高斯光学

By 1937 Zeiss listed about 20 high quality monocular, binocular and stereo microscope configurations in their literature. And they also marketed a wide selection of optional attachments and illuminators including at least 33 objectives of from 2X to 120X, and about 20 eyepieces of Huygens, Orthoscopic, and Compensating designs of from 3X to 30X.

1937年，蔡司文献上就已经有了大约20种高品质单目望远镜、双目望远镜和立体显微镜，并且还有很多可选的光学配件，说明书中列出了至少33种2倍到120倍物镜（其中包括6种为使用萤石型），至少大约20种3倍到30倍的惠更斯型，无畸变型(直线型Orthoscopic)，和补偿型目镜。

The flattened Gaussian beam is taken as an illustrative example, and the propagation of FGBs passing through unapertured and apertured paraxial ABCD optical systems is expressed in the analytical form.

以平顶高斯光束为例，推导出了它通过无光阑和有光阑的近轴ABCD光学系统传输的解析表达式。

By means of the Fourier series expansion, an approximate analytical propagation equation of flattened Gaussian beams passing through an apertured paraxial ABCD optical system is derived, and illustrated with numerical examples, when the transmissivity of the aperture is T = cos.

用傅立叶级数展开法研究了平顶高斯光束通过有光阑限制的近轴ABCD光学系统的传输特性，导出了光阑透射率为T=cos时的近似解析传输公式，硬边光阑的情况可作为Ω=0的特例得到。

The influence of the one-stage single-lens optical system on the divergence angle of Gaussian laser beam is analyzed theoretically.

在理论上分析了单级单透镜光学系统对激光高斯光束发散角的影响。

From the comparison,itcan be concluded that when passing through a same aberrated optical system,therelative intensity degradation for a Gaussian beam is less than that of an uniformbeam.

经过对比，可以得到这样一个重要的结论，即相对于均匀光束来说，同一像差光学系统对高斯光束的光强影响要小一些。

In chapter four,based on diffraction theory,we derived the far field intensitydistributions near geometric focus for off-axis Gaussian and uniform beams passing througha primary aberrated optical system.

在第四章中，基于衍射理论，推出了离轴高斯光束和均匀光束通过一个初级球差光学系统后，其几何焦点附近的远场光强分布公式。

This paper disuissed the deduction of the focal distance f using the Gauss method and the total yoke method in an imperfect situation,namely a situation where thin lens merely involve light core errors.

在普通物理光学实验中，在理想状态下测定薄透镜焦距常采用的方法有高斯法、共扼法、自准直法等。

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。
