To put up founding and test experiments in these two ways separately, the first model use fixed training data to train the network and it constringed at the ninety circles, it's test identifying rate is eighty eight percent;the second model use the same fixed training data to train the network and it constringed at the sixty circles, it's test identifying rate is ninety nine percento Thus shows that the model with the switched character data is more better in identifying rate and it' s training time is shorter than the model used the character data directly,, Use BP Neural Network to forecast the Medicine Production quality is a better method..
