【Abstract】 Basic principle of the infrared measuring temperature demarcating method and the BP neural network is introduced.The back Demarcating method of neural network is described in detail.The application of Demarcating method neural network in fitting the curves of physical experiments is studied.Through training and simulating under MATLAB,the advantage of using BP algorithm neural network in physical curve fitting is proven.And its precision is by far higher than the minimum double multiplication fitting so as to offer a new method to deal with the temperature demarcating software.更多还原
