摘　　要： [目的]通过使用标准物质及实验室人员比对实验,保证商品煤检测结果的质量。[方法]按照国际、国家标准对标准物质及样品进行检验,利用t检验法对标准物质检验结果的显著性差异进行验证;选择同批次同一煤样品进行人员比对实验。[结果]标准值与检测平均值之间无显著性差异;同批次同一煤样品人员比对实验的检测结果非常一致,完全满足相应标准的再现性要求。[结论]本实验室的分析测试具有很好的准确度,所出具的检测数据具可信性。 standard substance and personnel parallel experiments were taken to ensure the quality of testing results of commodity coal. The salience diversity of inspecting results on standard substance were validated by t testing method to inspect standard substance and samples according to the international and national standards. Personal parallel experiments were taken to select the same sample of the same batch coal. It shows that there is no notable diversity between the standard value and inspecting average value. And the inspecting results on the same sample of the same batch coal between the persons are much closed, satisfying the reappearance request of the corresponding standards. Our laboratory has the ability to take the test with good accuracy and exact and reliable exoeriment data.
