經濟學中有個名詞稱為「路徑依賴」，它是類似於物理學中的"慣性"，一旦選擇進入某一路徑（無論是「好」的、還是「壞」的），就可能對這種路徑產生依賴。以下美國鐵軌的故事也許有助于我們理解這一概念，并且加深對其后果的印象。美國鐵路兩條鐵軌之間的標準距離是四點八五英尺。這是一個很奇怪的標準，究竟從何而來的？原來這是英國的鐵路標準，因為美國的鐵路**早是由英國人設計建造的。那么，為什么英國人用這個標準呢？原來英國的鐵路是由建電車軌道的人設計的，而這個四點八五英尺正是電車所用的標準。電車軌標準又是從哪里來的呢？原來**先造電車的人以前是造馬車的。而他們是用馬車的輪寬做標準。好了，那么，馬車為什么要用這個一定的輪距離標準呢？因為如果那時候的馬車用任何其他輪距的話，馬車的輪子很快會在英國的老路上撞壞的，新疆鋼材輕軌廠。為什么？因為這些路上的轍跡的寬度為四點八五英尺。這些轍跡又是從何而來呢？答案是古羅馬人定的，四點八五英尺正是羅馬戰(zhàn)車的寬度。如果任何人用不同的輪寬在這些路上行車的話，新疆鋼材輕軌廠，他的輪子的壽命都不會長。我們再問：羅馬人為什么用四點八五英尺為戰(zhàn)車的輪距寬度呢？原因很簡單，這是兩匹拉戰(zhàn)車的馬的屁股的寬度，新疆鋼材輕軌廠。故事到此應該完結了。福建的輕軌多少錢浙江的輕軌多少錢。新疆鋼材輕軌廠</p><div

開辦漢陽鐵廠的目的本就是為盧漢鐵路提供鋼軌，修建盧漢鐵路是一波三折，漢陽鐵廠的開辦更是困難重重。1890年5月，張之洞在武昌成立湖北鐵政局，經過親自勘察、反復研究和慎重考慮，張之洞決定將廠址建在漢陽大別山下。1891年9月，漢陽鐵廠破土動工，張之洞對建廠事務“躬親細務，錙銖必較，急如星火，日夜操勞”?？朔酥刂乩щy后，漢陽鐵廠于1893年年底完工，包括煉鐵廠、熟鐵廠、鋼軌廠、鋼材廠等10個分廠，蔚為壯觀，于1894年2月正式點火。但是，鐵廠剛開始投產就面臨一個**大的實際問題——資金不足。清所撥費用已全部用完，而投產所需資金至少100萬兩白銀。張之洞奏請朝廷，提出設備“分量、分撥”投產，以解決資金周轉問題，減少開工費。他還建議朝廷將建造湖北炮廠等工廠的資金“撥借”過來。緊接著，一個大難題接踵而來，由于缺乏經驗，前期技術準備不充分，所用的原材料大冶鐵礦砂和煉鋼爐不匹配，無法提取大冶鐵礦砂中所含高濃度的磷，造成試軋出的鋼軌質脆易裂，不能普遍使用，鐵廠經營陷入了困境。1896年，漢陽鐵廠改為官督商辦，張之洞舉薦盛宣懷接手，之后又對冶煉設備進行了重整改造，鋼鐵質量轉佳，經營銷售一度頗有生機。</p><p> 大有振衣千仞、一覽眾山之勢。”至于鋼軌的質量問題，鐵廠一直到1904年才徹底找到病根，軋出了完全合格的鋼軌。至辛亥**前，鐵廠年生產鋼軌約2萬噸，，它不僅向盧漢鐵路提供鋼軌，而且凡是盛宣懷組織的中國鐵路總公司督辦的鐵路均優(yōu)先購用漢陽鐵廠鋼軌。據估算，至1922年年底，漢陽鐵廠鋼軌所鋪設的鐵路占中國已建鐵路里程的1/3。1924年，漢陽鐵廠在經過了短暫的黃金期后，終因財政困難、外債沉重而全部停產。*****時期，**將鐵廠設備一部分遷至重慶，剩余的或被炸毀或被侵占。至此，承載著晚清“自強求富”希望的中國近代鋼鐵廠終究無法擺脫悲劇命運，黯然隕落。眼前的這根鋼軌所鑄銘文清晰可辨，**們雖無法確切考證出它是否在京漢鐵路或是其他早期鐵路上實際使用過，“1902”的年代信息是確鑿無疑的，至今為止國內還沒有發(fā)現過幸存的生產年代比它更早的國產鋼軌。伊犁的輕軌價格。。。</p><div

而這個四點八五英尺正是電車所用的標準。電車軌標準又是從哪里來的呢？原來**先造電車的人以前是造馬車的。而他們是用馬車的輪寬做標準。好了，那么，馬車為什么要用這個一定的輪距離標準呢？因為如果那時候的馬車用任何其他輪距的話，馬車的輪子很快會在英國的老路上撞壞的。為什么？因為這些路上的轍跡的寬度為四點八五英尺。這些轍跡又是從何而來呢？答案是古羅馬人定的，四點八五英尺正是羅馬戰(zhàn)車的寬度。如果任何人用不同的輪寬在這些路上行車的話，他的輪子的壽命都不會長。我們再問：羅馬人為什么用四點八五英尺為戰(zhàn)車的輪距寬度呢？原因很簡單，這是兩匹拉戰(zhàn)車的馬的屁股的寬度。故事到此應該完結了，但事實上還沒有完。下次你在電視上看到美國太空飛船立在發(fā)射臺上的雄姿時，你留意看，在它的燃料箱的兩旁有兩個火箭推進器，這些推進器是由設在猶他州的工廠所提供的。如果可能的話，這家工廠的工程師希望把這些推進器造得再胖一些，這樣容量就會大一些，但是他們不可以，為什么？因為這些推進器造好后，要用火車從工廠運到發(fā)射點，路上要通過一些隧道。新疆鋼材輕軌廠</p><p
