The main work can be summed up as follows: Firstly, we studied the thermal-field properties of VCSELs, and analyzed the influences of current spreading, material parameters and operating conditions on the temperature distributions. Secondly, we began with the electrode voltage and calculated the equipotential s distributions, compared the distributions of voltages and current densities in different depths of VCSELs, and then studied the influences of the oxide-confining region with different position or thickness, and the different sizes of the gain-guided aperture and emitting window on the distributions of the injected current density, carrier concentration and temperature in the active region. Thirdly, we realized the coupling of electricity, optical and thermal-fields, worked out the threshold voltage, calculated the distributions of the injected current density, carrier concentration and temperature under different offset voltages, and analyzed the impacts of temperature profile and carrier density on the refractive index, Fermi levels and optical-field. Finally, we gave the equipotential line distributions with considering N-DBR and double oxidized-confining regions, and analyzed theinfluences of N-DBR and double oxide-confining regions on the distributions of the current density, carrier concentration, temperature and optical-field.

It was found that 0.25%o potassium sorbate produced a positive inhibition against short G+ spore bacillus with a concentration less than 5xl04cfu/ml. A concentration less than %o potassium sorbate hardly exerted a complete control towards short G- plump bacillus having a population density of 5x104cfu/ml. It was proved that use of l% potassium sorbute never controlled the growth of G+ coccus, G~ spirilla and enterobacter with a population density of 104cfu/ml. 1mmol EDTA completely controlled the growth of G+ short spore bacillus and G+ coccus whose cell density was 5xl04cfu/ml. A level of lmmol EDTA showed a limited inhibition against the growth of G- spirilla with a population density of 105 cfu/ml. However, a level of 10mmol EDTA completely controlled the growth of the G- spiral bacteria having a population density of 105cfu/ml. lOmmol EDTA produced a very significant control towards the growth of G"" plump short bacillus with 105cfu/ml. 20mmol EDTA showed a remarkable inhibition against the enterobacter with a population density of 105cfu/ml. Different concentrations of nisin including 25mg/mL, 50mg/mL, 75mg/mL and 100mg/mL were used as bio-preservative to examine its effects against the growth of all strains leading to the spoilage of fresh mutton meat. It was seen that there was a big difference in nisin's concentrations in inhibiting the spoiling bacteria. Generally speaking, as more as 75mg/mL of nisin significantly inhibited the growth of G+ short spore bacillus, G-plump short bacillus, enterobacter, G'spiral bacteria and G+ coccus having a population density of 105cfu/ml.

The discovery of annual density bands of mass coral skeleton had a profound effect on coral paleoclimatology, and many patterns of density bands have been revealed throughout the global tropic ocean since then. At the first stage, people tended to explore the control factors of density changes from the environment where the coral grows, but they did not succeed. Since later part of 1980s, some researchers have focused on the skeletal architecture and integrated the signals of both environment condition and skeleton density bands to reveal the mechanism of skeleton density changes, and finally a model of skeleton growth was developed which can explain the almost existed patterns of skeleton density changes.

The difference of bulk density of coastal soils took an effect on infiltration rate and diffuse rate. The infiltration rate and diffuse rate of coastal soils which bulk density was small were big. The water transmitting experiment of coastal soils showed that the saturated conductivity of different layers in soil profile were great, and the saturated conductivity of undisturbed soil was highly higher than that of disturbed soil. The saturated conductivity of coastal soils embanked earlier was lower than that of coastal soils embanked later. Under different water content, the unsaturated conductivity of coastal soils had a great change and the bulk density had an effect on unsaturated conductivity. The soil with a low bulk density had a high unsaturated conductivity. Chlorine ion moved in coastal soil was an inert ion. The distribution of CU in soil was definite and repeated, which is no relation with the time and velocity of infiltration. The concentration of infiltration solution and the texture of coastal soils had no apparent effect on solute movement synthetic dispersion coefficient, while bulk density took an apparent effect on solute movement synthetic dispersion coefficient. Synthetic dispersion coefficient of coastal soils increased as bulk density decreased.
