颗粒分析试验方法的论证

摘要

Two kinds of methods were applied for particle analysis tests,which were non-standard method and standard method.Then, theories and limits of hydrometer method were presented, and formulas of the two methods were representatively analyzed.Through tests on the soil,the differences of the two methods and reasons were obtained in this paper.Meanwhile, through quantitative methodology, the differences on clay particle content which were obtained from the two methods were analyzed.%文章介绍了颗粒分析试验的2种方法,非规范法(常用方法)和规范法.阐述了密度计法的原理及其局限性,讨论了2种试验方法各自所用公式的适用性.通过试验,得出了2种方法的差别,并分析了其中的原因,同时,从定量的角度分析了2种试验方法所得粘粒含量的差别.
