替代法測量微安表內(nèi)阻的不確定度分析
王吉有 原安娟北京工業(yè)大學(xué),北京100022摘　要:在測量微安表內(nèi)阻的眾多方法中，替代法是最簡單的方法。本文全面分析了影響測量結(jié)果不確定度的因素，求出了實驗測量的最佳條件，計算了普通儀器組合下測量結(jié)果的相對不確定度。[著者文摘]

THE UNCERTAINTY ANALYSIS OF MEASURING INNER- RESISTANCE OF MICRO - AMPERE - METER WITH THE SUBSTITUTE METHODWang Jiyou ,Yuan Anjuan Beijing University of Technology, Beijing, 100022Abstract:Among the methods of measuring inner - resistance of micro - ampere - meter with the substitute method is the most simple one. In this paper, the parameters of affecting the uncertainty of the measured result are analyzed. The best conditions of the measurement are obtained. The uncertainty of the measured result is caculated in general laboratory.[著者文摘]
