摘要
依据黏度的经验关联式,选用某石化公司催化原料及其馏分的性质数据,探讨了该馏分黏度与温度关系的数学模型,并利用非线性单纯形法进行回归计算,得到黏度-温度模型的相关经验常数。
On the basis of viscosity empirical correlations, the catalytic material and the nature data of its fractions of a petrochemical company was used to study the mathematical model of viscosity and temperature. The regression ealculation of nonlinear simplex method was used to get the empirical constants of viscosity - temperature model.
