Because P and S waves travel at different but fairly constant speeds, the interval between their arrivals increases in proportion to the distance from the earthquake focus, or initial rupture point.
由于P波和S 波以不同但相当恒定的速度传播，它们到达的间隔与到震源或初始破裂点的距离成比例地增加。
P-waves are sometimes known as primary waves, because they travel faster through the Earth and so are the first to arrive at monitoring stations.
P波有时被看作纵波，因为它们以更快的传递速度穿越地球内部，因此最先被地震监测站台发现。
For P&G’s management, the biggest appeal may be the cost savings, which rumours suggest may be 15-25% of its previous travel budget.
对于保洁管理层来说，该系统最大的优点应该是节省成本，据说只有从前差旅预算的15%到25%。
Secondary waves travel more slowly and arrive after the P-waves.
次要波传播的更慢，发生在P波之后。
In addition to 9,000 researchers in 11 research centres around the world, P&G has 75 technology scouts who travel the globe in search of new ideas that P&G might take up and develop.
除了遍布全球的11座研究中心的9000名研究人员之外，宝洁还有75名技术探子，他们巡游全球，搜寻宝洁可以借鉴使用的新点子。

For the P-SV wave travel time, it also can be expressed exactly by a three-term Taylor series in short or moderate spreads.
SV波的传播时间也可用三项泰勒展式表达，在中等及短排列长度时可达到一定精度。
All candidates must have good communication skill, competent P. C. skill; can work under pressure and willing to travel extensively or based on Project site.
所有应聘人员均要求具备良好的沟通能力、熟悉使用电脑，能够承担一定的工作压力并愿意时常出差或常驻在工地现场。

除了遍布全球的11座研究中心的9000名研緟跛员之外，宝洁还有75名技术探子，他们巡游全球，搜寻宝洁可以借鉴使佣的新点子。
Using the data of natural earthquakes, we have studied the characteristics of P-wave travel time in Qinghai-Xizang plateau and its vicinity.
本文利用天然地震资料，研究了青藏高原及其邻区的P波走时特征。
The three term Taylor series of P-P wave or P-SV wave reflection travel times in VTI media are the function of elastic parameters. Therefore they can be used to inverse the seismic elastic parameters.
对P P波、PSV波的传播时间进行三项泰勒展开时，它们的系数中包含了地震波的各向异性信息及垂直速度信息，可以为地震波的弹性参数反演提供基础。
And researchers found that P waves travel through both liquids and solids while s waves travel only through solid matter.
研究者发现P波可以同时穿过液体和固体，但是S波只能穿透固体。
And research found that P waves travel through both liquids and solids, while s waves only travel solid matter.
研究发现P波可以同时穿过液体和固体，而S波只穿过固体物质。
And research found that P waves travel through both liquids and solids, while s waves only travel solid matter.
研究发现P波可以同时穿过液体和固体，而S波只穿过固体物质。
