| 1. | The light beam passes through the container holding the vapor . 光束通过盛蒸汽的容器。 |
| 2. | The light beam is scattered by small particles in the moving fluid . 光束被流动流体中的微粒所散射。 |
| 3. | Each quantum of light is removed from the light beams by absorption . 每一个量子由于吸收作用而从光束中消失。 |
| 4. | The light beam can be steered more accurately than a mechanical cutter . 这种光束比机械切削器能运转得更为精确。 |
| 5. | This device splits the light beam into a measuring light beam and a reference light beam . 此设计把光束分成测量光束和参化光束。 |
| 6. | Under astigmatism even narrow parallel light beams will not combine into one point . 有象散存在时甚至很窄的平行光束都不能会聚在一点。 |
| 7. | The light beam from a laser will not spread out as the beam from a flash light or searching light does . 从激光中发出的光束不象手电筒或探照灯发出的光束那样扩散开。 |
| 8. | Smoke detectors - line detectors using an optical light beam 线型光束感烟火灾探测器 |
