semi-classical
1.The Coleman-De Luccia semi-classical vacuum decay theory with gravity is reviewed.
2.A SEMI-CLASSICAL ANALYSIS ON THE REACTION ~(12)C+~(209)Bi AT BOMBARDING ENERGIES SLIGHTLY ABOVE THE COULOMB BARRIER
3.Hawking radiation is viewed as a tunneling process across the event horizon and the tunneling probability is calculated. According to the tunneling probability,a leading correction to the semi-classical emission rate is found.
5.Calculations with a semi-classical model showed that PEE is more convenient than the pulsed field emission in generating stable short-pulse and high bri-ghtness electron beams, and has higher yield than normal photocmission.
6.Two theoretical models were built to describe atom lens. Spherical aberration, chromatic aberration and the aberration caused by angular spread were analyzed with semi-classical model, and diffractive aberration was analyzed using quantum model.
7.Based on the semi classical theory and Maxwell Bloch equations, the amplification of the seed pulse in the laser regenerative and multi pass amplifiers is analyzed. The analytical expression of the peak fluence is obtained by assuming some actual physical conditions. A relationship between the enhancement and stability of the peak output and the gain, loss of the amplifier is discussed in detail.
8.On the basis of the Skyrme interaction, the nuclear matter approach and the self-consistent semi-classical (SCSC) approach, the self-consistent study of microscopic optical potential (MOP) is generalized to the intermediate energy region (60-300MeV). The radial shape and the temperature effect of n + 90Zr optical potential are studied.
9.(2) The semi-active control systems based on MRF-04K damper were further investigated, and the semi-active control law based on the Instantaneous Optimal Control (IOC), the Classical Linear Optimal Control (COC), and the Linear-Quadratic Gaussian (LQG) (only required the acceleration responses of structure as the feedback) algorithms was proposed.
10.In this thesis, a kind of MR damper designed and manufactured recently,named as MRF-04K damper, and three control algorithms, includingInstantaneous Optimal Control (IOC), Classical Optimal Control (COC) andLinear Quadratic Gauss Control (LQG), are introduced. The semi-active controlsystem based on MRF-04K damper is designed, and the semi-active control lawand control effect are defined.
