为了有利于地震战线开展基础地震学方面的研究,给全国地震观测第一线同志们提供一些学习的参考读物,我们计划编译一套地震观测研究系列文集,该文集的第一集《震相与地球内部结构的测定》一书已经出版。至今,人们对于地球内部结构的认识,主要来源就是对于地震波各种震相的研究,地震波能够在地球内部传播,因此,给我们带来了地球内部结构的信息。目前,对于这个认识及 In order to facilitate the research on basic seismology in the earthquake front and to provide some learning reference materials to the comrades in the field of seismic observation in the nation, we plan to compile a series of anthologies for seismic observation research. The first episode of “ The book ”Determination of the Earth’s Internal Structure" has been published. Up till now, the main source of people’s understanding of the internal structure of the Earth is the study of various seismic phases of seismic waves that can propagate inside the Earth, thus giving us information about the internal structure of the Earth. At present, for this understanding and
