英文摘要：

The valuing indexes and some main influencing factors in iron ore sintering capabilities were investigated in this paper. Based on the research, a BP neural network learning algorithm with amending error, appending momentum and adaptive variable step size linear reinforcement was presented, and a predictive model of iron ore sintering capabilities was established. By adopting the BP neural network with the 12-34-4 structure and after 6 700 times train, the predictive result of model of iron ore sintering capabilities is satisfying, the neural network training error is 0.000 187, and the predictive hit-ratio of random samples is over 83.5%. It can be concluded that the predictive model is generally applicable and has self-adaptability.
