Abstract: Based on Davydov's bisoliton theory on high-superconductors and a complex transformation, we prove that the displacement in the above theory satisfies the φ4 field form at low excitation approximation. The critical temperature is studied by the soliton statistics method at high-temperature approximation. The fact that the theoretical values approach the experimental values in superconductors YBa2Ou3O7-δ and La1-δSr0.2CuO4 supports the Davydov theory.
Key words: the critical temperature of superconductor, Davydov model, bisoliton
