This machine is used for the milling process of the H-barand box beam, the ma-ximum piece end which can mill is 1500×1500mm, and takes the advantage of con-venience, simplicity, rapid-adjusting.

本机用于焊接或轧制成型的H型钢及箱形梁两端面铣削加工，能铣削的最大工件端为1500×1500mm，具有操作方便、结构简单、调整迅速等优点。

With the geometry model of the ball end mill, the method of theoretic cutting force analysis combined with the identification of the experimental coefficients of milling forces is used to develop the milling force model of a helical ball end mill.

给出了球头铣刀刃线几何模型，采用理论切削力分析与实验-系数识别相结合的方法，建立了新的螺旋刃球头铣刀的铣削力模型；建立了考虑刀杆柔性的球头铣刀铣削振动模型；考虑刀具动态变形和工件表面波纹对切削厚度的再生反馈，建立了球头刀铣削动力学模型，对动态铣削过程进行了仿真，证明离线仿真可以对铣削过程动特性做出准确的预测。

It is this boundary-work that makes the typology useful for avoiding extreme technological determinism, social constructivism, and noetic flatness in conceptualizing an artifact's political qualities, and for thinking about how these qualities change through time.

正是这种边界的工作，使避免极端的技术决定论，社会建构主义类型学有用的，在构思一个工件的政治素质智力平坦度，以及思考如何通过时间改变了这些特质。

The biggest characteristic of this model is that the hydraulic system pump station, operating console and working clamp installation table can be installed and connected in users sites and dived the test workpiece into the pond, can lift up and down, left and right two directions clamp worktables set 90 degree overturn function, especially suitable for gas pressure test.

本机型最大特点由液压系统泵站，操作控制台和工作夹紧装置台在用户现场安装连接，将试验工件潜入水池中目测，可上下升降，左右两向夹紧工作台设有90度翻转功能，特别适应气体压力试验。◎适用于直通法兰式阀门的密封压力和阀体强度压力性能试验。

Finally, high quality workpieces is obtained by the above two methods.

并且通过两种方法都实现了对工件的高质量磨削。

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。
