1·The guide way is communicated with all the track lead rails connected with the redirector.
导向轨与连接转向器的每一条轨道导轨之间相互连通。
2·The guide for the hold-down plate moving up and down is near to the lead rails in two sides. The good guide effect ensures the parallelism of upper and lower working sides.
板上下运动的导向靠两侧导轨，导向效果较好，保证了上下工作面的平行度。
3·The diving chamber is a watertight compartment with air pipes, the lifting support is a girder structure, and the lead rails are arranged under and below the lifting support;
潜水舱是带有通气管的水密舱，升降支架为桁 架结构，升降支架的上下设有导轨。
4·I coauthored RailsSpace, a best-selling Rails tutorial book published in 2007, and was cofounder and lead developer of Insoshi, a popular social networking platform in Ruby on Rails.
我跟人合写过RailsSpace这本书，2007年出版的，曾经在Rails指南类图书中名列前茅。我跟人一起创立了Insoshi，它是用RoR开发的一个比较流行的社交网络平台，我还是其中的技术领导。
5·These are graphite, high silicon cast iron, lead silver alloy, platinum, and even scrap steel rails.
所用材料有石墨、高硅铸铁、铅银合金、铂、甚至废钢轨等。
6·Rust in the surface of the rail may lead to bad shunt circuit of rails.
铁路钢轨的锈蚀会导致轨道电路的分路不良。
7·C. Guide rail of impeller stopper adopts high hardness, good abrasion linear rails, and with small gap, high hardness ball screw lead, ensures stability and high precision for paper pushing. D.
推纸挡规导轨采用硬度高，耐磨性好的线性导轨，再配以间隙小，硬度高的滚珠丝杆，最大保证了推纸的平稳性和高精度性。
