江西省自1967年陆续开展悬移质泥沙颗粒级配分析工作以来,河流、湖泊的颗粒分析方法为沉降法中的粒径计法,该方法工作步骤繁多、时效性较差、重复性不好,且其分析范围有限,已达不到水利部关于颗粒分析精度的新要求.激光粒度分析仪(马尔文MS2000型)具有速度快、精度高、成果质量佳、稳定可靠、误差小的特点,能满足颗粒分析及资料整编的精度要求,能较好地适用于本省河流颗粒分析工作,大幅提高成果的精度,极大地减轻劳动强度,节省工作时间.本文主要介绍激光粒度仪在江西省部分河流颗分站的使用、比测及分析情况.

Since the analysis of suspended sediment particle size distribution of Jiangxi province started in 1967, the particle count method of the sedimentation method was adopted in the particle size analysis for rivers and lakes. The method cann't reach the ac-curacy requirement of particle analysis for the Ministry of Water Resources because of too many steps, narrow application range and poor time effectiveness and repetition. Laser particle size analyzer (Malvern MS2000) has many feathers such as high speed, high accuracy, good results, stabilization and little error, so it can reach the requirement of particle size analysis and data reduc-tion accuracy, applied to the particle size analysis for the rivers in Jiangxi province in order to remarkably improve the results ac-curacy, greatly reduce labor intensity and save working hours. This paper mainly introduces the usage, comparative observation and analysis of the laser particle size analyzer in the particle size analysis stations of some rivers in Jiangxi province.
