查询词典 track record

Research conclusions:The analysis and comments are made on the requirements and the technical indexes of rail, sub - rail foundation, fittings and ballast bed for track structure of passenger dedicated railway line and high - speed railway in many countries, and the thinking is offered for development of the key track technologies

研究结论：对各国在高速铁路轨道结构、客运专线和高速铁路对轨道结构的要求、钢轨、轨下基础、扣件、道床等方面的技术指标做出分析和评述，并对一些关键技术的发展提出了思路。

With the speed of trains running continuously improve, the ballast track ballast of the powder, bed and the cumulative result to speed up the rate of deformation, it is necessary to strengthen the track structure and frequent maintenance work to meet the high-speed railway line on the high ride comfort, stability Requirements.

随着列车运行速度不断提高，有碴轨道的道碴粉化及道床累积变形的速率随之加快，必须通过轨道结构强化及频繁的养护维修工作来满足高速铁路对线路高平顺性、稳定性的要求。

The comparison to the interferential voltage in ballast track shows that the steel bar net of ballastless track enlarges the rail current proportion in traction current in certain degree, which raise the rail interferential voltage from the traction current slightly.

与有砟轨道的干扰电压进行对比分析的结果表明：无砟轨道钢筋网络在一定程度上增大了钢轨回流在牵引回流中的比例，使得牵引电流对轨道电路的干扰电压略有增大。

Ballastless track features little maintenance,high reliability,long service life,low cost compared to its service life, low structure height, large transverse track resistance, ballast splashing—proof,and flexible superelevation and gradient.

由于无碴轨道具有维修量小，稳定性好，使用寿命长，全寿命周期费用低，结构高度低，横向轨道阻力大，可避免飞碴，超高、坡度设置灵活等优点，在德国高速铁路建设中受到重视，得到了广泛应用，并形成了Rheda、Zt~BLIN、BERLIN、B6GL等系列产品。

Improvements in track technology (i.e., Roller Chain Band Track) and decoupled running gear have decreased noise signatures for tracked vehicles, but not to the level attained by wheeled platforms.

虽然目前履带车辆在采用了一些新型的履带和吸振的路轮后噪声有明显的下降，但是相比之下还是远远高于轮式车辆。

In months of extensive track testing our HB race team and engineers have developed what we think is the finest off-road suspension geometry available today: wide track suspension arms, inverse steering block design, vertical ball end placement and of course full adjustability to name just a few highlights.

在几个月的广泛赛道测试我们的血红蛋白车队和工程师们开发的是什么，我们认为是最优秀的越野道暂停几何可今天：宽轨道暂停武器，逆督导座的设计，垂直球头的安置和当然充分调节的名字，只是几个突出。

Here we will suppose that without a body on the alternate track, the trolley would, if turned that way, make its way to the other track and kill the five people as well.

在这种情况下，是否应该把电车引向站着一个人的轨道去压死他？

This answer, however, runs into trouble with a variant of the trolleyconnect with the track leading to the five people (1). Here we willsuppose that without a body on the alternate track, the trolley would

那么我们再来看一个&电车难题&的变型：假设站着一个人的那条轨道的另一端是跟另一条轨道相连的，即形成一个回路，如果那上面没有这个人，电车会从这条
