And it is noted that the velocity field in a hydrocyclone is divided to two areas, i.e. the outer para-free-vortex and the inner para-forced vortex. The boundary surface of the velocity field is the maximum tangent velocity track surface, which is a cylinder when the hydrocyclones structure is reasonable.

分析研究结果表明，旋流器的切向速度场由外部准自由涡和内部准强制涡两个区域构成，其分界面为最大切向速度vtmax的轨迹面，结构设计合理时，此轨迹面为一圆柱面。

Liquid layer surface tension draw tight the liquid surface along the tangent

液层表面张力沿曲面的切线分向拉紧液面，形成向心回缩力，是吸气的阻力。

A gear H62 which made in yellow brass with the same mode number m=0.34, 2mm thick and had a center hole, when the gap get C=0.5%t , and punched with compound punching die, and the dimension accuracy reached IT7, the part have a flat surface ,the verticality of tangent plane reached 89.5°, its roughness Ra magnitude are 12.5μm, height of burr are 0.10mm; and the punching part are punched with progressive die, the gap C=7%t , initial accuracy are IT11, and have an more rough surface, even can see the gap with eyes.

例如料厚t=1.5mm的H62黄铜冲裁件，选用C≤40%t单边Ⅰ类小间隙冲裁比选用C≤8%tⅢ类大间隙冲裁，冲件固定误差将加大40%～60%，精度至少降一级。此外，采有无搭边排样，冲件的误差要远大于有搭边排样冲件。无搭边排样冲件。无搭边排样冲件的精度低于IT12级，而多数有搭边排样的冲件精度在IT11～IT9级之间，料厚t＞4mm的冲件，尺寸精度会更低一些。

In each step the tangent plane of limit state surface at the previous iterative point is calculated firstly, and then a line from origin to a point on the plane is determined whose intersection with limit state surface satisfies the requirement of feasible direction and convergence.

算法在每步迭代中先计算极限状态曲面在前步迭代点处的切平面，然后在此切平面上选定一个点，使该点和原点的连线与极限状态曲面的交点满足可行方向和收敛的要求。

Based on the geometric expression of the NURBS curve, a simple and effective method of curve and surface extension is put forward, and the blade surface is then successfully extended with the tangent vector by repeatedly applying the above method.

根据叶片的形状特征，以曲线的几何形式为基础，提出了一种简单实用的曲线曲面延伸方法，实现了切矢量连续的叶片型面的延伸。

Second, a nonuniform bilateral filtering algorithm for point set surface and surface attributes is developed, in which the tangent shift of points is avoided. The algorithm can be applied when points are sampled nonuniformly.

其次提出了基于双边滤波对曲面和定义在曲面上的函数的非一致双边滤波算法，该算法不仅避免了滤波过程中点的切向漂移，而且考虑了点采样的密度使得算法可以适应非均匀采样。

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。
