| 中文摘要: |
| 通过对一种胎面胶三段混炼过程参数统计分析，指出塑炼段和第2 段混炼过程对混炼胶焦烧性能影响较大，混炼能量消耗与焦烧的相关因数比与时间、温度和功率的都大，而温度与焦烧的相关因数有正有负，影响比较复杂。分别使用三段混炼过程全部参数、塑炼段和第3段混炼的参数和只用第3段混炼的参数回归建立预测焦烧的数学模型，复相关因数分别为0. 941 ，0. 835 和0. 814 ，预测平均相对偏差分别为12. 9 % ，9. 94 %和12. 95 % ，使预测和控制焦烧性能成为可能。 |
| 英文摘要: |
| Based on the statistical analysis of the parameters in a 32stage mixing of tread compound ，it was found that the plastizing stage and the second mixing stage had greater influence on the mixture scorchiness ； the correlation coefficient of energy consumption to scorchiness was
greater than those of time ，temperature and power ；the influence of temperature on scorchiness was more complex ， and their correlation coefficient might be plus or minus. The three mathematic models to predict mixture scorchiness were established by regressing the parameters respectively from 3 mixing stages ，the plasticizing stage and the 3rd mixing stage ，or only the 3rd stage. The correlation coefficients were respectively 01941 ， 01835 and 01814 ， and the predictive average relative errors were 1219 % ，9194 % and 12195 % . These models were used to predict and control the mixture scorchiness. |
