When the TN:TP ratio was 25:1,V.spiralis had the best growth, with a biomass increment being 54% and 31% higher than that when the TN: TP ratio was 12.5:1 and 50:1, respectively, while the growth of periphyton, especially of epiphytic algae, was the worst, giving the least adverse effects on V. spiralis, indicating that a 25:1 of TN:TP ratio in eutrophic water was optimal for the growth of V. spiralis. However, such an optimal TN: TP ratio only worked when the nutrients concentration in eutrophic water was below the limited level, otherwise, it could be failed to be applicable.

Based on this, aim at the disadvantage on Wigner Distribution and Fractional Fourier Transform that can't restrain noise interference effectively when be used to detect Linear Frequency Modulated signals interfered by heavy noises, we proposed a improved WD. Simulation results show that this method can restrain noise interference effectively and improve the ability of LFM signals detection. On the other hand, in multi-component cases, WD suffers from the cross-terms, which may impair some of the auto-terms. In order to separate original multi-component signals into components and reconstruct them separately, we can use the method of optimal filtering in fractional Fourier domain. But this method also has a problem that if signals have aliasing in the fractional Fourier optimal domain as well, the reconstructed signals will be distorted. In this thesis, a novel method of quasi Fourier transform is proposed in order to solve the problem of multi-component signal reconstruction, and have good results.
