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.

光谱沿轴向、径向均出现蓝移或红移，随着相对传输距离、光阑截断参数、空间相干参数及折射率结构常数的增大，脉冲时间相干长度的减小，轴向光谱蓝移量或红移量逐渐增大，并且由明显地起伏逐渐趋于稳定，沿径向出现了光谱开关，光阑截断参数、脉冲时间相干长度、空间相干参数和折射率结构常数对光谱开关的数目、光谱开关的临界位置和光谱跃迁量等也产生影响。

The theory and application is explained in this paper. Software XMGREDIT5 matching ELCIRC is used to generate unstructured grid, and is considered fit for ocean but rivers. Tidal current is simulated and validated well, and sensitivity of current structure to bathymetry is visible. Affection of wind is qualitatively analyzed here. At the same time the model is improved on as required, like the tidal open boundary which could choose not only long period harmonic constant but also short period harmonic constant and tidal level, and multi-point results and flow field data could be exported effectively with binary results.
