基于电磁辐射理论基础，对昌平地震台(3套)、十三陵地震台(1套)不同生产厂家和型号的4套电磁波仪观测数据进行对比分析。研究表明，各种仪器观测数据变化趋势大致相同，显示出较好的一致性，但数据产品的产出格式需加强规范，以便应用与共享。

Based on the theoretical basis of electromagnetic radiation, we have set up in the Changping the different types of seismic waves four sets of instrument observation data were compared and analyzed. Studies have shown that most of the instruments similar trends in observational data, showing good consistency, but the output format for data products need to be further standardized in order to better use and sharing.
