摘要
讨论了化工过程中的时空多尺度效应,小波分析方法在化工过程时空多尺度问题上的应用.仿真结果表明,利用小波对多尺度信号进行重构时有较好效果,并且噪声越小,重构效果越好.但是如何合理地选择小波函数还需要进一步深入研究.
Effect of time-space- mutiscale and its application in the chemical engineering were discussed.Emulational experiments showed that the wavelets had good effect on re-form the multiseale signal, and the less the noise, the more precise the re-tormed signal. But how to choose the proper function of the wavelet still needed to be studied in the later reseach.
