Applying the Large-scale multi-configuration Dirac-Fock wave functions, we calculated the parameters such as wavelength, oscillator strengths and excited energy for the transitions related to lightning spectra. The most important effects of relativity, correlation, and relaxation are included in the computational model. Comparison of the calculated results with experimental spectra shows that the spectra in plateau area have a distinctive characteristic. Beside the lines of lower excited state with n=3 in NII ions, transitions of NI and OI are increased, their excited energy is around 13~14eV, and there are rarely lines from OII ion.

The growth relationship between spectrum parameter and fetch were studied, from which three parameters and overshot phenomenon that appears during wind wave spectra developing were tested, and an equation describing the growth of three-parameter spectra with wind wave was obtained With the equation, the spectra of wind waves were obtained at zero-dimensional fetches of 300, 500, 2000, 5500, 10000, and 15000, and the overshot was described more clearly. However, the overshot does not exist in the whole process of wind wave spectrum development as stated previously by Hasselmann, but in the early stage of the development only, extenuates with wave growth and then disappears when the wave fully grows.

基于已得到的谱参量随风区的变化关系,对三参量风浪频谱以及风浪频谱成长过程中存在的&超射&现象作深入的研究,得到三参量风浪频谱随风区的成长关系:在此基础上,得到无因次风区:300、500、2000、5500、10000、15000下,风浪频谱的谱线,从而直观地描述了风浪频谱成长过程中的&超射&现象,并认为在风浪频谱的成长过程中确实存在着&超射&现象,但是该现象并不如Hasselmann等提出的理论中阐述的那样存在于风浪频谱成长的全过程,而是仅存在于风浪频谱成长的初期。

The results reveal that spectra obtained by different parametric methods are similar. The spectra of normal cells' voltage have only one noticeable lobe due to fluctuation of molten alumina at anodes, while spectra of other abnormal cells have one mainlobe and one sidelobe. In cells with carbon in bath the spectral mainlobe of cell voltage is still due to the fluctuation of molten alumina at anodes and the sidelobe is due to the fluctuation of carbon in bath; in cells with metal pad wave, the spectral mainlobe is due to metal pad waving and the sidelobe is still due to the fluctuation of molten alumina at anodes. Compared with wavelet packet analysis, spectral analysis is simpler and takes less time in calculation, which is a big merit in the large-scale application of online diagnosis systems of working conditions in aluminum reduction cells.
