静电场描绘的一种改进方法

摘要

理解模拟实验法的适用条件，对于给定的电极，能用模拟法求出其电场分布，加深对电场强度和电势概念的理解。对实验结果分析误差来源，改进实验数据的求算方法，本文介绍的是使用算术平均法作出等势线，描绘静电场。与课本中的方法进行比较，结果误差更小，更准确的描绘了静电场的分布。%Understanding the applicable conditions simulation method,for a given electrode,which can be ob-tained electric field distribution simulation method,the electric field strength and deepen the understanding of the potential of the concept. Sources of error for results analysis,improvement and experimental data calculation method,described in this article is to equipotential lines depict the electrostatic field using the arithmetic aver-age method. The method for comparison with the textbook,resulting error is smaller,the more accurate picture of the distribution of the electrostatic field.
