为了确定水中钚的分析方法的精密度,1987年6月至7月国家环保局委托原子能院组织了核工业部五家实验室,对统一制备的四种水平的水样,按本方法操作程序进行放化分析。而后对各实验室的分析数据先后用格拉布斯法,科克伦检验法,狄克逊检验法进行异常值的检验。计算出每个水平的总平均活度值m,重复性(γ),再现性(R)。经计算判 In order to determine the precision of analytical methods for plutonium in water, the State Environmental Protection Administration commissioned the Atomic Energy Agency to organize five laboratories of the Ministry of Nuclear Industry from June to July 1987. Four uniform levels of water samples were prepared according to the procedures of this method Radiochemical analysis. Then the analysis of the laboratory data were used Grubbs, Cochrane test, Dixon test for abnormal values. The total average activity value m, repeatability (γ) and reproducibility (R) were calculated for each level. Judged by calculation
