為什么英國(guó)人用這個(gè)標(biāo)準(zhǔn)呢？原來(lái)英國(guó)的鐵路是由建電車軌道的人設(shè)計(jì)的，而這個(gè)四點(diǎn)八五英尺正是電車所用的標(biāo)準(zhǔn)。電車軌標(biāo)準(zhǔn)又是從哪里來(lái)的呢？原來(lái)**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(biāo)準(zhǔn)。好了，那么，馬車為什么要用這個(gè)一定的輪距離標(biāo)準(zhǔn)呢？因?yàn)槿绻菚r(shí)候的馬車用任何其他輪距的話，馬車的輪子很快會(huì)在英國(guó)的老路上撞壞的。為什么？因?yàn)檫@些路上的轍跡的寬度為四點(diǎn)八五英尺。這些轍跡又是從何而來(lái)呢？答案是古羅馬人定的，烏魯木齊鐵路重軌價(jià)格，四點(diǎn)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(huì)長(zhǎng)，烏魯木齊鐵路重軌價(jià)格。我們?cè)賳?wèn)：羅馬人為什么用四點(diǎn)八五英尺為戰(zhàn)車的輪距寬度呢？原因很簡(jiǎn)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(shí)上還沒(méi)有完。下次你在電視上看到美國(guó)太空飛船立在發(fā)射臺(tái)上的雄姿時(shí)，你留意看，在它的燃料箱的兩旁有兩個(gè)火箭推進(jìn)器，這些推進(jìn)器是由設(shè)在猶他州的工廠所提供的，烏魯木齊鐵路重軌價(jià)格。如果可能的話，這家工廠的工程師希望把這些推進(jìn)器造得再胖一些，這樣容量就會(huì)大一些，但是他們不可以，為什么？因?yàn)檫@些推進(jìn)器造好后，要用火車從工廠運(yùn)到發(fā)射點(diǎn)，路上要通過(guò)一些隧道。伊犁的重軌廠和田的重軌廠。烏魯木齊鐵路重軌價(jià)格</p><div
