This thesis introduces the research history of sonoluminescence, the properties and equipments of single-bubble sonoluminescence and the factors affecting the amount of light emission. Based on the experimental realization of SBSL, the experiment in this thesis is to confirm the coherence between the emitting frequency and the driving cycle of SL. Under this feature ,we established the programme of the experiment that measure the angular correlations in SBSL , built the experimental devices and conducted initial measurements .Then we got the conclusion that there is a presence of non-spherical symmetry in the process of SBSL .

With the combination of lighting, cooling and heating under daylighting, the study on the effect of the key characteristic parameters on total energy consumption is provided. The validation of the comparability of daylight distribution for building antetype and model is made through theoretical analysis and simulating calculation in the thesis. Due to the variable sky condition, daylighting factor is used for experimental validation instead of illuminance. The error analysis of several testing methods used in the experiment is conducted, followed by the experimental validation of the effect of WWR, sill and transmittance on daylighting factor distribution.

The works in the project just done can be summarized as five respects.(1) A device was designed to fabricate the asymmetrical resonant cavities by a pendant drop. A series ARCs with variable parameters provides a valuable experimental method for investigating the characteristics of ARCs.(2) The relationship between the number of active modes and the shape parameters in an ARC was investigated. The experimental lasing threshold was compared with theoretical result, the good agreement between two shown that it was the decrease of the number of active modes in an ARC that decreased lasing threshold.(3) Dye lasing gain was used to enhance the signals of stimulated Raman scattering of the weak gain Raman modes in a circular cavity made by a pendant drop, the instantaneous SRS spectra of weak gain Raman modes in ethanol was obtained by this new method.(4) The SRS signals of minority compound in a binary chemical complex was obtained by using dye lasing gain method. The detection concentration of minority compound was reduced to an order compared with normal SRS method.(5) A cylindrical circular cavity was formed by a liquid jet, which was used to reduce the pump intensity required for laser induced plasma spectroscopy. The limit of detection of trace element in aqueous sample was greatly decreased by this new method.
