查询词典 turning point

Compared to the germanium, a common material used in infrared field, chalcogenide glasses possess the characteristics of low-cost and the little value of dn/dt. Besides, it is amorphous glass, which is produced the spherical and aspheric lens by using a molding process instead of single-point-diamond turning. Thus the mass manufacture cost of infrared lens will drop obviously, the stability and consistency of product is guaranteed.

相对于红外领域常用的材料单晶锗，硫系玻璃不但具有低成本，折射率随温度变化小的特点，而且，由于它是非晶态材料，可以用精密的模压工艺来代替用于晶体材料的单点金刚石车削工艺，其批量加工的成本得到了大幅的降低，产品的稳定性，一致性也得到了明显的提高。

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。
