Using completely PVD method, successively depositing doffing pellicle twain anhydride and diamine on the polishing glass substrate in the high vacuum environment, and then processing heat treatment in proper surrounding temperature., make sure twain anhydride and diamine form polymeric amic acid, and more ring-imidization.

采用全物理气相沉积方法，在高真空环境中将脱膜剂、二酐和二胺先后沉积于抛光的玻璃衬底上，然后在适当的环境温度中进行热处理，使二酐和二胺形成聚胺酸，并进一步环亚胺化。

Chimney for high strength, thermostable Philippine your glass lens, condenses the effect well, the radiation distance is farther, is the aviation obstruction light first choice.

灯罩为高强度、耐高温的菲涅尔玻璃透镜，聚光效果更好，辐射距离更远，是航空障碍灯的首选。

The comparison of the derivative form of fixed aberration correction surface has been made with that of integral form surface as well as that of spherical surface in concentrating the solar ray.

同时，我们对以上两种不同表达式的曲面做了固定相差修正，并将这两种曲面，以及圆球面，分别做了聚光效果的模拟和比较。

Some conventional optical antennas like hemispherical lens, compound parabolic concentrator, Cassegrain telescope were analyzed with the software of ZEMAX.

针对非视线大气光通信的需求，利用ZEMAX软件对半球透镜、复合抛物面聚光器和卡塞格伦望远镜等光学天线进行了性能分析。

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。
