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？原來較早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，新疆的起重軌。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，新疆的起重軌。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，新疆的起重軌。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。上海的起重軌低價資料。新疆的起重軌</p><div

2009年11月，廣安門站被拆除，中國鐵道博物館的**們在搶救文物時，發(fā)現(xiàn)了一批珍貴的近代鋼軌，這些鋼軌絕大部分是外國制造的，標注的生產(chǎn)年代大部分是20世紀初，其中一根所鑄銘文為 “造廠鐵陽漢1902” （1902年漢陽鐵廠造）的鋼軌引起了**們的極大興趣。漢陽鐵廠是中國近代創(chuàng)辦的***個鐵廠，也是當時亞洲比較大的鋼鐵企業(yè)，而 “1902”表明這根鋼軌是中國現(xiàn)存**早的國產(chǎn)鋼軌。**們?nèi)绔@至寶，把它完整地珍藏在中國鐵道博物館中。哈密的起重軌低價資料。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="新疆的起重軌,起重軌"

這就是路徑依賴，看起來有幾許悖謬與幽默，但卻是事實。經(jīng)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(chǎn)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。

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，而這些隧道的寬度只比火車軌道的寬度寬了一點點，然而我們不要忘記火車軌道的寬度是由馬的屁股的寬度所決定的。因此，我們可以斷言：可能***世界上**技術的運輸系統(tǒng)的設計，是兩千年前便由兩匹馬的屁股寬度決定了。新疆的起重軌</p><p
