P wave - Wikipedia
A P wave (primary wave or pressure wave) is one of the two main types of elastic body waves, called seismic waves in seismology. P waves travel faster than other seismic waves and hence are the first signal from an earthquake to arrive at any affected location or at a seismograph. P waves may be transmitted through … 展开
The name P wave can stand for either pressure wave (as it is formed from alternating compressions and rarefactions) or primary wave (as it … 展开
Primary and secondary waves are body waves that travel within the Earth. The motion and behavior of both P and S waves in the Earth are monitored to probe the interior structure of the Earth. Discontinuities in velocity as a function of depth are indicative of … 展开
Velocity
In isotropic and homogeneous solids, a P wave travels in a straight line longitudinally; thus, the particles in the solid vibrate along the axis of propagation (the direction of motion) of the wave energy. The velocity of P waves in that … 展开CC-BY-SA 许可证中的维基百科文本 P Wave, The Difference Between P And S Waves And P …

P波（地震波形）_百度百科
- 震源处的岩层活动产生强烈震动时，会产生一种以很快速度向四面八方传播的波，其中一部分传到地球表面，这就是地震波。地震波分为纵波和横波。振动方向与波前进的方向相垂直的是横波，与传播方向相一致为纵波。纵波每秒种传播速度5~6千米，能引起地面上下跳动；横波传播速度较慢，每秒3~4千米，能引起地面水平晃动。

Seismic Waves - P Waves - Cyberphysics
P Waves are a type of seismic wave called a body wave - they are called this because they travel through the body of the Earth. See surface waves. A P wave travels the 'fastest' of all of the waves we monitor. It therefore arrives first at …
