摘　　要：通信车被复线具有取材方便、性能稳定、抗老化等诸多优点,但是其抗干扰效能较差,受外界电磁环境影响较大。特别是在通信车附近,通信车电子设备产生的复杂电磁环境对被复线形成的场线耦合干扰尤其严重。从理论上分析了被复线受外界电磁场影响产生场线耦合干扰的原因,并提出了减小被复线上场线耦合干扰的相应方法。The field telephone lines loaded in the communication vehicle are not only cheap for their materials but also with steady characteristics and good aging. Nevertheless, the electromagnetic immunity to external waves is beyond the acceptable consideration. Especially, field telephone lines around the communication vehicle may be interfered severely because the external complex electromagnetic fields illuminating, which are mainly oriented from the equipments loaded in the communication vehicle. In this paper, the causation of the field -to -line coupling on the field telephone lines is analyzed,and then some appro- priate solutions are presented.
