  1. The main results were as follows : ( 1 ) due to their different working principles, the measured result of clay content by laser particle - size analysis was lower than that by using pipette and sieve analysis. the classification results of soil texture by using these two methods agreed well with each other

    主要結論如下： （ 1 ）由於激光法和吸管法原理的不同，激光法測得的粘粒含量較吸管法低，但是在土壤質地分類上，激光法和吸管法的結果基本一致。
  2. A preliminary study was carried out on the method of acquiring parameters for soil dual - porosity model and the analysis for the simulation of soil nitrate leaching by dual - porosity model. the feasibility and experimental conditions of soil particle size analyzing by the laser particle - size analysis was discussed, based on the comparison results of nine soil samples by the laser particle - size analysis and traditional pipette and sieve analysis

    本文初步探討了土壤兩域模型的參數獲取方法及兩域模型應用於土壤硝酸鹽淋洗的模擬分析，為進一步研究優先流以及分形理論在土壤溶質（包括養分）運移研究中的應用打下基礎，以更準確地模擬和預測農田土壤硝酸鹽的淋洗，為農田水肥優化措施提供依據。
