摘　　要：为提高四川省检测实验室中土壤有效态微量元素的检测能力,本文以锌、锰、铁、铜为能力验证的检测对象,将参加活动的109家实验室的检测结果进行对比,并采用稳健统计法进行分析和评价。结果表明:(1)91~94家实验室一次性检测结果为满意,通过率为86.2%~87.9%,稳健变异系数CV均小于9.7%,数据较为集中,检测能力总体水平较好;(2)部分检测实验室通过对问题的及时发现和改进,有效地提升了质量技术水平。In order to improve the detection ability of soil available trace elements in testing laboratories in Sichuan Province,this paper takes zinc,manganese,iron and copper as test objects for capability verification,compares the test results of 109 participating laboratories,and adopts robust statistical method for analysis and evaluation.The results showed that:(1) The one-time test results of 91~94 laboratories were satisfactory,the pass rate was 86.2%~87.9%,and the robust coefficient of variation CV was less than 9.7%.The data were relatively concentrated,and the overall level of detection ability was good.(2) Some testing laboratories have effectively improved the quality and technology level through timely discovery and improvement of problems.
