In chapter six, A finite element model to evaluate the mechanics properties of thin wall structure is put forwards. The 4-node quadrilateral Hughes-Liu shell element with five through-the-thickness integration points is employed. The material is assumed to satisfy the elastic-plastic yield condition with isotropic hardening. The single surface contact algorithm is taken to deal with the contact searching. The priori stabilization procedures for the numerical control of the hourglass instability and the penalty method for the evaluation of contact force are used. The classical Coulomb law of friction is employed to evaluate the friction force.

第六章采用法向方向5点积分的4节点Hughes-Liu壳单元，前置参数法砂漏控制技术，等向强化弹塑性材料模型，分步增量应力回映方法，一体化接触搜寻算法，罚参数接触力计算方法及经典摩擦定律，建立了一种计算受冲薄壁结构大变形力学特性计算的有限元模型，通过对汽车A传动轴及汽车纵向方形吸能梁的大变形力学特性分析，验证了该有限元模型的正确性。

Instead, Kachin leaders have proposed a Kachin Regional Guard Force in place of a government-backed border guard force.

相反，克钦族领导人提出了一个政府设立一个克钦地区卫队支持的边防力量。

An imaginary line in a field of force; direction of the line at any point is the direction of the force at that point.

力场上理论想象线；任一点的切线指向那一点的力场方向。

Moving electric charges in a magnetic field experience a force that is perpendicular to both their direction of movement and the magnetic field, called the Lorentz force.

运动电荷在磁场中的经验，一支是垂直两个方向的运动和磁场，称为洛伦兹力。

The new form of Lorentz Force Formula,that will be suitable for the charge at any speed,has been derived,and it can be transformed into the general Lorentz Force Formula in any case at lower speed.

并在此基础上导出了适用于任意速度的新的洛伦兹力公式，它在低速情况下转化为通常的洛伦兹力公式。

When charged particles move in the magnetic field, they will experience an electromagnetic force called Lorentz force which is orthogonal to both the direction of velocity and magnetic field.

当带电的粒子在电磁场中运动时，会感受到电场与磁场的作用力，这个电磁力垂直於粒子的速度以及磁场方向。

The equation of magnetic line of force for current element is derived and the concluion is obtained that any magnetic line of force is a close circle and its center changing in straight line on three coordinate plane, the oblique rate is determined by current element.

导出了电流元的磁力线方程，发现任一磁力线是一闭合圆线，圆心在三个坐标平面上沿直线变化，斜率由电流元的取向决

Based on the mechanical phenomena appeared in the experiments,put forward three suppositions about magnetic line of force named repellency among lines,least resistance route property and amount limit property when magnetic line of force penetrates ferromagnet.

依据实验中电磁、永磁两种元件同极间的力学现象，提出了关于磁力线性质的三个假说，认为磁力线具有线间斥性、最小阻径性和磁力线通过铁磁质时的容限性。

Then the chemical reduction of[Ni(N_2H_4)_x]~(2+) may occur along the magnetic line of force due to the enhanced electrode potential,leading to the formation of uniform 1 D wires.While with the increase of the concentration of Ni~(2+), the reaction rate increases too,so it can be deduced that the chemical reduction of [Ni(N_2H_4)_x]~(2+) may be taken place quickly in the whole system,leading to the formation of isolated particles coexisted with the wires composed of microspheres which formed along the magnetic line of force.

而当Ni~(2+)浓度较高时，反应速率相对较快，[Ni(N_2H_4)_x]~(2+)可能在还没来得及迁移到磁力线之前，还原反应就已经很快的在整个体系中发生了，导致出现了产物中纳米球和一维镍线共存的现象。

In this paper, the system construction of a micromanipulation robot based on hybrid control of micro-vision and micro-force was introduced, and the micro-vision system and micro-force system and their principle were described.

简单介绍了一种基于显微视觉和微力觉柔顺混合控制的微操作机器人的系统构成，并重点介绍了显微视觉系统和微力控制系统的组成及工作原理。

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。
