摘要
阐述了利用微机对大气电场及麦克斯韦电流密度进行实时多路长时间记录，显示的原理、操作方式及编程。在野外观测的基础上首次获得了电场、电流密度的同步数字化资料，实现了电场、电流密度观测记录的自动化。该系统测量信号以模拟形式实时连续滚动显示在ＶＧＡ显示器上，数字化信号实时存储在计算机硬盘上，记录后的数据可再处理。
This paper describes the principle, method and programming of a long duration, multi-channel PC recording and real-time display system for measuring atmospheric electric field and Maxwell current density Through field experiment, the synchronous digital data of field and current density were recorded automatically The measured signal is continuously displayed on VGA monitor with analog form Digital signal is stored on hard disk in real-time for later processing or display
