摘要
叙述中国和美国分别提出的河流泥沙颗粒分析的技术要求,由此研制了NSY-2型宽域粒度分析仪,该仪器的性能测试方法及测定的结果,说明仪器达到了河流泥沙颗分技术的要求.
This paper consists of two points about fluvial-sediment analyzers : 1. Some suggestions from the P. R. C. side and the U. S. A. side about the specifications of fluvial-sediment particlesize analyzers which is the basis for the development of newtype analytical instruments. 2. a measuring method of analyzer performance and measured results . The analytical results show good agreement with the specifications.
