摘　　要：对文献[1]中公布的辽河油区7组粘-温数据进行了回归分析,并与文献[1]的结果进行了对比,发现文献[1]中给出的回归系数计算有误差。对回归系数进行了误差分析,指出回归系数对粘度计算精度有很大影响。对文献[1]中“通用方程“的叫法提出了质疑,指出称为经验公式比较合适。The regression analysis of seven groups of viscosity-temperature data from Liaohe oilfield published in Ref. [1] of this paper is made, and the results are compared with those from Ref. [1]. It is found that the regression coefficient calculation from Ref. [1] is in error. The error analysis indicates great effect of the regression coefficient on the precise of viscosity calculation. In addition, the denomination of universal equation given in Ref. [1] is oppugned, and it is better regarded as the empirical equation.
