摘　　要：ＢＰ网络的目标点附近收敛速度较慢，学习效率较低，解释复杂，常不能保证全局收敛而导致学习失败。通过对其算法进行改进，并应用改进后的ＢＰ神经网络对红桔振动损伤进行分析建模，能准确地反应其损伤程度。BP network is a kind of very useful nervous network. However, there are some problems about it: (1) the converging speed at the target spot is very slow, which lowers the efficiency of study; (2) when used to explain some relatively complicated problems, it can't always conuerge completely, which may lead to failure in study. We manage to make improvement on it and supply an actual application of the improved BP network.
