摘　　要：近年来,我国中短波广播获得了良好的发展效果,受现代信息科技影响,其发展空间不断拓展,但发射台实际运行的过程中受电磁干扰影响较大,这在一定程度上会弱化中短波广播效果,不利于促进发射台稳定运行。文章首先对中短波广播简要介绍,然后总结电磁干扰内容及类型,最后提出电磁干扰控制的有效措施。In recent years, the medium and short wave broadcasting in our country has obtained good development effect, which is inf luenced by modern information technology, and its developing space is continuously expanded, but in the actual operation of transmitting station, it is greatly affected by electromagnetic interference. To some extent, this will weaken the effect of short-wave broadcasting, which is not conducive to promoting the stable operation of the transmitter. In this paper, the medium and short wave broadcasting is introduced brief ly, then the contents and types of electromagnetic interference are summarized. Finally, the effective measures of electromagnetic interference control are put forward.
