摘　　要：介绍了组织全国多个行业102家实验室参加茶叶中联苯菊酯、毒死蜱残留量的测定能力验证的情况。选用自然基体测试样品,分别采用F检验和t检验法检验样本的均匀性和稳定性,采用稳健统计技术对试验结果进行了分析。对残留量测定的关键技术进行了讨论。A schem of proficiency testing by interlaboratory comparisons involved 102 laboratories for the determination of bifenthrin and chlorpyrifos residues in tea was presented. The tea that contained bifenthrin and chlorpyrifos were selected as test materials, and F - test and t - test was used to check the homogeneity and stability of test materials. The robust statistical technique was used to analyze the test results. The critical points of residues determination were also discussed.
