查询词典 waves

These counteracting forces of gravity and pressure create oscillations, analogous to sound waves created in air by pressure differences.

Figure 41-7 shows two plates of glass separated by a wedge of air; we want to consider interference between the two light waves reflected from the surfaces adjacent to the air wedge, as shown.

If the observer is at a great distance compared to the other dimensions of the experiment and the rays are nearly perpendicular to the reflecting surfaces, then the path difference between the two waves (corresponding to r1-r2 in the preceding section) is just twice the thickness d of the air wedge at each point.

如果观察者比起实验装置来讲距离较远而且光线较接近于垂直反射于表面，那么这两光波的光程差(在前面所述的相应部分 r1-r2)就仅仅是空气劈尖在该点处的厚度 d 的两倍。

The result shows that large airgun source excited in reservoir environment is rich in low frequencies (0 Hz), and is effective to produce waves with long-offset and deep crustal penetration.

试验结果表明，大容量气枪震源是具有丰富的10Hz以下低频信号的低频震源，其激发的地震波具有传播距离远，穿透深度深的特点。

The term "airwave" comes from the fact that human speech, in its native form, is an acoustic means of communications which makes use of the physical matter in the air to conduct compression waves.

术语"airwave"来自人的话音，其本来的形式是一种声学通信方法，利用空气中的物理介质传输压缩波。
