与以前发表过的相关理论、数值和实验结果作了较为深入的比较。

A circular arc of90=;one fourth of the circumference of a circle.

这些人患病的危险性不到他们的四分之一

Furthermore,some circular arc spline curves which have C~0 or GC~1 continuity are constructed.

This paper also describes the conditions for ensuring two engagement lines with double concave-convex circular arc profile.

讨论了中心距偏差和切深偏差相互补偿问题。文中还讨论了双圆弧齿形保持双啮合线的条件。

An interpolation algorithm of circular arc in an arbitrary plane was provided, and its feasibility was verified using language C.

本文还提出了一种可插补空间任意圆弧的插补算法，并用C语言进行了可行性验证。

The resulting arc spline is shape|preserving, and has the same number of inflections with the original polyline;(2) The segment number of circular arcs is the same as that of data points.

这种算法具有以下 3个特点：(1)生成的圆弧样条曲线具有保形的特点；(2 )圆弧样条中圆弧的段数与型值点个数相同；(3)圆弧段之间的连接点不一定在插值的型值点上，这样就能用更多的自由度来控制拟合曲线的形状。

Since cross ratio is an invariant of the group of all Mbius transformations,and a Mbius transformation maps a circle into another circle, it is convenient to represent a segment of circular arc with a parametric complex rational function.

利用Mbius变换的保交比性质和保圆性质，给出了一种快速、简便地生成平面上的一段精确圆弧曲线的新方法。

Secondly, the method of comminute piece of circularity arc and potential slip side cast are improved on.

其次，对圆弧的条分法和潜在滑动面搜索方法作了改进。

They have generous lateral misalignment allowances and can actuate through an arc without a clevis mount.

它们侧向排列对齐的允许公差很大，只需弧形而无需U形夹即可启动。

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。
