采用高低温运动粘度测定仪测量 PAO8（8＃聚烯烃）合成基础油和45＃变压器油基础油按不同比例调和后混合基础油的粘温性能，运用 Arrhenius模型和 Grunberg-Nissan模型计算混合基础油的理论粘度，研究粘度偏差率随测试温度的变化规律。实验结果表明：Arrhenius模型能准确预测混合基础油的高温运动粘度，粘度偏差率最大值不超过1％，而 Grunberg-Nissan模型能精确计算混合基础油的低温运动粘度；PAO8和45＃变压器油基础油调和能够获得高低温粘度的匹配。

The viscosity-temperature performance of the blen d oils is investigated by measuring the kinematic viscosity of PAO8 (No.8 polyαolefin)synthetic base oil,base oil for No.45 transform-er oil and their blend oils with different blending ratio in the temperature range from 100 ℃ to-30 ℃.The theoretical kinematic viscosity is calculated using Arrhenius model and Grunberg-Nissan model.And the law of viscosity deviation ratio vs.temperature is studied.The experimen-tal results show that the high temperature viscosity can be well predicted by the Arrhenius mod-el.The maximum viscosity deviation ratio is less than 1%.The model put forward by Grunberg and Nissan is more suitable for the calculation of the low temperature viscosity.The blend of PAO8 and base oil for No.45 transformer oil can achieve the high-low temperature viscosity.
