Improving offshore reflection techniques in consideration of all aspects of a primary seismic wave;
从地震纵波的全貌看海上反射法地震技术的改革
Conventional land vertical seismic profiling (VSP) exploration usually uses P-wave sources and three-component geophones for receivers, emphasizing P- and converted S-waves.
常规陆上VSP(Vertical Seismic Profiling)勘探普遍采用纵波震源激发,三分量检波器接收,主要利用的是纵波和转换横波信息。
This paper points out that the high-density electric method and shallow seismic reflection method have a better effect on the exploration of mining cavities.
本文通过大宝山矿已知采空区和勘查区的几种物探方法的测量结果,提出了高密度电法和浅层地震纵波反射法对采空区的勘查具有较好的勘探效果。

P waves move faster than S waves.
纵波波速大于横波。
Normally the shear velocity is about half of the compressional velocity.
一般地说横波速度大约是纵波速度的一半。
Seismic surveying is largely concerned with the primary P waves.
地震勘探主要研究一次纵波。

The second marks the arrival of transverse vibrations which travel more slowly,
然后记录下的是横向波的到达，横向波比纵向波传播得慢，
However, the earliest long-period seismographs recorded dispersive waves with large transverse displacement components in the main tremor.
但是，最早期的地震记录，就记录下了主震中具有很大横向位移分量的频散波。
