一、引言地震图是地震台所记录到的震源和地球内部构造大量信息的图纸,是地震学和地球物理学研究的重要资料来源。有了它可以做许多工作。如研究全球性的地震活动性,大地震的破裂过程,断层面的力学结构……等等。因此,如何珍惜和保护地震图,高效率的利用它,实现对这些资料的现代化管理,已经是很迫切的任务了。就目前来看,采用缩微技术是解决以上 I. INTRODUCTION Seismograms are drawings of seismic sources recorded by seismographs and massive amounts of information inside the Earth. They are important sources for seismology and geophysics research. With it you can do a lot of work. Such as the study of global seismicity, the rupture of large earthquakes, the mechanics of fault planes ... and so on. Therefore, how to cherish and protect the seismogram, make efficient use of it, and realize the modern management of these materials has become an urgent task. For now, the use of micro-technology is to solve the above
