河流泥沙颗粒分析的要求及指标测试

Needs and Indices Measurement of River Sediment Size Analysis

以河流泥沙颗粒分析为例，说明各具体的专业颗粒分析技术都有一些原则的要求；颗分仪器的设计必须考虑这些要求；所研制的新仪器新方法必须与该领域里传统的公认的方法具有可比性，有一系列比测的方法及指标。

Sediment size analysis for each field,taking river sediment as an example,has its own principal needs and the analyzer designing must take these needs into consideration.New analyzers and methods must be comparable to the traditional methods.A series of comparative methods and indices have to be presented in order to control the analyzing quality and maintain the continuity of historical information.
