中文摘要: 基于泥沙的沉降特性，本文利用超声回波技术，提出了一种新的泥沙颗分方法，经对沙样的实际比测表明，超声颗分具有重复性好，无接触测量，连续自动采样且不受泥沙色度的影响等特点，为泥沙的颗粒分析提供了新的途径。
Abstract:Based on the principle of sand particle falling, a new method using the ultrasonic echo technique has been introduced for analysing particle sias. By means of doing many experi-ments, analysing and comparing the experiment data with the real value, we obtain some re-sults, and prove the imagination of automatic analysis of sediment grain size with ultrysonic.It seems feasible to analyse particle sias with ultrysonic.
