由河海大学电力工程系卢永生副教授负责的研究小组,在 GDY-1型和 NSY-1型光电颗粒分析仪的基础上,经多次改进和试验,研制成功 NSY-2型宽域粒度分析仪,于1988年12月6日在南京通过了由水利部水文司组织的鉴定。NSY-2型宽域粒度分析仪可作为河流泥沙分析的常规仪器,也可用于石油、地质、冶金建筑、电力等部门的粉末材料粒度分析。鉴定认
Based on the GDY-1 and NSY-1 Photoelectric Particle Analyzer, the research team led by Prof. Lu Yongsheng, Associate Professor of Electrical Engineering Department of Hohai University successfully developed NSY-2 wide-area particle size analysis Instrument, passed the identification organized by the Hydrology Department of the Ministry of Water Resources on December 6, 1988 in Nanjing. NSY-2 wide-area particle size analyzer can be used as a conventional instrument for river sediment analysis, and can also be used for particle size analysis of powder materials in petroleum, geological, metallurgical construction and electric power sectors.
