牵引

The train is then stopped and the overhead leads removed. The leading car is then used to drag the rest of the train out of the shed. Care has to be taken to ensure all leads are removed before allowing a train to leave the shed and enter service.

然后列车要停下来，将悬吊线解下，由第一节车牵引列车出库，在列车离库进入运用前，必须确认所有的悬吊线都从车上解下。

First, it diagnoses and analyses the maglev train's suspension system and traction system by applying the FTA and fuzzy FTA method. Furthermore, it presents the new way to solute the diagnosis searching arithmetic by building the searching matrix based on the factors such as components' key weightiness, faults happen probability, searching cost. Then it can get optimal searching sequence for seeking the reason to the faults. Second, it builds the train's rank evaluation model based on multiple hiberarchy neural networks, after it takes the strategy that set the component diagnosis and whole train fault rank evaluation into two steps. Third, it deeply analyses reliability of the maglev train's power system with function-correlated feature, by the method that combining the FTA with the Markov model. Finally aiming at maintenance ahead of the fault, it proposes the blue print for the maglev train's maintenance. What's more, it introduces the design and realization to recorder for the train run data in detail.

应用故障树和模糊故障树分析法对磁浮列车悬浮系统、牵引系统进行全面的诊断分析，提出了以部件关键重要度、故障概率、搜索代价为因素，建立搜索决策矩阵，综合排序的搜索算法；采取部件诊断和列车集中评估相结合的分层诊断策略，建立基于多重神经网络的列车故障等级评估模型；结合故障树和马尔可夫模型对具有功能相关特性的列车电源系统进行可靠性分析；着眼事前维修，提出了列车运行维护方案，并设计实现了列车运行数据记录器。

Montrail sandwiched a protective yet flexible Trail Shield plate in between the Masochist's sticky Gryptonite rubber outsole and triple-density Vapor Response EVA mid sole, so you get the most functional blend of traction, protection, and comfort.

Montrail夹心保护而灵活的步道板的盾之间的受虐狂的粘性Gryptonite橡胶外底和三重密度气相反应长荣唯一中旬，所以你获得最大的功能结合牵引，保护和舒适。

被汽车﹑电车﹑拖拉机等牵引着走的车箱。2。一种脚踏拖动的运货车。有三轮拖车和四轮拖车。速度较手拉的运货车快，而且灵活。他们把食物和野营用具都装上拖车上了。

The engine was to drive a single tractor propeller and it was to have a wheeled landing gear.

引擎驱动牵引式螺旋桨，并配有轮式起落架。

A lot of research work has been done on the improvement of small wheel tractor traction performance in recent years.

近几十年来，国内外许多学者、专家对如何提高拖拉机的牵引附着性能作了大量的研究，取得了较好的效果。

"Traction Avant" means Front Wheel Drive.

&牵引先锋&是指前轮驱动。

With the development arise some problems of the wheel/rail performance, the requirement of the train traction for the adhesion of wheel/rail will become more and more strict, and rail corrugation of wheel/rail, rolling contact fatigue and derailment will become more and more serious. The solution to the problems will have direct effects on the railway development.

当前世界铁路正朝着高速和重载的方向发展，随之而来的是列车牵引对轮轨粘着的要求越来越高，而轮轨的波浪形磨耗、滚动接触疲劳、脱轨等轮轨关系问题越来越严重，其解决与否直接影响到铁路的快速发展。

The traction ability of the driving wheel on simulant regolith is similar to but slightly better than that on quartz sand; when the slip ratio is 10%, the DPs on simulant regolith and on quartz sand are 36.8 N and 33.1 N respectively.

驱动轮在模拟月壤和石英砂上的牵引性能相似，前者略好于后者，当滑转率为10%时，挂钩牵引力分别为36.8 N和33.1 N。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
