HCFCs和HFCs对流层寿命的预测

PREDICTION OF TROPOSPHERIC LIFETIMES OF HYDROCHLOROFLUOROCARBONS AND HYDROFLUOROCARBONS

利用Ｃ—Ｈ键的Ｍｕｌｉｋｏｎ键重叠布局数，对甲烷的不完全氟氯取代物的对流层寿命用公式作了计算．对传统的人工神经网络法（ＡＮＮ）－反向传递算法（ＢＰ）作了改进．在电荷数这一量化参数基础上，用ＡＮＮ法对一碳和二碳的ＨＣＦＣｓ和ＨＦＣｓ的对流层寿命作了预测．

Based on Mullikon bond overlap populations of C—H, the tropospheric lifetimes of one carbon HCFCs and HFCs were calculated. The back propagation algorithm used in artificial neural network has been improved. On the basis of gross charges of carbon atoms in F, Cl substituted methyls, the tropospheric lifetimes of one and two carbon hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs) were predicted.
