| 1. | A lens is an optical system including two refracting surfaces .
一个透镜是包含两个折射面的光学系统。 |
| 2. | Either a body absorbs light, or it reflects or refracts it, or does all these things .
一个物体不是吸收光就是反射或折射光，或是二者兼备。 |
| 3. | The optical system of a refracting telescope is essentially the same as that of a compound microscope .
折射望远镜的光学系统与复显微镜的光学系统基本上相同。 |
| 4. | The sun obscured by overcast, refracted from the jungle and heated the moist dark air .
云翳蔽空，日色朦胧，经丛林这么一反射，又阴又湿的空气就给烤得热烘烘的。 |
| 5. | That is, a plane refracting surface does not image all rays from a point object at the same image point .
就是说，平面折射面并不能将来自点物的所有光线都成象于同一家点。 |
| 6. | The light eddied and shifted as though refracting through the intricate vaults of a cathedral .
那淡淡的光线缥缈不定，袅袅似烟，象是透过大教堂结构奥妙的圆顶折射下来的一般。 |
| 7. | The light reflected and refracted several times by a droplet and then finally returned to the observer is therefore white .
光由粒子反射和折射数次，最后到达观察者，所以是白色的。 |
| 8. | It may be worthwhile to remark that the refracted and reflected waves are always excited in their totality if the following inequality holds .
但却值得指出，折射波和反射波总是全部被激发的，如果下列不等式成立的话。 |
| 9. | Black conducts , reflects refracts is it ? ,
黑色是传热的，或许反射要么就是折射吧？ |
| 10. | Light is refracted when passed through a prism
