| 1. | Motors for 220 v are connected to the ordinary lighting grid .
220伏电机接到普通的照明线上。 |
| 2. | Accordingly, laser light is said to be much more coherent than ordinary light .
所以，我们说激光的相干性比普通光强得多。 |
| 3. | The degree of contrast will also be diminished by the presence of some vagrant ordinary light .
反差度还将因某些杂散自然光的存在而降低。 |
| 4. | Because of their short wavelength, x-rays can pass through objects which are opaque to ordinary light .
由于X射线的波长短，它就能穿透一般光线所不能穿透的物体。 |
| 5. | This is the second : a beam of ordinary light is continuous
第二个区别是：普通光束是连续的。 |
| 6. | Use compact fluorescent light bulbs instead of ordinary light bulbs
使用悭电灯泡代替普通的白热灯泡。 |
| 7. | That ' s the first difference between a beam of ordinary light and a laser beam
这是第一个不同点在普通光束和镭射光束之间。 |
| 8. | The third difference is this : a beam of ordinary light diverges ; a laser beam does not
第三个不同点是：普通光束分离;而镭射光束却不然。 |
| 9. | Well , those are the three differences between a beam of ordinary light and a laser beam
好了，那些是三个不同点在普通光束和镭射光束二者之间。 |
| 10. | A beam of ordinary light gets wider and wider , and therefore weaker and weaker , as it goes on
普通光束会变得越来越宽，也因此愈来愈弱，在光束行进中。 |
