摘　　要：文章以密度计法测土壤机械组成为切入点,探讨了分析过程中一些重要影响因素及注意事项,分析了样品均匀性、样品酸碱性的判别、分散剂校正、分散时间、分散剂添加顺序等因素对试验结果的影响,为试验的顺利开展提供了技术参考。同时,文章也针对性地提出对机械组成试验分析方法不同的看法。In this paper, some important influencing factors and matters in the process of soil particle distribution test by densitometer were analyzed. The effects of sample uniformity, sample acidity and alkalinity discrimination, dispersant correction, dispersion time and dispersant addition sequence on the test results were analyzed, which provided a technical reference for the smooth development of the test. At the same time, different views on soil particle distribution test and analysis methods are also put forward.
