Effect of mould electromagnetic stirring on central carbon segregation of heavy rail steel concasting bloom 15凹模环形裂纹电磁热局部跨越止裂的模拟研究
Provides services for short trips where the low speed is unimportant and the low fare is a major advantage . may feed heavy rail 提供短程服务，主要优点为票价低廉，低速度并不重要；可接驳重型铁路

5 . 13 on capacity , environmental and operating cost grounds , heavy rail should be at the top of the public transport hierarchy 5 . 13从载客量、环境及营运成本的角度考虑，重型铁路应居于公共交通级别之首。
The operating costs are still low by absolute standards , but are around double those of heavy rail per passenger - kilometre 在营运成本方面，以绝对标准来衡量，轻铁仍属廉宜，但以每公里每名乘客计算，则差不多是重型铁路的两倍。

5 . 7 heavy rail , as represented by the mtr and the kcr , provides a high - capacity , off - street , less - polluting , relatively accident - free service 7由地下铁路及九广铁路提供的重型铁路，不但载客量高，而且不占用路面，造成的污染较少及意外率极低。
At the top of this hierarchy comes the heavy rail system , which is capable of carrying large numbers of passengers at low marginal cost , and with low adverse environmental impact 在级别中居于顶级的是重型铁路系统，因为铁路能够以低边际成本载运大量的乘客，且对环境损害较少。

The secondary refining technology of steel for heavy rail has been comprehensively discussed in view of processes , equipment and automatic control , which provides valuable references for the production of the steel for heavy rail 从工艺、设备、自动控制等方面对重轨钢的炉外精炼技术进行了较全面的论述,对重轨钢铁生产具有较好的参考价值。
