地的土壤在0、－3、－6、－9、－12cm 水头5种负压下进行了室内吸渗实验，分析了不同盘径和负压对累积吸渗量的影响；并选用4种吸渗率公式对这两种质地土壤吸渗率进行了计算，以Vandervaere法为参考方法对该4种方法的适用性进行了分析。结果表明，在相同的时间内，两种土壤5 cm盘径下的累积吸渗量均大于15 c...
