查询词典 geometrical optics

It's in the assumption that the difference between geometrical and physical optics requires a "markedly different method of theoretical treatment."

问题在于宣称几何光学和物理光学之间的差异使得各自需要完全不同理论方法来处理。

Based on Fermat's theorem, the law of reflection and refraction is obtained, and the geometrical ray tracing method of reflected light is introduced. In response to geometric optics rainbow theory and Airy rainbow theory, the relationship formula of the N-order rainbow angle with the refraction index and the Airy peak value position formula are derived, and the physics causation of the first order rainbow are discussed and analyzed in detail. The distribution properties of the first and second order Airy structures of spherical particles are calculated.

利用费马原理推导了反射和折射定律，以反射射线的跟踪为例介绍了几何光学射线跟踪方法的推导过程；根据几何光学彩虹理论和Airy理论，推导了N阶几何光学彩虹角与入射角和折射率的关系及Airy峰的位置表达式，详细阐述了一阶彩虹形成的物理原因，计算了球形粒子的一、二阶Airy分布。

In this case, geometrical design methods are inadequate, but current physical optics methods are too slow.

在这种情况下，几何光学的设计方法已经无能为力，但是，现阶段的基于物理光学的计算速度太慢。

维持V沟尺寸的精度，需要足够的压力，但是若没有足够的熔胶作为压力传递的空间，则光学特徵之几何形状收缩变形，是造成导致导光板光学辉度下降的主因。

Based on the Lorentz-Mie theory, the single scattering characteristics of multi-dispersed spherical and multi-layered spherical particles are studied. The extinction coefficients, scattering coefficients, single albedos, single scattering phase functions and asymmetry factors of different clouds are presented. Numerical results for single scattering of spherical and non-spherical particles are obtained in the approximation of geometrical optics. The single scattering phase matrixes of non-spherical aerosols are calculated by using the T matrix method.

基于洛伦茨-米理论研究了服从一定尺寸分布的球形和多层球形粒子的单次散射特性，计算了各种不同类型云层的消光系数、散射系数、单次散射反照率、单次散射相函数以及不对称因子；利用几何光学方法计算了球形、非球形粒子的单次散射特性；利用T矩阵方法计算了非球形气溶胶的单次散射相矩阵。

In the case of little circular light source and rectangular slit, the simulation results of different myopic diopters are obtained by geometrical optical theory and Fourier optics respectively.

在假定照明光源是均匀分布的小圆形光源和狭缝为一矩形的条件下，分别利用几何光学和傅立叶光学给出不同屈光度下光强分布情况。

Based on geometrical and physics optics, the principle of light scattering method to measure surface roughness was analyzed. The mirror and diffraction model were set up which show there is a quantitatively corresponding relationship between light's intensity distribution of reflected flare—light scattered band and surface roughness parameters.

作者通过对光学非接触表面粗糙度、微位移测量单元技术进行分析，确定以结构简单、测量速度快的光散射法测量表面粗糙度；以光散射法测量表面粗糙度和光学三角法测量微位移这两种不同工作原理和功能的光电传感器作为集成对象，使二者实现相同光源、相同光路、相同光敏接收器的光电传感器集成。

Based on the geometrical optics, the thesis first analyzes the basic principles of out-of-focus, summarizes the basic flow of automatic focusing, points out that focusing evaluation function and focusing control strategy are two basic technologies in automatic focusing of image method. The thesis lists most of focusing evaluation functions and explains how to implement different control strategies.

本文首先用几何光学理论分析了离焦产生的基本原理，深入研究了图像法自动调焦的关键技术，指出调焦评价函数和调焦控制策略的选取是图像法自动调焦的两项核心技术，并按类别介绍了已有的各种调焦评价函数、控制策略实现方法。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
