平面度

The evaluation method and algorithm of shape error (roundness, plane straightness, space straightness, cylindricity) were discussed. A new kind of algorithm, namely mesh searching method, which can be used to evaluate the roundness error, plane straightness error, space straightness error and cylindricity error, were put forward. With this algorithm, the shape error can be obtained by transferring the distance formula repeatedly and simple judgment without linearzing the distance formula (from point to point or point to line) and choosing optimal direction and step length.

对形状误差(圆度、平面直线度、空间直线度、圆柱度)的评定方法及算法进行了讨论，提出了一种评价圆度误差、平面直线度误差、空间直线度误差及圆柱度误差的新算法——网格搜索法，该算法不需要对距离公式线性化，也不需要选定优化方向和优化步长，只需重复调用距离公式和简单的判断即可得到符合定义的形状误差。

The Go moved backward with 1.35mm and upward with 1.90mm in group I, the gonial angle increased for 3.69°, and angle between palatal plane and mandibular plane was increased for 5.00°; In group II, the Go moved backward with 1.85mm and upward with 3.32mm , the gonial angle increased for 4.06°, and angle between palatal plane and mandibular plane was increased for 5.22°. Both in group I and II, there was a tread for clockwise rotation of mandibular corpus. The length of pterygomasseteric sling was mild increased due to the backward movement of Go.

在Go点的变动方面，在Me点向前位移的族群里，术后Go点平均向后1.35mm，向上1.90mm， gonial angle 平均增大3.69度，腭平面与下颚平面的夹角则是增加5.00度；在Me点向后位移的族群里，术后Go点平均向后1.85mm，向上3.32mm， gonial angle 平均增大4.06度，腭平面与下颚平面的夹角则是增加5.22度，不论是向前或是向后的族群，结果皆显示翼咀嚼肌悬吊带有轻微被拉长的迹象。

In light of such problems as the long production period and the difficulty in controlling the planeness while polishing the surface of the coupler, a new design of the coupler is proposed. Meanwhile, the paper also discusses some methods to improve the polishing processes, i.e.

针对制作周期太长、控制研磨面平面度难等问题，提出了一种新的耦合器改进方案，并提出了一种可对打磨过程中包层剩余厚度进行实时监控的方法-液滴法。

The paper points out that the difference between the start point and each pitch is not independent,though each pitch is measured independently,and all of them are the function of measured value L.

本文指出测量平面度误差，尽管每个节点是独立测量的，但每个节点和开始点的高度差并不是独立的，且都是测量值L的函数。

Mosaic panels (such as turning the table, with KD in the table board, etc.), flatness error allowed in the soil between 0.4mm.

拼接面板（如翻板桌、附KD中板的餐桌等），平面度误差允许在土0.4mm之间。

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.
