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(jīng)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(chǎn)就面臨一個比較大的實際問題——資金不足。清**所撥費用已全部用完，而投產(chǎn)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(chǎn)。

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。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(jié)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。山西的起重軌低價資料。烏魯木齊Qu80起重軌哪家好</p><p
