In order to increase the local searching ability of simulated annealing algorithm,the simplex method and Powell method are introduced.They become the global hybrid inversion method based on simulated annealing algorithm.The combination methods of serializer for SA and Powell algorithms and incrustation for SA and simplex algorithms are given in this paper,and their combined steps elaborated for easy programme.After inverting the modeling and observing curves of direct current induced polarization sounding,the results are very good for the induced polarization sounding curves without equivalent phenomenon.The relative error of model parameters is elementally controlled within 1%.For the induced polarization sounding including seriously equivalent phenomenon and data noise,the global hybrid inversion method can not completely overcome multi-solution,but pvesents reasonable solution estimation by changing model parameter space and algorithm parameters.
