| 摘要: |
| 采用回归分析方法对双燃料发动机速度特性试验结果进行分析，建立了功率、扭矩与转速间的数学模型，模型决定系数(R2)均达到0.99以上。并对模型进行了数学分析，获得了功率和扭矩的变化速率、最大功率及其置信区问、扭矩的拐点及最速下降区问等结果。最后通过实例分析讨论了模型的应用。 |

| Abstract: |
| The regression analysis method was adopted to build mathematical models about the power and torque relative to rotation speed of daul-fuel engine based on velocity characteristic test results.The decisive coefficients of these models exceeded 0.99.Some technical parameters such as the variational rate of power and torque,the highest power and its confidence interval,the inflection point and its fastest descent zone of the torque were resulted from the analysis on the models.Finally,the applications of these models were put forward through case study. |
