    以氬氣作為推進劑，在不同工況下進行點火實驗，測量獲得了其工作推力、電弧電壓和電流、推進劑流率和弧室壓力等宏觀參數，得到了不同實驗條件下其工作的實際比沖、推力效率、推力/功率比以及比功率等性能參數，分析了推進劑質量流率、電弧功率、電弧加熱發動機電弧室結構尺寸等因素對其性能的影響，為數值模擬研究和實際的低功率電弧加熱發動機優化設計及研製提供了實驗基礎。
  4. It compares and analyses the equipment test voltage emendated to standard atmosphere conditions with the equipment nominal withstanding voltage. and then it concluded that : the emendation value educed by " humidity ratio " integrated emendation method is basically equal or close to the equipment nominal withstanding voltage ; but the values by two traditional emendation methods are mostly higher. it also proves that, " humidity ratio " integrated emendation method is more perfect than any other methods, and it can reflect the influence degree of atmospheric parameters on electrical equipment outer insulation discharge voltage actually

    文中選擇「比濕」綜合校正法和兩種傳統校正法，分別對西高所為羊八井、拉薩、羊湖110kv變電所設備所做的人工氣候室模擬試驗數據及雲南中試所做的zs - 110工頻放電電壓試驗數據進行校正計算，將試驗電壓的校正值與試驗設備的標稱耐受電壓水平進行比較分析；認為： 「比濕」綜合校正法的校正值與設備耐受電壓水平基本相等或接近，而兩傳統校正法的校正值大多高於設備耐受電壓水平；進一步證明， 「比濕」綜合校正法是目前諸多校正法中較為完善的，能真實地反映大氣參數對電氣設備外絕緣放電電壓的影響程度的校正法，在高海拔電力工程設計中應推廣應用。
