  2. The performance of modulators employing mqw is governed by the quantum confined stark effect. in order to simplify the analysis of mqw, we obtain an explicit formula concerning the correlations between the gaas / gaalas quantum well widths of finite potential barrier structure and those of infinite potential barrier structure under the condition that the ground state energies are equal at zero bias states. then the transfer matrix method is used to investigate the optical field distribution in the mqw waveguide based on five - step asymmetric coupled quantum well structure that is really used in the modulator

    本論文首先根據量子限制stark效應，發展了等效寬度思想，提出了把單量子阱結構的有限深勢阱的分析轉化為無限深勢阱模型的顯式公式，從而大大簡化了電場下量子阱結構的分析；接著利用轉移矩陣，把周期性的量子阱結構簡化為三層結構，得到了實際採用的非對稱三阱結構量子阱的場分佈，並討論了量子阱結構的偏振特性。
  3. Electrochemical syntheses method and hydrothermal syntheses processing are the important two methods of ssp. comparing other methods for preparing functional thin films, these methods have some advantages over conventional thin films processings such as low energy consumption, high yield and one step formation of the thin films etc. so these methods may have great potential to application in this thesis

  4. In order to further investigate the role of axudl in human tumor carcinogenesis and the potential association between the axudl gene expression status and the stimulation of transforming growth factor beta in human cancers, the present study was performed in three aspects as follows : ( 1 ) cloning full length enconding region cdna of axudl and construction of eukaryotic vector that expression the fusion protein of axud1 and influenza virus hemagglutin ha epitope tag ; ( 2 ) exploring the time and dose effects of tgf - 1 on the expression - of axudl gene in hepg2 hepatoma cells and spc - a1 lung carcinomas cells, and studying the effects of overexpression of axud1 on the expression of cell cycle and apoptosis related protein in hepg2 hepatoma cells ; ( 3 ) construction and expression of human axudl in e. coli m15. the following main results and conclusions can be obtained from the present study : 1. the full length ecnoding region of human axudl cdna from human peripheral blood lymphocytes was successfully cloned using one step rt - pcr method, and constructed into a eukaryotic expression vector which can be expressed a ha - axud1 fusion protein with axud1 and influenza virus hemagglutin ha epitope tag. the recombinant plasmid was identified by polymerase chain reaction, restriction endonuclease maping and sequencing, this expression vector might be instrumental to further study the function of axud1 protein in tumor cells
