free acid gas
解釋
游離酸性氣體-
The corrosion behavior of nanocrystalline ( nc ) copper bulks with various grain sizes prepared from igc ( inert gas condemsation ) and vacuum annealing in comparison with conventional microcrystalline ( mc ) copper ( as - rolled and electrolytic ) in acid copper sulphate solution and neutral solution containing chlorides under free corrosion conditions and anodic polarizations has been studied using potentiodynamic polarization, potentiometric analysis, cyclic voltammetry and electrochemical impedance spectroscopy. x - ray diffraction was used to estimate the grain size of the annealed nc copper. field emission gun scanning electron microscopy and x - ray energy - dispersive spectroscopy was used to characterize the surface morphology and analyze the surface composition after the polarization and potentiometric test of both nc and mc copper
本文研究了用igc （惰性氣體蒸發凝聚原位溫壓法）制備並真空退火到不同晶粒尺寸的納米晶銅和微米晶銅（冷軋紫銅、電解銅）在酸性硫酸銅溶液和中性含氯溶液中，在自腐蝕狀態和陽極極化狀態下的腐蝕性能。使用了動電勢極化、電位測定、循環伏安法（ cv ）和電化學阻抗譜（ eis ）等方法。 x -射線衍射（ xrd ）的方法用來估算納米晶銅晶粒尺寸。 -
It can not only remove gas, water and impurity, but also free carbon, decolor, deacidify, medium loss reducing and resume utilization property of oil to achieve treated oil up to national standard on water content, gas content, ph number and acid number, ect
它不僅能脫氣脫水除雜質，而且還具有去除絕緣油中的游離碳脫色除酸降介損的功能，恢復油的使用性能使處理后油中的含水量含氣量ph值酸值等均符合國家標準。 -
It can remove water content, gas, impurity in oil as well as polar material in degraded oil, reduce acid number, medium loss number, remove free carbon and enhance withstand voltage and quality to guarantee operation of electric equipment
可作為電力變壓器大修專用過濾設備，不但能高效去除油中的水分氣體雜質，而且能快速除去老化變質油中的極性物質，降低油液酸值，介損值，除去游離碳，提高油的耐壓強度和油的質量，確保電力設備正常運行。
