The results of such modeling of multi-mode fiber approximately agree with the predictions of geometric optics, if the fiber core is large enough to support more than a f

结果，模拟多模光纤大约同意预测几何光学，如果纤维核心是大到足以支持多个模式。

The developing process about establish the model of earth surface and several classical methods, which are the methods of radiative transfer, geometric optics, hybrids of two or more of these, and numerical simulation are discussed in detail.

较详细地论述了建立地物散射模型的发展情况和几种典型方法：辐射传输方法、几何光学方法、复合模型方法以及数值模拟方法等，初步研究了适用于植被、土壤、沙漠等环境背景的双向反射分布函数模型。

Finally, we use Cooke Triplet and Double Gauss to be our design models. The negative index lens and traditional lens are compared in the geometric optics.

最后利用两组透镜组Cooke Triplet与Double Gauss 作为设计蓝图，把负折射率透镜与一般的传统透镜作为几何光学上的比较。

By treating photorefractive spatial soliton as rays in geometric optics, the action of the diffusion effect on propagation of PR spatial solitons is analyzed.

It gives the limitation of geometrical optics.

它给出了几何光学的限度。

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。
