Calculation of teeth profile of disc cutter for arc-gear;2. The formulas for setting angle and entrance angle of disc cutter s are derived by using the contact condition of space curve.

利用空间曲线相切条件导出了用于计算盘形刀具安装角和切入角的条件；该方法具有以下优点：无需知道工件齿形，可同时获得刀具宽度、半径等参数。

The theory of current straightness measurement of 2 points equidistance is studied deeply in this paper, based on which, a new method of on line measuring of generatrix straightness for the cylindrical workpiece is presented.

本文对现行的双测头等截距测量直线度理论进行了深入的研究。在此基础上，提出了一种圆柱形工件素线直线度误差在线测量的新方法。

Design of irregular template based on the concentric equipotential line of target contour,combined with the projection,can quicly and efficiently realize automatic identification and position of irregular images by the computer.

针对工业自动装配产品过程中异形工件出现旋转后的定位问题，提出一种新的异形目标识别方法，设计基于目标轮廓的同心等势线异形模板，并结合圆投影方法，能快速有效地实现计算机对异形目标的自动识别与定位。

According to spectral characteristics of the HCVAW arc in a body, energy factor which value equals to the ratio of two spectral lines' intensity, was defined.When τ's value was less than 0.1, the HCVAW arc was exhibitive of diffusedshape with lower energy density instinct; and when τ's value was higher than 0.5,the arc was a fine-constricted arc with higher energy density.

从积聚态电弧的谱线空间分布来看，阳极材料为水冷铜板时，自空心阴极端面到阳极工件，氩原子谱线相对辐射强度具有比氩一次离子谱线相对辐射强度更快的减弱趋势，最大辐射强度均出现在距空心阴极端面2mm左右的位置。

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.
