摘要
研究了不同试验因素 (包括图像分辨率、土壤切片定向性、分析区域大小等 )对孔隙结构图像分析结果的影响以及试验误差 ,并简要介绍了用于分析土壤孔隙结构的土壤切片及数字图像的制备技术。结果表明 :不同试验因素对分析结果均会产生一定的影响 ,试验误差约在 1 0 %。
This paper introduces briefly techniques for preparing soil sections and digital images, with emphasis on influences of various experimental factors, such as image resolution, orientation of soil section, analyzed area and so on on the analysis of pore structure. Experimental results obtained by this method are subject to a deviation rate of 10 %?1/4HT?1/2. The results showed that, for making analytical results reliable and comparable, it was very important to keep the experimental factors replicable and stable because any variation in the experimental factors could influence the analysis of pore structure.
