Hitherto, we had never been on such a long excursion,and we were all very much excited as we set out for the hilly expanse of thehinterland behind the river, up and down we walked all day, from hill to hollow.pleasant as the scenery was, the area was economically backward, with nothingmore than little homesteads, where small-time farmers would still be doingthings like mend the hinges on their barn doors, hoe the soil, hollow out somepiece of wood to make a simple tool or hoist the hay onto their carts byhand.

那之前，我们从来没有进行过如此长距离的远足，我们向河后面的内陆多山的广袤地域出发时，都非常激动。一整天，我们在山峰和山谷之间上上下下。虽然这个地区景色宜人，但经济落后，除了小农舍外没有别的，那里面，尚未脱贫的农民可能还在做着修畜棚上的铰链、锄地、挖空木头做简易的工具或徒手把干草吊到马车上之类的事情。

By the two steps, distract and correct the knee flexion at 0 degree to form knee joint with caput fibulae and lower femur and to fit the lower limb brace which can stahilize the knee joint after the llizarov apparatus is disassembled.

结论膝关节牵伸技术，可有效的矫正先天性胫骨缺如伴发的屈膝畸形，安装带膝关节铰链的牵伸器，可将腓骨头与股骨下端控制于中直位，在长期生理性行走应力的刺激下，腓骨发生了胫骨样的变化，可发育成具有类似膝关节形态的结构，整个患肢由于正常的行走使用而得到良好发育。

The purpose of the study is to develop a S-type flexural pivot for parallel motion mechanism.

本文目的在於将S型挠性铰链应用在平行机构之设计。

In airplane design, structural nonlinearities cannot be avoided. The structuralnonlinearities arise from worn hinges of control surfaces, loose control linkages,material behavior and various other sources. In the flighting, the aerodynamicnonlinearities also cannot be avoided. The aerodynamic nonlinearities can benegligible when the speed of the plan is not very high;but when the speed of the planis supersonic or highly supersonic, it cannot be negligible.

在飞机设计中，结构非线性是不可避免的，结构非线性源于控制其表面的旧铰链，松散的控制器联动装置，材料性能和其它的来源；在飞机的飞行中，气动的非线性也是不可避免的，对于飞行速度不是很高的情况，气动的非线性是可以忽略的，而对于超音速以及超高音速的飞机来说，气动的非线性是不可以忽略的。

After hears the yellow Jinlong commander in chief's order, already succeeded the hook to live this planetoid the starships, after passed through the very short time, had achieved with the planetoid the similar speed, likely the human rode in the acceleration the airship to be same, starts the anchor chain which back and forth vibrated this time already to pull taut, and started to maintain stably, all starship pilot, already not in the worry planetoid surface more than 1200 degrees high temperatures, the thick fog group which as well as raided intermittently, after received the order then the rapid start automatic hinge machine, to this planetoid superficial fast advancement, in order to set aside the enough debarkation space for the second interspace group,This time by far looks, the entire starry sky scene, looks like a big spider to lead only to creep along innumerably small spider such, has filled the mysterious visual effect, lets the human feel incomparably shocks!

在听到黄金龙总指挥官的命令后，已经成功钩住这颗小行星的星际飞行器们，在经过很短的时间后，就与小行星达到了同样的速度，就像人乘坐加速中的飞船一样，开始来回抖动的锚链此时已经绷紧，并开始保持稳定，所有星际飞行器的驾驶员，已经不在顾虑小行星表面1200多度的高温，以及阵阵袭来的浓雾团，接到命令后便迅速启动自动铰链机，向这颗小行星的表面快速推进，以便给第二星际小组腾出足够的登陆空间来，此时远远望去，整个星空场面，就像一只大蜘蛛带领着无数只正在爬动中的小蜘蛛那样，充满了神奇的视觉效果，让人感到无比震撼！
