In this system, the gratings are inscribed by the UV interference fringes of 248 nm derived from a rotatable biprism, where the phase mask is used as a beam splitter, and the biprism is rotated to change the intersection angle of two beams.

在该系统中，光纤光栅是由来自可旋转双棱镜所形成的波长为248 nm的紫外干涉条纹写入的，其中，相位掩模被用作1级衍射光的分束器，通过双棱镜的旋转可改变两写入光束的交叉角。

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.
