摘　　要：通过测定50℃时L-TSA 32及L-TSA 46号矿物涡轮机油中溶解气体奥斯特瓦尔德系数(Ostwald系数),经与50℃国产矿物绝缘油中气体Ostwald系数对比及拟合后,发现两者线性相关,给出了利用气相色谱法检测矿物涡轮机油含气量的校正公式及简易换算方法,可为矿物涡轮机油含气量及油中各气体组分含量的检测提供指导。The Ostwald coefficients of dissolved gases in L-TSA 32 and L-TSA 46 mineral turbine oil at 50℃ were detected,and then compared with the Ostwald coefficients of the domestic mineral insulating oil.After fitting these data it finds that they are linearly dependent.The calibration formula and simple conversion method for gas contents of mineral turbine oil by gas chromatography are presented,which provides guidance on content determination for each component in mineral turbine oil.
