By using Lee\'s matching law, the excess pore-air pressure, excess pore-water pressure and settlement in the Laplace-transformed domain are obtained for one-dimensional consolidation in unsaturated soils, under the large-area uniform instantaneous loading. A computer program using the method by Crump and Durbin is developed to obtain the semi-analytical solution of the excess pore-air pressure, excess pore-water pressure and settlement under the boundary conditions of the top surface permeable to water and air and the bottom impermeable to water and air.

The thesis can be divided into five parts as follows: First, the structural characteristics of finned-pipe evaporator are analyzed. After selecting suitable microelement controller, the heat-transfer and mass-transfer processes are analyzed for every microelement under the conditions of dryness, wetness and frostiness. Based on previous equations, some parameters of frostiness are confirmed and the frost-growing model is set up under frost condition. Some hypotheses are postulated and with the help of the equation of mass-conservation, energy-conservation and momentum-conservation, the evaporation model which fits in the dynamic simulation is built, which set a solid foundation for system simulation. Second, the starting and stopping behaviors under disturbed condition are analyzed and calculated by using the dynamic concentrative parameter model, which gives some advice to better prescribe refrigeration system and set theoretic foundation for carrying out automatic control of refrigeration system. Third, the normal running process is analyzed and calculated by means of rational matching theory, which gives some advice on how to better understand the parameter change under steady state and the affection of inlet-parameter on evaporator. Fourth, the simulation software with dynamic characteristic is designed, which can be applied to calculate thernio-parameter of cryogen, air humidity and frost thickness under different initial and boundary conditions, and to carry out dynamic simulation under conditions of dryness, wetness and frostiness, at the same time, to achieve detection and simulation at any stage from starting to stopping.

Because the EPWE method is designed to derive easily the evanescent modes which can be used for the matching boundary conditions, we can get the transmittance for the semi-infinite photonic crystal. In this study, some interesting behaviors can be observed, for example, the transmittance is very sensitive to the surface we chose. The transmittance even can be almost 1 or 0 when the cutting planes of photonic crystal are different for the specific frequency. In this proposal I want to see the reason of the total reflection which seems to be conflicted with the existence of the propagation modes at that frequency and what will be happened when we consider the finite thickness case.
在EPWE 的方面,在这三年的时间里,我会尽量完成有限厚度的光子晶体的计算,因为以前主要算的是半无穷的光子晶体的计算,当中也看到了一些很有趣的行为,比方某些频率下,其穿透率与它的介面有很大的关系,因为,当光子晶体的切面不同,在特定频率下,其穿透率可以由几乎全穿透变成全反射,这里我想看看如果考虑厚度,到底会对系统有什麼影响。
