| Abstract: | Using first time approximation, the gradually stability and topology structure of the equivalent system for two kinds of degree three return circuit equation with sine, cosine phase obtained via ideal separator of integral and separator of RC integral, and for a kind of degree three return circuit equation with tangent phase obtained via separator of RC integral was worked out in this paper. The attraction field for the gradually stability of equilibrium points was explored via the second method of Liapunov, the theorical basis for the unlockage of the return circuit equation was offered. |
