摘　　要：本文通过对国产塞曼原子吸收分光光度计一段时间的使用与实际测量后,着重介绍了两个考察仪器性能的实验,一是开机不预热的长时间静态基线稳定性实验;二是长时间、多元素、混合测量的数据重现性实验。特别是实验二,是8小时的连续工作、多任务多元素的混合测量、关机后第二天的继续测量、以及若干天后的再次测量等,而确立的有针对性的考察数据能否稳定重现的实验,能够反映用户在实际使用中诸多常见的工作情况,具有一定的参考价值,从一个侧面反映了现有国产塞曼原子吸收仪器的可靠性能,得到了满意的结果。In this article we describe two experiments to test the performance of domestic brand Zeeman Atomic Absorption Spectrophotometers（Zeeman AAS）.The first experiment deals with long-term baseline stability when instruments are used immediately after power on without a warm-up period.The second experiment deals with reproducibility of multi-element simultaneous measurements over extended use in one day and in the long term.For the second experiment,we emphasized on testing the instruments for reproducibility in multi-task,multi-element simultaneous measurements repeated over eight consecutive hours,and repeated on the following day or a few days later after power off. These validated performance tests adequately address the practical questions and concerns of the users of domestic brand Zeeman AAS currently on the market.
