初至波 meaning in English
first-motion wave
primary wave
Examples
- The analysis of seismograms indicates that the first arrival is a p-wave, followed by a s-wave .
地震波记录曲线的分析表明，初至波是P波，随后是S波。 - The analysis of seismograms indicates that the first arrival is a p - wave , followed by a s - wave
地震波记录曲线的分析表明，初至波是p波，随后是s波。 - Considering the specialty of first break , this paper discussed edge detection and spline interpolation used for first break picking
摘要初至波自动拾取方法已有很多，但在实际应用中或多或少都受到一定的限制。 - In order to eliminate its disadvantage of slowness , the basic algorithm for first - break waves was improved to speed its calculation without decreasing its accuracy so that it can be put into practical use
针对这一问题，对其初至波基本算法进行了改进，在保证精度的条件下，改进算法的计算速度显著提高，达到实用要求。 - Firstly , we determined the position of energy edge in every trace by using edge detection algorithm , secondly , we divided all the edge points into wrong points and correct points , then calculated the value of wrong points by spline interpolation
为此，从初至波的特点出发，提出了单道数据边界检测和样条插值相结合进行初至波自动拾取的方法。
