目前地球上有成千上万个地震台,但它们都是接收地震波的地震台。建议建立一种新型的地震台,这种地震台用人工的方法不断地向外发射地震波,照亮需要研究地区的地下结构,研究特定的科学问题。建立地震发射台的核心问题是选择合适的人工震源,近年来出现的绿色环保震源,以及现代信息处理技术的发展,使得建立照亮10万km^2(深至Moho面)地区地下结构的地震发射台已经完全是可能的。
There are many seismographic stations in the world, that receive seismic waves generated by earthquakes. We proposed the establishment of a new type of seismic station, which continuously transmits seismic waves with artificial source. By use of seismic wave generated by the transmitted stations we can obtain the image of deep Earth. The key problem of the transmitted station is to find the suitable artificial seismic source: powerful, green and clear sources. With the development of air-gun technique and information theory, it is possible now to obtain the image of a 100 000 km^2 in spatial coverage and 40 km in depth ( deep to Moho) by use of the transmitted seismic stations.
