低频无线通信的综述与探索

A Summary and Probe for Low Band Radio Communication

从可靠的资料，综述了自１９３５年以来，前苏联、英国、美国和南非为代表的低频无线通信发展史。并以高、深电磁近区场理论为依据，小结了前苏联和我国在超长波和长波频段使用无线信道的异同，提出了岩石波导的新概念。期望２１世纪中华民族在从矿井综合业务网到军用长波地表通讯系统，直至山区和沙漠定向设备中作出应有的贡献。

The history of low band radio communication from 1935 to now in America, former Soviet. South Afirica, Britain, etc., is summarized on full and exact data. According to the new electrimagnetic close field theory, the differences of radio channel between ultra-long-wave band and long-wave band in former Soviet and China are brief summarized. The concept of soil waveguide is proposed. At last, the contributions of Chinese to integrated services network of mine field, military long-wave communication system and beam equipment for mountain and desert area communication in 21th century are forecasted.
