这是第一个不同点在普通光束和镭射光束之间。
That's the first difference between a beam of ordinary light and a laser beam.
因此，与普通光束比较，激光束的确是十分整齐的。
So compared with any ordinary beam of light, the laser beam is very orderly affair indeed.
第三个不同点是：普通光束分离；而镭射光束却不然。
The third difference is this: a beam of ordinary light diverges; a laser beam does not.
而普通光束就像人群涌向足球赛场，相互推挤、碰撞。
In an ordinary beam, the waves are like the people crowd going to football match, pushing and bumping into one another.
好了，那些是三个不同点在普通光束和镭射光束二者之间。
Well, those are the three differences between a beam of ordinary light and a laser beam.
在普通光束中，光波就像成群的人去观看足球比赛一样，互相拥挤和碰撞。
In an ordinary beam, the waves are like the pople in a crowd going to a football match, jostling and bumping into one another.
虽然粘着剂在普通光照下看不见，但一旦变硬便可以在紫外线光束的照射下变成黄色。
Though invisible in normal light once it has hardened, this adhesive glows yellow when illuminated by a beam of ultraviolet of the sort often used in discotheques.
