| 摘 要： | 本文对力学室一等质量实验室的26、27、32三个公斤工作基准砝码的稳定性误差分别作了分析。经过对历年的检定记录和中间核查的分析汇总，得出各个公斤工作基准的稳定性误差，采用多个砝码多次全组合测量，利用最小二乘法计算出这三个公斤工作基准砝码之间的质量差值，找出它们的稳定性误差的变化趋势。

| Abstract: | this text analyses the stability errors for No.26 No.27 & No.32 kilogram benchmarks. Through the classification statistics of annual verification certificate, we get the stability errors of those weights. If several weights have been calculated by the multiple combination of measurement and stability errors have been calculated by least square method, we may draw the graph of variation of stability errors. |

| Keywords: | standard for kilogram the stability errors variation of stability errors |
