热效率计算软件中BP神经网和扩展节点表的应用

Neural Network and Extended Node Table Applied to Computing Software for Boiler Thermal Efficiency

在工业锅炉热效率计算软件编制过程中,用BP神经网为需要查表的参数建立计算模型,实现自动查表功能;在处理软件中涉及的大量公式的计算顺序问题上,引入扩展节点表的设计方法,大大节省了以往人工计算时间,提高了软件设计的效率。

I n the programming of computing software for industrial boiler thermal efficiency, BP neural network is ap-plied to modeling for tables and automatic query is rea lized.For the problem of how to deal with the order of ex-pressions when desig ning this software,method of extended node table is introduced,owing to which time is greatly economized and efficiency improved.
