本文依据由HMO理论导出的临界温度预报函数,从链状H-[-CH2-]n-OH和H-[-CH2-]n-(◇)同系物不确定度各异的27组临界温度文献值中甄选出一致性样本,据此拟合出临界温度预报函数中的三参数值,得到最大预报偏差分别为0.48 K、0.62 K,平均绝对误差分别为0.29 K、0.45 K,且显著优于复合基团贡献法估算精度的效果.

In this paper, based on the critical temperature predicted function educed by HMO theory, the consistency specimen were selected from homologous compound chain H-[-CH_2-]_n-OH and H-[-CH_2-]_n-?in 27-group uncertain critical temperature literatures. Thereafter three parameters in the critical temperature predicted function were chosen,and the maximum of the predicted error 0.48K, 0.62 K, and the maximum average absolute error 0.29 K, 0.45 K were obtamed.It is much better than the complex group contributi...
