利用几何成形的方法，推导了适用于摆动型热卷箱和非摆动型热卷箱辊缝调整的数学模型，并在此基础上提出了热卷箱卷取过程中上弯曲辊上抬速度控制的数学模型。

Because of the asymmetry of the inlet structure and the unstable characteristics of the swirl flow,the spinning center of the gas flow deviated from the geometrical center of the cyclone,which resulted in the asymmetry of the flow field and the change of the three dimensional velocity components.

蜗壳式旋风分离器入口结构的非轴对称以及气相旋流的不稳定性造成了气流的旋转中心与旋风分离器的几何中心不重合，从而导致了气相流场三维速度的非轴对称分布以及速度分量由于基准不同而产生的大小和方向变化。

Geometrical and physical parameters of components of the absorber in the virtual prototype follow from those technical data of a specific passenger car. Bench tests are conducted and a series of experimental results have been obtained by the MTS absorber test machine for the damping force-velocity which can be imposed in the virtual prototype for dynamic simulation. The piecewise, the hysteretic looped and the abnormal looped hysteretic force-velocity curves for the absorbers are, respectively, input into the prototype.

减振器阻尼力—速度特性是根据MTS减振器特性试验机试验结果，通过分段拟合，分别以分段线性、迟滞环和迟滞环畸变情况输入虚拟样机进行仿真分析，试验及仿真结果比较说明：减振器速度外特性采用迟滞环非线性，比采用双线性化模型更接近试验结果，能够更合理地解释试验现象；减振器阻尼力速度特性曲线出现畸变，如在复原行程初期迟滞特性曲线出现交叉现象，可以引发减振器系统动力特性的高频振动成分增加。

This paper presents two methods to estimate the relationship between dent depth and contact force, respectivelyβamend method and deflection compensate method, which are developed by using a clear geometrical relation to express indent, incursion profile and deflection difference.

本文以一种新的观点，用一个明确的几何关系来确定压痕、压头与板的接触面剖面及接触中心点与边界点之间的挠度差三者之间的关系，提出两种近似预测接触力与压痕深度关系的方法——β修正法和挠度补偿法。

For geometrical propositions are one and all apodeictic, that is, are bound up with the consciousness of their necessity; for instance, that space has only three dimensions.

几何命题都是矛盾性证明的。因此这些命题取决于对他们必然性质的理解。比如空间的三纬性。

For geometrical propositions are one and all apodeictic, that is, are bound up with the consciousness of their necessity; for instance, that space has only three dimensions.

因为几何学的定理全都是无可置疑的，亦即与它们的必然性的意识结合在一起的，例如空间只有三种量度；但这一类定理不可能是经验性的命题或经验判断，也不是从这些经验判断中推出来的。

For kindred reasons, geometrical propositions, that, for instance, in a triangle two sides together are greater than the third, can never be derived from the general concepts of line and triangle, but only from intuition, and this indeed a priori, with apodeictic certainty.

就连所有几何学原理也是如此，例如在一个三角形中两边之和大於第三边，就绝不是从关於线和三角形的普遍概念中，而是从直观中，并且是先天地以无可争辩的确定性引伸出来的。

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。
