LTHJ-SUPER-A1 Gantry welding automatic recovery machine This system is set for one body super new portal welder, special cylindrical welding tools or difficult welding. It adds super negative pressure wind pump on inner side of flux cylinder, so that in the welding process it can absorb unlyzed flux directly into cylinder and place into a small hopper. Open the valve of small hopper and put flux onto work piece, then you can put it into repeated usage.

LTHJ-SUPER-A1型龙门焊自动回收系统本系统是一体超强新型的门式焊机或外圆焊接特制工具、高难度的焊接而设置的，它就是一个焊剂筒内加上超强负压风泵，使在焊接过程中尚未溶化的焊剂直接吸收到筒内，放置到小料斗中，打开小料斗阀门把焊剂放到工件上，进行往复使用。

Tommy: This is a file and that is a workpiece .

这是把锉刀，那是工件。

How to improve the precision of online measurement of large size workpiece is an important task for large machining.

如何提高大尺寸工件的在线测量精度，是大型机械加工的重要课题。

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。
