摘　　要：介绍了北京市67个检测机构回弹法测定混凝土强度能力验证的测试情况。能力验证过程中,对检测机构的检测结果采用稳健(Robust)统计技术处理,减少了极端结果对平均值和标准偏差的影响。同时对统计分析的设计过程、能力验证统计结果及各机构的检测能力进行了分析。Serials of measures were taken to make sure the uniformity of test samples before ability certification of 67 witness institutions of testing construction quality for testing concrete strength by rebound method in Beijing. During the process of ability certification, robust statistical techniques were used in anglicizing testing results, which induced the infection on average value and standard error because of extreme data. At the same time, the designed process of statistic analysis, test statistical results and ability certification of witness institutions were presented.
