Whether it is from the passenger or freight to rail transportation equipment safety and stability as the basis for a strong backing. But according to the Chinese conditions need to adapt to the study, if theequipment is not practical in our country new from existing equipment, undoubtedly hindered the development of our country. So we should choose a suitable for China and can enhance our railway transport path is very good. The introduction of France39。s railway transport situation. 北京交通大學本科論文 3 目 錄 中文摘要 ........................................................................................................................ 1 英文摘要 ........................................................................................................................ 2 1 緒論 ............................................................................................................................. 5 2 ZPW20xxA 無絕緣軌道電路 ............................................................................ 5 ZPW20xxA無絕緣軌道電路 系統(tǒng)構(gòu)成 ..................................................................... 5 .............................................................................................. 6 .............................................................................................. 6 ................................................................................................................. 6 ........................................................................................................ 6 ........................................................................................................ 9 ........................................................................................................ 9 .........................................................................................10 ................................................................................................................10 ....................................................................................................10 ................................................................................................10 ..................................................................................10 ....................................................................................................11 ３ ZPW20xxR 無絕緣軌道電路 ......................................................................... 11 ZPW20xxR無絕緣軌道電路 性能與特點 .................................................................. 11 ZPW20xxR無絕緣軌道電路特點 .................................................................11 ....................................................................................................11 ....................................................................................................11 ................................................................................................................ 11 .............................................................................................11 ....................................................................................................12 ................................................................................................13 ...............................................................................14 .............................................................................................14 斷軌檢查 .............................................................................................15 斷線檢查 ......................................................................................15 ....................................................................................................15 ....................................................................................................16 北京交通大學本科論文 4 .........................................................................................................16 .......................................................................................................16 .......................................................................................................16 .......................................................................................................16 ................................................................................................17 .............................................................................................17 .............................................................................................17 ....................................................................................................17 .....
