A method for predicting colored noise by introducing prediction of nonlinear timeseries is presented. By adopting three kinds of neural networks prediction models, the colored noiseprediction is studied through changing the filter bandwidth for stochastic noise and the samplingrate for colored noise. The results show that colored noise can be predicted. The prediction errordecreases with the increasing of the sampling rate or the narrowing of the filter bandwidth. If theparameters are selected properly, the prediction precision can meet the requirement of engineeringimplementation. The results offer a new reference way for increasing the ability for detecting weaksignal in signal processing system.

我国南方酸性土壤含锌量一般是比较高的,但是长期施用大量石灰后,pH值就升高,锌与有机质的络合能力也就增强,而锌的有效性却降低,作物就会感到锌的不足。因此,在这时施以锌
