摘　　要：为解决传统的泥沙颗粒分析方法普遍存在的自动化程度低、手工操作环节多、分析时间长、成果精度受人为因素制约等问题,利用适用于实验室测试分析的激光粒度分析技术、动态泥沙粒形分析技术以及适用于野外在线测量的在线粒度分析技术等全自动颗粒分析技术,构建了一种新型的高自动化水平的黄河水文泥沙颗粒分析技术体系。该体系能以数据、图表等形式快速、精确地给出泥沙的粒度、粒形信息,实现了泥沙粒度分析的野外在线作业,丰富了对泥沙颗粒形貌特征的认识,拓宽了水文在泥沙领域的服务功能。To solve the problems of traditional sediment grain size analyzing methods such as low degree of automation,many manual operation links,long analyzing duration,result precision conditioned by human factors and so forth,the automatic grain size analyzing technologies were used,such as Laser Grain Size Analyzer (MS2000)and Particle Image Analyzing Technology(QICPIC)for lab,Online Particle Analyzing Technol-ogy(OPUS)for field observation and so on,as a result to construct a new-type Yellow River hydrological sediment particle analyzing system with high degree of automation which can precisely show sediment grain size and particle shape information and widen hydrological service function in sediment research field.
