| 1. | This earthquake affected several cities in the vicinity . 这次地震波及周围几个城市。 |
| 2. | Seismic sections show the response of the earth to seismic waves . 地震剖面是地壳对地震波的响应。 |
| 3. | He discussed the propagation of waves through the earth's interior . 他探讨了地震波在地球内部的传播。 |
| 4. | It is a straightforward task to calculate the radiation of different waves . 计算不同地震波的幅射并不困难。 |
| 5. | Seismic velocity can occasionally be affected by porosity and temperature . 孔隙率和温度有时也能影响地震波速。 |
| 6. | Let us now face the problem of the actual mechanical generation of the seismic waves . 现在让我们来看看地震波的实际发生机制问题。 |
| 7. | Attenuation of seismic waves between such surfaces can be similarly diagnostic . 在这些界面之间地震波的衰减,同样可以作为一种标志。 |
| 8. | 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。 |
| 9. | Small charges damp the shock wave faster and do not affect the whole building in the same way . 装药量小则地震波较快地得到减弱,并且照样不影响整个建筑物。 |
| 10. | The source of earthquake waves-the site beneath the surface where the disturbance originates-is known as the focus . 地震波源--地表底下产生扰动的地方--称为震源。 |
