光电信息工程专业英语 Chapter 1 Geometrical Optics Glossary Photosynthesis　 光合作用 Apparent 　明显的，清晰的 Magnitude　 数量，辐度 Violet 　紫光 Ultraviolet 　紫外 Infrared 　红外 Undergo 　经历，遭受 Incident 　入射的 Intensionally　故意地 Polish　抛光 Flexible 　柔韧的 Parabolic 　抛物的 Cylindrical　柱体的 Spherical　球面 Moderate 中等的，适度的 Positive 正的 Negative　负的 Symmetry 对称的 Essentially 本质的，本来的 Curvature 弯曲　曲率 Conversely 相反 Identical　相同的，一样的 Deviated　偏离，脱轨 Laterally　横向的 1.1 Models of Light: Rays and Waves 1. The idea that light is composed of a stream of particles is also consistent with the observation that a beam of light from a flashlight or a laser seems to travel in straght lines except when it encounters an interface between two optical media. 句子结构： The idea…..is consistent with….observation. 定语从句： The idea that light is composed of a stream of particles… the observation that a beam of light from a flashlight or a laser seems to travel in straght lines except when it encounters an interface between two optical media . 名词复数：media 光是由粒子流构成的这种想法与观察（闪光灯或激光的光束看起来好象沿直线行进，除非遇到了两个光学媒介的界面）是一致的。 The idea that light is composed of a stream of particles is also consistent with the observation that a beam of light from a flashlight or a laser seems to travel in straight lines except when it encounters an interface between two optical media. 光是由粒子流构成的这种想法和观察是一致的，我们观察到除非遇到了两个光学媒介的界面，通常情况下闪光灯或激光的光束看起来是沿直线前进的。 1.1 Models of Light: Rays and Waves 包含可见光的波长范围仅仅是整个电磁谱中的一小部分，它跨越了许多种顺序，没有严格的分界线区分不同的区域，从一个区域到下一个只有一个连续的混合。 2. The range of wavelengths that comprise visible light makes up only a small portion of the entire electromagnetic spectrum, which spans many orders of magnitude. There are no sharp dividing lines separating the various regions; there is just a continuous blending from one region to the next. 1.1 Models of Light: Rays and Waves 3. The behavior of all electomagnetic waves can be predicted from Maxwell’s equations and a knowledge of the composition and shape of the lenses, reflectors and other components involved. Microwa
