| 摘 要： | 地面电场仪测量数据准确性和一致性会直接影响到其在研究区域大气电学和进行雷电预警工作的应用准确度。通过模拟理论计算和实际观测数据进行的统计对比分析，指出了电场仪自身高度和周围环境均会产生测量误差，不同高度上的电场测量值与地表处均呈现出一定的正相关性。在晴天和雷暴两种天气情况下，由于产生地面电场的电荷源不同，提出了分别利用统计和线性拟合对这两类测量数据进行修正的方法。

| Abstract: | The accuracy and consistency of measuring data will directly affect preciseness of their application on the research on regional atmospheric electricity and the lightning warning. By using simulative calculation and comparing the measuring data of atmospheric electric field, this paper points out that the measurement error may be produced by the height of electric field mill and its ambient environment, and there is a certain positive linear correlation between the electric field at different height and that at surface. Because the charge sources generating atmospheric electric field under sunny and thunderstorm condition are different, the statistical and linear fitting methods are proposed to revise the measuring data, respectively. |
