利用比重计法与传统的吸液管法分析试样在粒度级配曲线、定名、粘粒含量、不均匀系数、中值粒径等方面的差异 ,发现两种方法的结果基本上是一致的。但比重计法易受容器的大小形状的影响 ,如容器的有效深度过小 ,则会造成比重计法所测得的试样粘粒含量偏高 The results of the two methods are basically consistent by using the hydrometer method and traditional pipette method in analyzing the grading curve, naming, clay content, non-uniform coefficient and median diameter of the sample . However, the hydrometer method is susceptible to the size and shape of the container. If the effective depth of the container is too small, the clay content of the sample measured by the hydrometer method will be high
