4、力源裝置。本文在傳統(tǒng)的杠桿式力標(biāo)準(zhǔn)機(jī)的基礎(chǔ)上提出了變臂比杠桿式精密力源技術(shù)及其裝置的問題,論述了通過改變和精確控制固定質(zhì)量砝碼沿杠桿臂長方向的位置,達(dá)到準(zhǔn)確施加力值的目的這一力源技術(shù)方法,研究了這種力源的誤差來源與控制、工作效率、經(jīng)濟(jì)成本及結(jié)構(gòu)實現(xiàn)等問題,據(jù)此建立了變臂比杠桿式精密力源技術(shù)理論基礎(chǔ)。關(guān)鍵詞：動力；技術(shù)；杠桿臂長ABSTRACTForceStandardMachinewhichisequippedwithstandardforcesource,canachievethecalibrationofforcemeasuringapparatus.loadcellperfo
