模拟静电场实验的误差分析与研究

Analye and Research for Error of The Exeperiment of Describing Electrostic Field

用A类标准不确定度方法、一元线性回归方法、二元线性回归方法分别处理稳恒电流场模拟静电场中得出的实验数据,通过理论分析与数值比较,讨论了三种方法的特点。处理结果表明:二元线性回归法是一种更为精确的数据处理方法,该方法是现行教材中未使用过的数据处理方法,在教学中推广使用,教学效果较好。

In this paper, accidental error method and the unitary linear returning method and the duality linear returning method are used to deal with the experimental data based on the experiment of describing electrostatic field simulated by steady current field. The accuracy of the three methods is confirmed by comparing the numerical results. The results show that the duality linear returning method which hasnt been used in materical at present and is importantly introduced in this article is good.
