In this thesis, the resonance fluorescence spectra of a A-type three-level atom is calculated, which is driven by two bichromatic fields having the same difference of the frequency. In addition, the influence of the relative phase difference on the fluorescence spectra are considered. It is found that the fluorescence spectra of the atom are deeply depend on the relative difference and the appearance and cancellation of the fluorescence are obtained by changing the relative phase difference.

First, calculates the fast moving average (usually 12 days) and slow moving average (usually 26 days) by exponential calculation method; second, make fast line value minus slow line value to gain the difference of relative distance. In order to make the trend signals more clear and less influence exerted by of excessive price fluctuation, the difference should be smoothly calculated (general elect 9 days) to get average of difference value. Chart the difference and its average in a coordinate with time for horizontal axis and MACD for vertical axis. Then we can apply the identical, contrary or cross signals through observing their direction, relative and absolute positions.

This project was established based on the first cooperative development of optical in situ real time detecting technique probing the atomic scale layer-by-layer epitaxy growth of oxide film. Over the last three years, we have given full play to the advantages and characteristics of both sides and have finished the assumptions and plans of this subject satisfactorily. 1. In Institute of Physics, we set up advanced oblique-incidence reflectivity difference equipment and wrote one data acquisition procedure that made the simultaneous detection of optical signal and RHEED signal into reality. 2. The first observation of sustained oscillations over hundreds of monolayers in both real and imaginary signals during the epitaxy growth of SrNb0.1Ti0.9O3 on SrTiO3 substrate in LMBE testifies that oblique-incidence is an excellent method to detect and monitor film epitaxy growth real time. 3. For the first time, we verify that oblique-incidence reflectivity difference method can be used to monitor the layer-by-layer growth mode during continuous growth through the correspondence between optical signals to atomic or molecular step edge density on the growth surface. 4. Phenomenological analysis shows that optical signals comprise three parts, the first is proportional to the average thickness of the film and depends on the bulk phase dielectric response; the second is proportional to the coverage of terraces and depends on the dielectric response of atoms or unit cells in the terrace; the third is proportional to the coverage of step edges and depends on the effective dielectric response of atoms or unit cells at step edges. This makes oblique-incident reflectivity difference technique a quantitative macroscopic method to monitor film growth.
