铝电解企业实验室标准物质期间核查方法探讨

Discussion on the Period Check Methods of Normal Substance in Electrolysis Aluminium Enterprises Laboratory

介绍了铝电解企业实验室标准物质定期核查的几种统计方法,利用t检验法、F检验法或En数法对标准物质进行期间核查,确保分析检测数据准确可靠。经过大量数据证明,利用以上三种统计方法开展核查,科学合理,满足质量控制要求,适合铝电解企业实验室推广应用。

This paper introduces several statistic methods of period checks of normal substance in electrolysis alumin- ium enterprises＇ laboratory,which using t inspecting method＇, F inspecting method or En number method to carry out the period checks to the normal substance, and ensuring the veracity and reliability for analyzed data. A number of data show that the period checks using the three statistic methods mentioned above can meet the qualiy controlling re- quirements, and they are suitable for the popularization and application of aluminium electrolysis enterprises＇ labora- tones.
