摘要：介绍采用小波变换的方法实现对信号的消噪 ,且与BP神经网络相结合应用于丙烯腈转化率软测量中。
The implementation of noise elimination of signal by using wavelet transform is introduced. Combining with the neural network it is used in soft measurement of transform ratio of acrylonitrile. The experiment shows that the noise elimination of signal based on wavelet transform is getting more effectiveness than the conventional noise elimination method.
