| 1. | A marine detector is a hydrophone . 海洋检波器是水中地震检波器。 |
| 2. | The seismometers are usually termed geophones . 地震计一般称为地震检波器。 |
| 3. | This leads us to the concept of arrays of detectors . 这就导致检波器组合的概念。 |
| 4. | The wires and detectors are liable to induction from the power lines . 导线和检波器易受高压线感应。 |
| 5. | We can implant many detectors over an area which is large enough . 我们能在足够大的范围内安置许多检波器。 |
| 6. | It is scarcely practical to consider deep burial of the detectors on land . 几乎不能考虑在陆地上深埋检波器。 |
| 7. | This technique imposes no chance on the main seismic instruments or detectors . 这种技术并不要求改变地震仪或检波器。 |
| 8. | A detector at b will then record the time of arrival of the reflected wave . 于是在B点的检波器将记出反射波到达的时刻。 |
| 9. | The output of the detector is the video-signal proper, with a 2-volt swing . 检波器的输出是相应的视频信号、摆幅为2伏。 |
| 10. | We can imagine a seismic detector being bombarded by myriads of grains of sand . 我们可以想像检波器受几万个砂粒冲击的情景。 |
