  1. In our country, many railway lines which were built in mountainous area have heavy gradient and curves with small radius. so it is difficult to improve them and a great amount of cost is needed in the modification of them

    由於我國幅員遼闊，有相當多的鐵路處于山區，線路坡度大、曲線半徑小、建設標準低，如果按照三大幹線標準改造線路使之適應提速要求，鐵路的改建很困難，所需人力物力不亞于修建新鐵路，不適合我國目前的國情。
  2. Among railway line ' s plane design parameter, the minimum radius of curve, transition curve ' s type and length, straight line between two curves, centre - to - centre distance of track are key factors which confine railway to bringing up speed, moreover these factors among maglev railway request even more strict

    由於高速磁懸浮鐵路採用了非接觸式的行車技術，舒適性將得到很好的改善。鐵路線路平面設計參數中，最小曲線半徑、緩和曲線長度、夾直線長度、線間距離是限制列車速度的關鍵因素，高速磁浮鐵路同樣如此。
  3. Side wear of rail on curves is a normal phenomenon in railway engineering. a great quantity of rail wear results in decreasing rail life in use and increasing railway transportation costs

    鋼軌側面磨耗是工務工程中普遍存在的問題，大量的鋼軌磨耗縮短了鋼軌的使用壽命，增加了鐵路運營成本。
  4. The railway track wound in and out among the passes, now approaching the mountain sides, now suspended over precipices, avoiding abrupt angles by bold curves, plunging into narrow defiles, which seemed to have no outlet

    本文首先從我國路網干線的現狀、客貨運輸的特點，指出了減緩曲線鋼軌側磨對於我國鐵路具有的現實意義，同時介紹了國內外關于輪軌磨耗研究的發展現狀。
  6. In our country, many railway lines which were built in mountainous area have heavy gradient and curves with small radius

    由於歷史的原因，我國大部分既有線路，特別是中、西部的既有線路等級不高，基礎條件差。
