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，烏魯木齊起重軌廠家，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，烏魯木齊起重軌廠家，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，烏魯木齊起重軌廠家，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(yīng)該完結(jié)了，但事實上還沒有完。內(nèi)蒙古的起重軌現(xiàn)貨。烏魯木齊起重軌廠家</p><div

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。 </p> <p> 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(shè)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(shè)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？阿勒泰的起重軌現(xiàn)貨。烏魯木齊起重軌廠家</p><p
