切线

Transition piece ; development ; approximate tangent surface

变形接头；展开；近似切线曲面

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。

In Particular, the tangent stiffness matrix in the incremental relation becomes symmetric, ensuring the efficiency in the numerical analysis, whereas the integrated constitutive relation serves as a guide, ensuring the convergence on the physically feasible stress strain relation.

值得一提得是，增量本构方程中的切线劲度矩阵是对称的，使得在进行数值分析时十分有效。而全量本构方程作为确保实际可行的应力应变滞回圈收敛的向导。

Any modification to the surface was simply a matter of dragging the vertices and the tangency handles.

针对表面所作的任何修改只是简单的托拽顶点和切线手柄。

The tangency align and curvature continuous constraints allowed us to quickly assess alterations in surface quality while retaining a smooth transition.

切线对齐和曲率连续约束允许我们迅速的评估表面的更改质量和平滑变换。

The point on a curve where the tangent changes from positive on the left to negative on the right.

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。
