|
摘要
介绍了美、俄超低频对潜通信系统,提出除军事用途,超低频通信系统最有前景的方向是进行电磁监测,俄ZEVS系统的研究实验揭示了SLF电磁波异常与将要发生地震的一些初步规律,地震与观测的电磁场异常和视电阻率的变化有较好的对应性。利用它可以研究地下电阻率结构和空间电磁场;研究地震等引起的电磁场异常变化;用于探测地壳结构和地下资源、发现核废料、环境研究以及地震的监测和预报。具有广阔的应用前景和发展潜力。
This paper introduces American and Russian SLF (super low frequency) transmitting station .Electromagnetic waves in SLF frequency band can be transmitted by source -controllable powerful generator. The artificial signals can be measured in a quite large area on earth surface for investigation of the space electromagnetic field and crust conductivity structure. The signal can penetrate down to several dozens kilometers depth, so that it is widely applied to the reconnaissance of resources, detection of subsurface nuclear waste, environmental research, as well as the monitoring and prediction of earthquake. The experiment study by ZEVS indicated that the method is a useful tool to study electromagnetic anomaly caused by earthquake and to probe the subsurface resources.
