摘要
依据粘度的经验关联式,选取某石化公司催化原料及其馏分的性质数据,探讨研究了密度对于粘度的影响,并利用非线形单纯形法进行回归计算,由此得到具体的粘度经验式。
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-temperature and density.The regression calculation of nonlinear simplex method was used to get the empirical formula of viscosity.
