砝碼磁化率對質(zhì)量測量過程的影響

根據(jù)砝碼磁性參數(shù)的測量原理,針對磁性測量中示值穩(wěn)定性的影響量行分析,提出影響砝碼磁性參數(shù)測量中示值穩(wěn)定性的關(guān)鍵影響量.采用zui稱量5.1 g、分辨率0.1μg的磁化率計行砝碼磁性測量,測量過程中分別同步測試振動的變化和環(huán)境磁場的變化,通過實驗數(shù)據(jù)分析,驗證了環(huán)境磁場的波動是影響砝碼磁性測量的關(guān)鍵影響量.

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.
