摘要
润滑油的粘度是润滑油的一个重要性能指标,它随着温度变化而变化.本文通过对拉延油的粘度进行测定,然后采用回归分析,得到了非常显著的非线性回归方程.该方程显示拉延油的运动粘度与温度呈高度显著的指数关系.
The viscosity of lubricating oil is a very important performance parameter, it changes with the temperature. The drawing oil's viscosities at different temperatures were tested in this paper. By the regression analysis method, the very evidently equation was given about the viscosity and the temperature. The equation reveals that there lies in an exponential relationship between the viscosity and the temperature.
