He is friendly, after he save life of returning the first lieutenant, the first lieutenant which loses legs always can't die in battle to on the battlefield but still drag out a shameful existence by the 躯 of physically disabled to oneself but 郁郁 not 欢;Because first lieutenant is so a kind of person:he sees honor high in everything, he can't suffer ordinary, is sweet call to return to his confidence to life with the amicability, make him discover, there are even no legs,The life still can be filled with source of vitality.

他友善，在他救回中尉的性命后，失去了双腿的中尉一直对自己不能战死在战场上却仍以残废之躯苟且偷生而郁郁不欢；因为中尉是这样一种人：他视荣誉高于一切，他不能忍受平凡，是阿甘用友善唤回他对生命的信心，使他发现，即使没有双腿，人生依然可以充满生机。

Although Cornwallis's defeat did not immediately end the war -- which would drag on inconclusively for almost two more years -- a new British government decided to pursue peace negotiations in Paris in early 1782, with the American side represented by Benjamin Franklin, John Adams and John Jay.

虽然 Cornwallis 的失败不立刻结束战争--哪一个会非决定性为几乎另外二个拖延数年--一个新的英国政府决定早的 1782 在巴黎追求和平谈判，藉由被班杰民富兰克林，约翰亚当和约翰鸟表现的美国边。

A three- dimensional turbulence model in non-orthogonal curvilinear coordinates is proposed to investigate the impacts of vegetation on channel morphology. The model includes vegetation-induced drag force and vegetation density in the control equations to describe the effects of vegetation on flow structure, and solves sediment continuity equation to compute channel geometry.

本文建立曲线坐标系下的三维湍流模型研究水生植物对河道形态的影响，在水流控制方程中加入植物阻力项和植物密度项来描述水生植物对水动力特性的贡献，通过泥沙质量守恒方程求解河道变形，在适体网格中求解模型的控制方程。

If the air drag and composite motion are considered in the analysis of the balloon yarn in ring spinning,the calculation with the circular cyclindrical coordinates is simpler and more precise.

在环锭纺气圈的分析中，用柱面坐标系计算能简明、清晰地反映空气阻尼力、复合运动诸因素的综合影响。本文介绍了根据照相测量的气圈形态参数计算纱线张力的新方法

In this configuration a small highly swept delta wing is added in front of the main wing for reduced drag at low speeds.

这种外形是在主翼前加上大倾角的三角翼，以减少在低速时的劣势。

To download the uploaded file is more simple, just select the files to be downloaded to your computer directly drag and drop the corresponding location of the saved; of course, can also right-click to directly download the file, in the pop-up menu, select "download" command, in the open window select the directory you saved.

The results show that the camber deformation may play an important role in lift and drag coefficients. The positive camber deformation of the hindwing during the downstroke generates the vertical force, whereas negative camber deformation of the wing during upstroke generates thrust force. The freely flying dragonfly's hindwings play an important role in providing a stable lift force, and the forewings are very important for controlling flight behavior, such as turning, climbing and so on.

建立了自由飞行昆虫运动测量系统，开发了结合条纹投影和昆虫翅膀特征点测量翅膀变形和身体姿态的方法，首次测到了自由飞行昆虫运动翅膀变形和各种相关角度，速度、加速度，身体位置与姿态，通过分析比较直飞和转弯各个运动参数，认为蜻蜓的飞行控制主要由前翅完成，而后翅主要用于产生升力。
