砝碼磁性的測量及不確定度分析
黨正強 薛靚中國測試技術研究院,四川成都610021摘　要:隨著電子天平的廣泛采用，因為大多數電子天平都采用電磁平衡原理，砝碼與電子天平之間將產生相互磁力作用，了解砝碼的磁性，降低砝碼磁性對電子天平的作用，越來越引起我們的重視。本文詳細闡述了國際建議推薦的幾種砝碼磁化率的測量方法，最后以磁化率計法為例介紹了砝碼磁化率的測量原理、方法及不確定度分析。了解砝碼的磁性，即了解砝碼與電子天平之間產生的相互磁力作用，故有利于提高稱量結果的準確性。[著者文摘]

Measurement of weight susceptibility and analyzing of uncertaintyDANG Zheng-qiang, XUE Liang National Institute of Measurement and Testing Teehnology, Chengdu 610021, ChinaAbstract:Along with extensive using of electronic balances, the volume magnetic susceptibility of weights is very regarded.Ibis paper describes volume magnetic susceptibility of weights and the importance of its testing. We also introduce the method of how to measure the weight susceptibility , and analyze uncertainty of measurement. It＇s very useful to enhance the precision of measure results when we understand the volume magnetic susceptibility of weights.[著者文摘]
