The axial direction and radial direction spectrum is blue-shift or red-shift. On axial direction, the blue-shift or red-shift increases with the relative propagation distance, truncation parameter, refractive index constant increases and temporal coherence length decreases, and the spectral-shift gurgitation becom gragually steady. On radial direction, spectral switches appear, and the truncation parameter, spatial coherence parameter, temporal coherence length and refractive index constant also influence critical position and transition height et al.
