| 81. | The diameter of a 100-nanometer-wide wire would span about 500 atoms of silicon. |
| 直径100奈米的导线所跨越的矽原子就有500个之多。 |
|
|
| | |
| 82. | If the coil were wound using a conventional wire such as copper, magnetic energy would be dissipated |
| 若线圈是用如铜这样传统的导线绕制的话,由于导线对电流的电阻,磁拨就会因导线发热而损耗。 |
|
|
| | |
| 83. | When an electric current flows through the wire, these electrons also drift slowly along the wire, passing |
| 当电流通过电线时，这些的电子也沿着导线缓缓地从一个原子流过另一个原子。 |
|
|
| | |
| 84. | A third example is the electrical resistance of a wire, which also varies with hotness and coldness. |
| 第三个例子是导线的电阻，它也随冷热的变化而变化。 |
|
|
| | |
| 85. | It's also easy to turn into wire. |
| 它很便宜，几乎是现成的，而且还很容易被加工成导线。 |
|
|
| | |
| 86. | Electric current rising from the ground into the leader quickly vaporizes the wire. |
| 而自地面窜升进入导闪的电流，会快速将导线汽化。 |

| | |
| 88. | In 1837 he was granted a patent on an electromagnetic telegraph that transmitted signals along a wire |
| 1837年他实现了通过一根导线传输电磁电报,并获得了专利。 |
|
|
| | |
| 89. | The diameter and the length of the wire are not the only factors to influence its resistance. |
| 导线的直径和长度不是影响电阻的仅有的因素。 |
|
