A person trudges in the mire to need to be lead,a person falls to bump the desire candlelight in the twilight, in I work the career, I my mother is most touched, Make me raise life self-confident sail of boat under her encouragement and the inspiration. I will express the feeling to the respect adore of mother by own emotion.

一个人跋涉在泥泞中需要牵引，一个人跌撞在暮色里渴望烛光，在我的打工生涯中，我最感动的是我的母亲，在她的鼓励和感召下，使我扬起了人生自信的风帆，我将以自己的情感抒发对母亲的崇敬之情。

With the uprising movement of Chinese railways and progress of electric railroad, the small tonnage full hydraulic railway crane becomes more urgently needed for development with characteristics of fast speed self-propelled running and high speed in train formation, hence, the high level requirement is resulted in terms of train formation and self-propelled running speed of railway crane. For 20t universal railway crane, features such as running with the load and weight lifting due to high hauling capacity are required besides hook lifting, bucket grabbing and magnetic panel lifting.

随着我国铁路事业的不断壮大，电气化铁路的发展，开发小吨位的自力走行速度快、回送速度高，能满足电气化线路的立杆作业的全液压铁路起重机迫在眉睫，对铁路起重机的回送和自力走行速度有了更高的要求。20t多功能铁路起重机，即具有吊钩、抓斗、磁盘吊3种功能外，还具有一定带载走行以及因牵引能力大也可作为吊车机使用。

The computation model of two-point contact (for cone-tread) and conformal contact (for worn-tread) resulting from wheel flange close to rail is firstly established in this paper. A detailed analysis is made of the wheel/rail contact force, contact status and wheel/rail stress distribution on the different action of tractive forces and transverse forces. We draw some important conclusions, one of which is that the locomotive adhesion performance will decrease with the increase of transverse forces between wheel and rail.

本文建立了车轮轮缘贴靠钢轨形成的轮轨两点接触和共形接触的计算模型，对不同的牵引力矩、不同的横向力作用下的轮轨接触力、接触状态和轮轨应力分布进行了详细的分析，得出了轮轨间横向力增大会降低机车粘着性能等一系列重要结论。

Just like a frog dragged by the crab from the East Sea out of the deserted well, facing such a vast ocean, I was much shameful for having been content and proud to live in so narrow a well, for the real endless ocean was what I had longed for, so my heart got boiling and swelled by the surfing sea...

我像是化为了一只井底之蛙在东海之螯的牵引下跳出废井，面对大海，我惭愧不已。回想自己满足于如此狭小不堪的枯井还自以为是，然而真正的博大，浩瀚无垠的海洋才是我的向往。我的胸中沸腾了，弥漫着鼾息声的大海将我的心膨胀。。。。。。

Away to the southeast, far beyond the limits of Erchester and the headlands above the Kynslagh, a deep gray mark was smeared across the clear Marris sky, as if a dirty thumb had been dragged across a newly-painted wall.

东南方的远处，比Erchester地方更远，比Kynslagh湖的陆岬更高，Marris月的清澈的天空上，横跨一大片深灰色的痕迹，好象是一只脏拇指被牵引着，划过一面新刷好白粉的墙。

The muscles, not spontaneously moved but moved by a low usurping wilfulness, grow tight about the outline of the face, and make the most disagreeable sensation; a sensation of rebuke and warning which no brave young man will suffer twice.

其面部肌肉不是自然地运作，而是爲一种低下的、处心积虑的抽搐所牵引，肌肉在面庞外围绷得紧紧的，给人一种最不愉快的感觉：一种受责备和警告的感觉。这种感觉，任何勇敢的年轻人都绝不会愿意体验第二次。

Simply put, is to see a fundamental traction as the main line, and then use many different volumes as a subcarrier, although the description in the story is the same person, but the volume of each style are completely independent, however, These elements have a common goal is to the protagonist of a new life.

简单的说，就是，以一条根本看不见的主线作为牵引，然后用很多不同的分卷作为载体，虽然描写的是同一个人的故事，但是每一卷都是完全文体风格独立的内容，不过，这些内容都有一个共同的目标就是——给主角一个新的生命。

And with that the scientists began to lead the Sentinels on a circuitous tour through the dome, descending always, via tractor tubes and spiral drops where there should have been stairs, past conveyor systems and vat after vat of Fruits or pulverized stem and Flower, in and out of corridors and rooms, commo stations and rotundas, all recently vacated by soldiers and worker drones who had ceased their tasks to protect the farm.

随即被俘虏的因维科学家开始带领哨兵们以一段迂回的行程穿越母巢的穹顶：经由牵引通道和螺旋坡道一直往下——这些地方本应该有楼梯的；穿过输送系统以及一桶接着一桶的奥普特拉树木果实或是被研磨成粉的茎干和生命之花；出入各种走廊、房间、通信站台和圆形厅室，所有这些地方都空无一人，因为不久前因维士兵和机器工人们都放下手中的工作去保卫农场了。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
