And then, a window-type novel x-ray crystal spectrometer was put forward based on the elliptically curved crystal analyzer. It was coupled to an x-ray CCD camera, and a set of system had been designed and constructed. The spectrograph is useful in the experiments of x-ray diagnostics, for example in x-ray lasers, inertial confinement fusion, laser-matter interaction, and so on.

本论文从X射线晶体衍射和椭圆自聚焦几何光学原理出发，剖析追究了椭圆型弯曲X射线晶体谱仪在实际应用中产生问题的根源，率先从技术上提出解决目前椭圆型弯曲X射线晶体谱仪存在问题的思路，论证了其相应实施方案的可行性。

The "emmetropia" in geometrical optics and "the normal eye of refraction" in biomedicine were two different concepts, and should be differentiated.

几何光学的"正视眼"与生物医学角度的屈光"正常眼"是两个不同概念，应予以区分

With a CCD camera and a frame grabber to capture the laser spot, the digital image is transferred to special software for further processing, the amount of the laser spot drift can be achieved. The amount of the drift in X direction, Y direction and in spatial angle can be obtained through geometrical optics.

它采用CCD摄像头和图像采集卡采集激光器输出光斑，通过专门软件对数字图像进行处理，得出光斑漂移的大小；另外，利用几何光学方法得到了激光光束在X方向、Y方向以及空间立体角上的漂移大小。

The lighting calculation of light guide is a complex problem, which is always based upon the geometric optics.

导光管照明计算是一个十分复杂的问题，国内外已有的导光管照明计算多建立在几何光学的基础上。

Under the assumptions of geometric optics and thin phase screen the retrieval algorithms of amplitude in GPS/LEO occultation technique were listed in this paper, respectively.

本文在几何光学和薄相位屏的假设下，分别介绍GPS/LEO无线电掩星反演地球大气技术中振幅反演的计算方法。

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。
