BP网络在AB_5三元系储氢合金热力学特性研究中的应用

BP Network Method Applied to Thermodynamics Character of AB5-Type Three-Part Hydrogen Absorption Alloys

设计了一个通用ＢＰ程序算法模型，取了若干ＡＢ５三元系储氢合金相的４０℃的Ｐ－Ｃ曲线数据作为训练点，筛选出表征Ｐ－Ｃ关系的有效参数集。对不作训练的“未知”样本的Ｐ－Ｃ关系曲线作计算机预测，并得到多元合金相的热力学特性可用化学键参数和间隙孔洞尺寸来拟合描述。

In this paper,a general BP network method is given at first.BP network has been used to find the regularities of the P-CWTFZ relationships of AB5-type three-part hydrogen absorption alloys.The results of the computerized prediction show the usefulness of this method for the design of hydrogen absorption alloys.And a conclusion is drown that the thermodynamics character of multicomponent alloy phases can be strongly affected by the chemical bond parameter and the hole size.
