在使用电子计算机对地震资料进行预处理时需要进行各类校正和走时折合工作,这些繁琐的工作极大地影响了预处理工作的效率和质量,本文提出了用硬件化措施实现上述工作的方案,阐述了原理方法,介绍了关键电路的设计,实际使用结果等。为了准确无误的用硬件化实现上述工作,对上机必需的零时信号进行了较为完善可靠的处理,达到了较高的时间精度。本文对该部分电路的构思、设计、参数选定等做了详细介绍。 The preprocessing of seismic data using electronic computers requires various corrections and travel time conversions. These cumbersome tasks greatly affect the efficiency and quality of the preprocessing work. In this paper, we propose a scheme of using hardware to implement the above work, Described the principle and methods, introduced the design of key circuits, the actual use of results. In order to realize the above work accurately and with hardware, the zero-hour signal necessary for the on-board machine has been processed more perfectly and reliably, reaching a higher time precision. This part of the circuit concept, design, parameter selection made a detailed introduction.
