摘　　要：我们利用自行研制的“光学悬浮沙粒径谱仪”对长江口悬沙颗粒进行了现场测量,同时作了现场采样,经华东师范大学河口海岸国家重点实验室分析,分析结果与仪器现场测量结果进行了对比,结果表明,两种方法得到的平均粒径和悬沙浓度基本一致。By using Optical Suspended Sand Size Spectrometer made by National Ocean Technology Center, in situ measurement and sampling of suspended sand in Yangtze River Estuary was carried. The laboratory alalysis samples was carried by State Key Laboratory of Estuarine and Coastal Research East China Normal University. Compared the analysis results with in situ measurement results, the conclusions gained by two kinds of methods for average grain size and concentration of suspended sand are same.
