摘　　要：通过变温粘滞系数实验仪测量一定温度下液体的粘滞系数,研究其随温度变化的规律.利用Origin软件对所得的数据进行非线性拟合,得到了二甲基硅油的粘温曲线和粘温系数.We measure the viscosity coefficient of dimethyl silicone oil in different temperatures by the experiment equipment in order to research the variation of viscosity with temperature. The obtained experimental data are solved by origin. We get the curve and the variation of viscosity with temperature by non - linear curve fit.
