| 1. | A sketch of his apparatus is shown in figure 3-2 .
图3-2是他的实验仪器的简图。 |
| 2. | The imperfections of the instrument increase this value .
仪器的缺点又加大了这个数值。 |
| 3. | The magnetic cores of transformers and other apparatus are laminated .
把变压器及其它仪器的磁心分层。 |
| 4. | When a shock came it shook the rigid table upon which devices placed .
当震动到达时，就震动了这张上面放着仪器的坚硬桌子。 |
| 5. | The performance of these instruments is quite different from that of those used to date .
这些仪器的性能和迄今所使用的完全不同。 |
| 6. | The apparatus thus described , however , records only the horizontal component of the wave movement .
然而，仪器的如此描画只能记录波运动中的水平方面的部分。 |
| 7. | A strong earthquake near the instrument will usually displace the reading off scale or may even damage the instrument .
如果在这类仪器的附近发生一次强烈的地震，一般就会使记录出格，甚至可能损坏仪器。 |
| 8. | The division into four frequency ranges was made to correspond with typical frequency limits on four different types of recording instruments .
分成4个频率范围是为了与4种不同类型记录仪器的典型频率限度相适应。 |
| 9. | The engineer requires a rugged device that will accurately record the heaviest shocks in the near vicinity of the instrument .
工程师所需要的仪器应该有结实的装置，即使在仪器的附近发生最强烈的振动时，也能够把它精确地记录下来。 |
| 10. | The apparatus thus described , however , records only the horizontal component of the wave movement , which is , in fact , much more complicated .
然而，仪器的如此描画只能记录波运动中的水平方面的运动部分，而波运动实际情况复杂得多。 |
