The giant panda-rabbit interspecies reconstructed embryos were constructed by injection of giant panda somatic cells into the perivitelline space of the enucleated oocytes and fused by electrical stimulation, and the reconstructed embryos can develop to hatched blastocyst stage in vitro. We demonstrated that the nuclear genetic materials in reconstructed blastocyst cells were the same as that of giant panda somatic cells by chromosome count and the existence of characteristic chromosome, which was confirmed by microsatellite DNA analysis later In order to determine the fate of mtDNA of giant panda-rabbit reconstructed embryos, we analyzed the cyt b sequence of embryos at 1 -cell stage, 2-cell stage, 4-cell stage, 8 cell stage, morula stage, blastocyst stage, expanded blastocyst stage and hatched blastocyst stage.

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.
