而对一些小震群的研究得到震群地震尾波率衰减变化不大的初浅印象。
Study of a number of small seismic swarms also gives us the preliminary understanding that the attenuation rate of seismic coda waves of swarms does not change considerably.
根据初至波特点,基于数字图像处理技术,提出了应用边缘检测和边缘追踪技术进行初至波自动拾取的方法。该方法的实现过程为:①对地震记录做单道归一化处理;
The digital image processing such as edge detection and boundary tracing to pick up the first break time is discussed in this paper, which based on the specialty of first break time.
