从一次测定结果求得重油的粘度范围推导出一个根据一次粘度测定结果，求得未加工沥青和重油的不同温度下的粘度的关联式。用这一关联式对许多油样进行了测试，所得结果与实测值很吻合，如果把参比粘度测定考虑进去则更为准确。预测未加工沥青和重油的温度对绝对粘度的效应...
Based on the determination of the viscosity range of the heavy oil from a measurement result, a correlation of the viscosities of the unprocessed pitch and the heavy oil at different temperatures was derived from the primary viscosity measurement. Many oil samples have been tested using this correlation and the results are in good agreement with the measured values, which is more accurate if the reference viscosity measurement is taken into account. Predict the effect of temperature on the absolute viscosity of raw asphalt and heavy oil ...
