The ECM productivity of inner ratchet wheel is very high. Cathode piece is machined easily using WEDM. Its dimension is nicety. Cathode is not worn down in process,so a piece of cathode can be repeat used to machining tens or several hundred parts. The surface quality of inner ratchet wheel being machined is nice. There is no burr in the surface. Its surface roughness can reach Ra1.6μm.Its ...

应用电化学加工技术加工内棘轮，生产率很高；采用线切割加工片状工具阴极，制作方便、尺寸准确；加工过程中工具阴极无损耗，一片阴极可以重复加工几十至几百个零件；加工出的内棘轮表面质量好，无飞边毛刺，表面粗糙度可达Ra1.6 μm ；加工精度较高。

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。
