Research Interests

1991-1996, had researched macroscopic properties of Nuclei with extended Thomas-Fermi(ETF)model. 1996,Began to study the problem of disposal of long-live, highly radioactive waste of nuclear reactor, and the possibility of the accelerator driven nuclear reactor, and the scattering problem between intense laser beam and electrons. 1998, have begun the theoretical and experimental research of the problem of single bubble sonoluminescence. The partial differential equations of fluid mechanics are employed to numerically calculate the process of gas dynamics inside the bubble, the liquid pressure outside the bubble and the bubble instabilities. Develop various bubble-gleaming apparatus, investigate the extreme condition inside the bubble by measuring spectra. This subject includes acoustics and the other physics.
