| 摘 要： | 应用相关性分析方法和逐步回归方法分析了柴油的组分和性质与发动机的排放之间的相关性，求得了相应的相关系数和回归方程。计算和实验结果表明，相关系数较在的因子对发动机的排放的影响也较大，使用相关系数较大的因子进行回归分析时，可以得到较高的拟合精度，简化计算过程。

| Abstract: | Correlation analysis and stepwise regression methods were applied to analyze the relationship between compositions and properties and the exhaust emissions from engines. The corresponding correlation coefficients and regression equations were obtained. The evaluated and experimental results showed that the factor with bigger correlation coefficient had bigger effect on the exhaust emissions, and the regression equations by using the factor with bigger correlation coefficient could get a higher simulative accuracy and simplify the calculation process. |
