摘　　要：为了提高监测仪器比对结果的可比性,选择场强稳定且不受外界电磁环境影响的场所开展比对是必要的。本文分析总结了在标准电波暗室里开展选频射频电磁辐射监测仪器比对测量的经验和做法,通过比对,暴露出日常工作难以发现的问题,提出监测仪器期间核查相关建议;在稳定的、标准的电磁场环境开展比对,为电磁环境监测仪器比对提供一种新做法。In order to improve the comparability of the comparison results of monitoring instruments,it is necessary to select a place where the field strength is stable and is not affected by the external electromagnetic environment for comparison.This article analyzes and summarizes the experience and practices of conducting frequency-selective radio frequency electromagnetic radiation monitoring instrument comparison-measurement in a standard anechoic chamber,and finds out some problems that are difficult to detect in daily work.This paper also proposes suggestions for monitoring instrument verification during the monitoring period.Conducting comparisons in a stable and standard electromagnetic field environment could provide a new practice for electromagnetic environment monitoring instrument comparison.
