A detailed model of non-linear parametric excitation vibration coupling the stay cable and the girder, in which the static sag as well as the geometric non-linearity are considered, is proposed in this paper. Based on several numeric examples investigated by the Galerkin method composed with the integration strategy, several kinds of factors effecting stay cable parameter vibration are studied. Another parameter vibration model by the axial excitation is presented and the corresponding nonlinear equations are derived. The smallest excitation amplitude,the transient state and steady state resonance amplitudes, and the changing characteristics of the axial force are obtained by using harmonic balance method. According to numerical examples calculated by numerical integration method, the effects of the inner damping of the stay cables are investigated.

The hyperfine effects emerging in all spectra of atomic Rydberg states are due to the nuclear effects including hyperfine structure and isotope shifts. The autoionizing Rydberg states converging to 6p〓 and 4f〓 5d6s 〓 [3/2] 〓 limits were investigated by three photon excitation.
