The truing feature of vitrified and resinoid bonded CBN wheels trued by RDD with up-truing and down-truing and the property of grinding workpiece with CBN wheels is obtained.

4，研究金刚石滚轮在不同的修形速比下，对陶瓷、树脂结合剂CBN砂轮进行逆向和顺向修形的特性及其修整后CBN砂轮对高速钢工件的磨削特性。

The machine revolves so often each minute; so many movements have to be made, so many pieces produced each hour. Resuit.

机器每分钟运转多少次，就必须有多少个动作要完成，每小时就必须生产多少工件。

Both workpiece rotation and target rotation adopt a modular riving circuit of dynamos that produces a direct current. Armature stepping down and starting can be achieved by PLC the software procedure.

工件旋转和靶旋转均采用模块化的直流电机驱动电路，通过PLC软件程序实现电枢降压软起动。

Sometimes, however, certain portions of a piece may require more than one roughing cut.

不过，有时工件的某些部位可能需要不止一次的粗切削。

Are machined to the required shape and size with only one roughing and one finishing cut.

按JB/T7977-99标准制造，材料HT250，工人面采用刮研工艺，是用来测量工件的直线度和平面度的量具，使用温度（20±5℃）。

The key to soldering is simple: Heat the work, not the solder.

焊接的关键因素是简单的：加热工件，而不是焊料。

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。
