The sun can make tracks disappear,and,when the tracks refreeze ,they look like large footprints,such as those on Mount Everest.

太阳能使轨道消失，和，当轨道再冻结的时候，他们看起来像大的足迹，像是在埃佛勒斯峰上的那些一样。

We were to take our spaceship in the vicinity of a pulsar and go into orbit around it and remain in orbit for two weeks during which time, the telemetric instruments on board the ship would record as much data as possible about the pulsar.

我们将驾驶飞船飞到一个脉冲星的附近，然后进入轨道。我们将依此轨道环绕两个星期。在此期间，飞船上的遥感勘测设备将记载尽可能多的脉冲星信息。

With the developing of Chinese railway industry, unballast track on the soil subgrade is used more and more widely, and the structure of unballast track on the soil subgrade is strictly required for the displacement and settlement.

随着我国铁路事业的迅速发展，土质路基无砟轨道应用日渐广泛，土质路基上的无砟轨道结构对下部基础的沉降和差异沉降提出了严格要求。

We further analyze the electronic transport spectra and the molecular orbits, and find that the LUMO+2 orbital 15 delocalized all over the extended molecule and provides a good channel for the electronic transport.

通过进一步分析电子输运谱图和分子轨道得知，该类分子的LUMO+2轨道具有较好的扩展性，为电子输运提供了良好的输运通道。

This research main of research the content aim at the system noise of the orbit conveyance namely it become grind to judge because of carrying on, and through analysis valuation, the draw-up derails the prevention and cure counterplan of orbit noise, and to part prevention and cure the result measurement of counterplan do an initial analysis ratio to, distinguish a counterplan and become because of theoretically and the result ratio on the actual situation to with provide the best project of noise prevention and cure.

本研究主要的研究内容即针对轨道运输系统噪音之成因进行研判，并经分析评估，拟定出轨轨道噪音的防治对策，并对部分防治对策的结果量测做一初步分析比对，厘清对策与成因在理论上及实务上之成效比对，以提供噪音防治之最佳方案。

But mass-construction of urban railway is still not practicable in most Chinese cities because of the too-much high cost of construction.

然而由于轨道交通的造价过于昂贵，对于目前我国大多数的城市而言，大规模发展轨道交通是不现实的。

It orbited around the sun across it paths with Neptune's.

它的以太阳为中心的轨道和天王星的轨道交叉。

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
