本文根据大量的实测数据和实验结果,对地传广播(“ETR”——earth transmit radio)的一些基本问题作了理论和实践的阐述及研讨。此方式可因地制宜地取代有线广播传输方式,可节省大量人力、物力、、财力,受到广大农村欢迎,具有一定的社会效益和经济效益。 Based on a large number of measured data and experimental results, this paper elaborates and discusses some basic problems about Earth Emissions Transmission (ETR). This method can replace the cable broadcast transmission method according to the local conditions, which can save a lot of manpower, material resources and financial resources. It is welcomed by the vast rural areas and has certain social and economic benefits.
