| 摘 要： | 用路径数2(P2),路径数3(P3),沸点(Tb)与C2~C20的烃类化合物(包括烷烃和烯烃)的闪点(Tf)进行相关分析,发现Tf与上述参数之间存在着良好的相关性,其关系式可表示为:Tf=0.671Tb-0.193P2 1.203P3 17.195.训练组的平均相对误差为1.29%,测试组的平均相对误差为1.79%.该模型的原理简单,方法实用,结果可靠,其预测值与实验值吻合良好,且置信度高达99.9%.

| Abstract: | Through the study on the relation between number of path 2(P2),number of path 3(P3),boiling point(Tb) and flash points(Tf) of 77 alkanes and alkenes(with 2~20 carbon atoms),it is found that P2,P3 and Tb have high correlativity with Tf,the equation can be expressed as follows: Tf=0.671Tb-0.193P2 1.203P3 17.195.The average relative corror is 1.29% for the training set and 1.79% for the test set.The results show that the model has advantage of simple principle,practical method,stable results,and confidence degree high to 99.9%. |
