作为我国全国区域化探扫面样品分析一级监控用的首批水系沉积物标准参考样GSD1～8系列,历经三年研制,于1983年7月通过了国家级鉴定会,对五十多个元素提出了推荐值或参考值(以下均简称为定值),全国有41个实验室的上千名分析工作者为此做出了贡献,共对68个元素和成份完成了五万多个测定。加拿大地质调查所和法国地质与矿产研究所也提供了数据。投入的分析手段多达26种11类(见表),参与中子活化分析的有中科院原子能所、高能所及本所。从表可见,各类方法所完成的工作量,就元素数量而论,中子活化占有优势,三个中子活化实验室已提交36个元素的结果,占已定值元素总数(54个)的66.7％。
As the first batch of GSD1 ~ 8 series of sediment standard reference materials for the monitoring and analysis of China’s regional chemical exploration surface samples, after three years of research and development, in July 1983 passed the national appraisal meeting, more than 50 The elements make recommendations or reference values (hereinafter referred to simply as setpoints), and thousands of analysts in 41 laboratories throughout the country contribute to this by completing more than 50,000 in 68 elements and components Determination. The Canadian Geological Survey and the French Institute of Geology and Mineral Resources also provided data. As many as 26 kinds of 11 kinds of investment analysis methods (see table), there are Chinese Academy of Sciences Atomic Energy Institute, High Energy Institute and the firm involved in neutron activation analysis. As can be seen from the table, the amount of work done by each method, in terms of the number of elements, neutron activation has an advantage. The three neutron activation laboratories have submitted the results of 36 elements, accounting for the total number of elements (54) Of 66.7%.
