Not only does the rolling stock require maintenance but also trackwork, traction power equipment, signalling, communications equipment, fare collection systems, electronics of all types and buildings maintenance.

不仅是对车辆的维修，还要对轨道、牵引供电、信号、通信、售检票、各种电子设备和建筑物等系统进行维护。

The main lithologic characteristic is that the rock types are dominated by light-colored clastic rocks reflecting the oxidation environment with a low maturity. The grain size distribution and sedimentary structure show that the rocks have the sedimentary characters of both gravity currents and tractional currents. Plant fragments are lacking and bioturbation structures are abundant and cyclic. Sandbodies are distributed in a ring shape.

其主要岩性特征为：岩石类型以反映氧化环境的浅色碎屑岩类为主，成熟度较低，粒度分布和沉积构造反映其兼有重力流和牵引流的沉积特点，植物碎屑贫乏而生物扰动构造丰富且具周期性，砂体呈环带状分布。

On the basis of engineering experience,the construction technologies for translatory moving by gasbag,transportation by semi-submerged and intallation of caissons are discussed.

结合某码头工程施工的实际情况，对沉箱气囊平移出运、半潜驳运输及安装的施工技术进行探讨，对出运气囊的布置、顶升气压计算、牵引系统布置及沉箱下水滑动安全验算进行了详细介绍，并提出保证安全与质量的计算模式和措施

In the development of the power rice transplanter in our country a single steel traction wheel is usually used.

我国的机动插秧机在发展过程中人们认为：采用独轮牵引式好。

Before the internal trifocal distractor was embedded, the remain dentition was performed inter maxilla fixation in order to keep the occlusion of the normal side.

分别在下颌骨缺损区两骨断端采用截骨术制作2块宽约1.5cm、高约3cm的骨牵引传送盘，最大限度保护传送盘骨块的软组织附着。

Gear rotation is a main rotation fashion of coal winning machine.And the rotation of engine unit and cutting unit is uniflow gear rotation.It is a main task for designer to improve the rotation character and carry ability of gear.

齿轮传动是采煤机械的主要传动方式，无论牵引部和截割部的传动均为单流齿轮传动，如何在不加大制造成本的情况下，改善齿轮传动特性，提高承载能力，是采煤机设计者的主要任务。

By torque split method and combination of a full-toroidal variator, an epicyclic gear train and a fix-ratio gear, the full-toroidal traction IVT is capable of changing the reduction gear ratio up to plus infinite or minus infinite.

摘要牵引式全环面无限变速器是采用转矩分流方法，把全环面可变耦合器与行星齿轮机构及定速比齿轮机构结合起来，其减速比可以达到正无穷和负无穷，即变速时输出轴可以由正转经零转到反转，因而命名为无限变速器(Infinitely Variable Transmission，简称IVT)。
