摘　　要：粒度分布测量过程中,由于各种原因,使得测量结果不能再现。为了让测量准确,减轻测量、分析人员大量烦琐的计算、制表、绘图等工作,介绍了沉降式粒度分布仪的测量原理和测定方法,对具有代表意义的黏土进行粒度分布测定,通过大量的实验对粒度分布测量中存在的再现性进行了分析,得出了在粒度分布测量过程中能够体现其再现性的好的方法。Results could not recur for many reasons during the measurement of particle distribution. In order to attain accurate results and lighten the excessive tasks of measurer and analyzer, the principles and methods of sediment size distributive instrument were introduced in this paper. The repeatability of measurement for clay particle distribution was analyzed by a mass of experiments, and some advanced methods were presented for accurate measurement of particle distribution.
