从数据统计学处理谈标样的组织与管理

A Discussion on the Organization and Management for Certification of Geological Reference Materials Based on Data Processing

研制天然物质化学成分的标准样品是现代地球化学工作的重要内容之一。据1984年K.Govindaraju报导,目前国际上已有170多种岩石和矿物标准样品,其中有我国的8个水系沉积物和2个超基性岩标样。这些标准样品在验证大量地质样品分析数据的可靠性。

This paper deals with the organization and management for certification ot geological reference materials from the point of view of data processing.The selection,collection and preparation of samples,verification of homogeneity,collaborative analysis and evaluating samples from compiled data,as well as the approaches of evaluation are discussed.In order to obtain the best approximation of the"true"value,the scientific management in collaborative analysis should be emphasized.
