LISST-1OOX粒度分析仪在石角站的应用研究

摘要

LISST-100X （C） which uses laser diffraction technique is a relatively advanced sediment analysis instrument. In order to check the performance of LISST-100X in practical application and provide the reference for application in Guangdong province, many experiments were conducted in hydrometric station of Shijiao. The problem whether LISST-100X is suitable for measurement and analysis of suspended sediment is verified while the performance on sediment concentration and particle size analysis are discussed. Then the relationship between VL/L and Kg/m3 is determined. This research can provide reference to the application of LISST-100X in Guangdong.%LISST-1OOX（C型）采用激光衍射技术，是目前比较先进的泥沙分析仪器，方便快捷、操作简单。为了检验其在实际应用中的性能，特将北江石角站作为实验站点进行了多次试验，对其是否适宜进行悬移质泥沙测验与分析进行了验证，分析其在含沙量、颗粒分析等方面的性能，建立了单位（VL／L）与常规测沙（Kg／m^3）的转换关系，为该仪器在广东的推广使用提供参考。
