摘　　要：根据砝码磁性参数的测量原理,针对磁性测量中示值稳定性的影响量进行分析,提出影响砝码磁性参数测量中示值稳定性的关键影响量.采用最大称量5.1 g、分辨率0.1μg的磁化率计进行砝码磁性测量,测量过程中分别同步测试振动的变化和环境磁场的变化,通过实验数据分析,验证了环境磁场的波动是影响砝码磁性测量的关键影响量.Abstract：According to the measurement principle of weight magnetic parameter, the influence of reading stability for measuring magnetism is analyzed, and the key influence of reading stability is presented in the measurement process. The magnetism of weight is measured by the magnetic susceptometer with capacity of 5.1 g and resolution of O. 1 μg. At the same time the change of environmental vibration in the laboratory and the fluctuating of ambient magnetic field are measured respectively. The experimental results show the fluctuating of ambient magnetic field that is the key influence of weight magnetism measurement.
