查询词典 rail track

Since the signal equipments imported is unable to meet the development demand of urban rail transit, independent research of the domestic digital jointless track circuit is critical. Charateristic analysis for signal transmission of digital jointless track circuit was mainly studied in this thesis. Design digital jointless track circuit analysis software, which validated the transmission parameters could or not meet requirements of the normal, shunt and signaling states, was the key work of the research.

In order to adapt this requirement, the new laying track must be rectified preventively and the online use rail must be grinded for removing inherent defect in track and surface unsmooth-going and fatigue damage layer of track.

为了适应这种提速的要求，必须对新铺设的钢轨进行预防性修磨处理，并对在线使用的钢轨必须进行修磨，从而消除钢轨中固有的缺陷、钢轨顶面的不平顺以及钢轨焊接头的不平顺和钢轨的疲劳破坏层。

Carmody said the track is a continuous welded rail, and ''heat can be a factor and cause a slight misshaping or buckling in the rail.

Carmody说，铁轨是一段段焊接起来的，因此&天热可能是一个导致铁轨轻微变形或弯曲的因素&。

Therefore, since the early 1960s, countries around the world have been carried out to the overall rail-bed, or curing alternative granular ballast of the various Ballastless track structure of the system, some countries have Ballastless track as the main high-speed railway Track structure of a comprehensive application.

因此，自上世纪六十年代初，世界各国铁路相继开展以整体式或固化道床替代散粒体道碴的各类无碴轨道结构的系统研究，一些国家已把无碴轨道作为高速铁路的主要轨道结构型式全面推广应用。

With the harmony between vertical and lateral deformation of long rail components taken into account, a transition locking structure for large expansion volume, an ending structure of the switch, a nose rail that both transfers longitudinal force efficiently and maintains turnout regularity, and a fastener system suitable for both ballast and ballastless track were developed to solve the transition choking problem of jointless turnout.
