電車軌標(biāo)準(zhǔn)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(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呢？答案是古羅馬人定的，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。我們再問：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)上還沒有完。下次你在電視上看到美國太空飛船立在發(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。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)，路上要通過一些隧道。新疆輕軌廠家阿克蘇的輕軌多少錢。</p><div

西洋報(bào)刊曾在1901年評論道：“漢陽鐵廠之崛起于中國，大有振衣千仞、一覽眾山之勢。”至于鋼軌的質(zhì)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(chǎn)鋼軌約2萬噸，是中國近代鐵路建設(shè)中***的國內(nèi)鋼材供應(yīng)商，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(jù)估算，至1922年年底，漢陽鐵廠鋼軌所鋪設(shè)的鐵路占中國已建鐵路里程的1/3。1924年，漢陽鐵廠在經(jīng)過了短暫的黃金期后，終因財(cái)政困難、外債沉重而全部停產(chǎn)。*****時(shí)期，**將鐵廠設(shè)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(qiáng)求富”希望的中國近代***鋼鐵廠終究無法擺脫悲劇命運(yùn)，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(shí)際使用過，但是“1902”的年代信息是確鑿無疑的，至今為止國內(nèi)還沒有發(fā)現(xiàn)過幸存的生產(chǎn)年代比它更早的國產(chǎn)鋼軌。甘肅的輕軌廠青海的輕軌廠。</p><div
