| 中文摘要: |
| 基于Wiener指数建立调和拓扑指数H,并用H、路径数P2与链烷烃的偏心因子ω进行关联,其二元线性相关系数为0.9986,计算值与实验值很好吻合,平均误差仅为0.0025。所建模型相关性高、稳定性好、预测能力强。 |
| 英文摘要: |
| Based on the Wiener index,a harmonic topological index H is proposed.Furthermore,a quantitative relationship model between the eccentric factor ω and H,path number P2 of chain alkane is established by the multiple linear regression method.The correlation coefficient is 0.9986.The absolute average deviation between calculated values and experimental data is 0.0025 for 51 chain alkenes,and the estimated results are all better than the relevant achievements of literatures.The model has a high correlativity,fine stability and precise predictability. |
