As we have borrowed the wisdom from biological neural network,the characteristic of interference-proof in information transferring process has been carefully studied. Our study includes the response of electrical-interference-proof circuit in electromagnetic environment,by means of bionics redesign. In this way, new principles,new technics and new ways are adopted to solve the unavoidable situations in traditional electro-magnet protection design. Based on the Boolean model,the complex bionic topological networks were firstly built and the charactoristics of degeneracy were analyzed,then the bidirectional actions between degeneracy in networks and the robustness of functions were proved in order to fill up the gap to deal with the need of interference-proof. Based on the creation of the neuron networks and the electrical synapses ’ charac-teristic of plasticity ,the impact of the distribution in the weight of synapse on the character of network self-recovery was studied afterwards so that the corresponding mechanism could be defined.
