Through analyzing expansion models of gradient based method and phase based method, a content based signal expansion model was presented, in which the signal’s spectrum is shifted to make its character frequency located at zero frequency, then the signal is expanded by Taylor formula, so the drawbacks of gradient based method and phase based method are avoided.

By applying the corresponding parameters of equilibrium manifold expansion model expressed as the spline functions,the identification problems of the relationship between dynamic and static parameters in zone and the continue conditional construction of interzone parameters were solved.
