One is that system itself is plicated .Other is that in general we gather the chaotic time series of some states of systems only by some “observors” .Hence ,we need techniques which can be used to “recover” the global behavior of systems by the one dimensional projection of the global behavior of systems. This paper will introduce the recent work of the authors in realizing these key techniques.Keywords Nonlinear Chaotic timeseries Fractal,space reconstruction Chaotic model Parameter identification Prediction techonogly
