引言长期以来，我们主要依靠模拟记录的地震图来研究地球结构和确定地震参数。随着地震科学的发展，人们需要对地震的震源过程及其机制有更进一步的认识，要求提供大动态、高分辨率和高精度的地震数据。电子技术和计算机技术的高速发展使这种愿望变成了现实。从本世纪７０年代 For a long time, we have relied mainly on simulated seismograms to study the earth’s structure and determine seismic parameters. With the development of earthquake science, people need to have a better understanding of the earthquake source process and its mechanism, and require the provision of large dynamic, high-resolution and high-precision seismic data. The rapid development of electronic technology and computer technology has made this desire a reality. From the 70s of this century
