摘要/Abstract

摘要： 进口激光粒度分析仪在荆江河段泥沙颗粒级配分析中应用了7 a，大大提高了生产效率，减轻了劳动强度。随着国产激光粒度分析仪的崛起，其在性价比、技术服务上相对进口分析仪更具优势。国产百特BT3000激光粒度分析仪，具有颗粒级配分析功能，基于该分析仪，利用收集的长江荆江干流及四口水系8个基本水文站一个完整年度的悬移质泥沙配置成的粗、中、细沙型样品，采用碳酸钙标样、玻璃珠标样，对其基础参数进行适用性优化，开展了准确性和稳定性等测试分析。结果表明：各项技术指标均能满足有关规范的要求，已获投产应用。研究成果可为国产激光粒度分析仪的投产应用提供参考。

Abstract: The imported laser particle size analyzer has been used for 7 years in the grading analysis of sediment particles in Jingjiang River reach, which greatly improves the production efficiency and reduces the labor intensity. With the rise of domestic laser particle size analyzer, it has more advantages on cost performance and technical service. Domestic BETTER BT3000 Laser Particle Size Analyzer has the function of particle grading analysis. Based on the analyzer, its accuracy and stability were tested and analyzed by using the coarse, medium and fine sand samples of suspended sediment from eight hydrological stations of the main stream and four tributaries in Jingjiang Reach of the Yangtze River in a complete year. The applicability of basic parameters was optimized by using calcium carbonate and glass beads standard sample. The results show that all the technical indicators can meet the requirements of relevant specifications and the analyzer has been put into operation. The research results provide reference for the production and application of domestic laser particle size analyzer.
