求翻译：The exchangeable Cu and the pH were determined in an extract of 0.1 M KNO 3 (at a 1:2.5 soil:liquid ratio), and the soluble Cu was determined in a water extract (at the same soil:liquid ratio)following reciprocal shaking for1h,centrifugation at 9000 rpm for 10 min and filtration through 8-µm paper filters (KNO 3 extrac是什么意思？ 待解决

可交换的Cu和pH值（ 2.5土：在液比1 ）测定在0.1M的KNO 3的提取物，以及可溶性铜是在一个水提取法（在相同的土壤：液比）以下往复振荡

可更换式CU和pH值决定了在一个解压的kno3 0.1m(1:2.5土壤:液体比率)和速溶CU是确定在一个水提取(在同一土壤:液体比率)以下相互握手,1h,在9000转 分转速centrifugation为10分钟和过滤通过8μm过滤纸(kno3extract)或0.2μm注射器过滤器(水提取)。
