The direction vector of benchmark at the beginning position is nz1＝nt1,when the middle gasbag follows along straight line, the coordinate of the centre of a circle is where d03 is distance of the centre of a circle between the middle gasbag benchmark section and drill mud head benchmark section.

The基准方向向量首先安置 is nz1＝nt1，当中间气囊沿平直的跟随line，圈子的中心的座标是 where d03是一个圈子的中心的距离在之间的 middle气囊基准部分和钻子泥朝向 benchmark部分。

Using these traced regions, we can calculate the centroid, and the size, and the average motion vector of the moving objects.

使用这些追踪后的区域，我们可以计算出物体的质心、大小、和平均运动向量。

Based on Bezier curve continuance of first－order and second－order derivative, the characteristic vector equation of two Bezier curve is presented in point of intersection. The algorithm is not only of high accuracy with all of the interpolated points being on the curve theoretically, but also of very high speed in the real－time interpolation processes. The interpolation velocity does not change and the segment tolerance of interpolation can be control by selecting the parameter in cerement rationally every time.

为保证两段Bezier曲线在连接点处一阶导数、二阶导数连续，导出了两段Bezier曲线特征向量应满足的关系方程，Bezier插补法不仅在理论上可使所有的插补点落在曲线上，而且实时插曲补速度高，每次插补时可合理地选择参数增量，能使插补速度保证不变，也可控制弓高误差。

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.
