The nanocomposites have been characterized by four - point probe conductivity measurements, uv - vis, transmission electron micrograph. the results show that polyaniline / tio2 has higher conductivity ( xl0 compared with that " of eb, the uv - vis spectra properties of polyaniline / ti02 depend on the ratio of tio2 to polyaniline. the uv - vis spectra of nanocomposites doped with hcsa take place red - shift and possess higher conductivity and better solubility compared with those of nanocomposites and pani
並對樟腦磺酸摻雜聚苯胺（ csa - pani ）的性能，及其在不同的有機溶劑中的紫外-可見吸收光譜進行了詳細的探索，本文還對csa - pani成膜進行了探索，結果表明： csa - pani在間甲酚中具有最好的溶解性，並能保持基本的穩定，是成膜的理想體系。 -
A new e. coli promoter - probe vector phn1005 was constructed by using a red - shift enhanced gfpmut3 as reporter gene and showed the following characters : 1, bamhi at the 5 " end of gfpmut3 structure gene could be used to clone promoter - active fragment and the strength of promoter could be quantitatively assayed. 2, a rrnbtlt2 terminator from rrna gene at the 3 " end of gfpmut3 could permit clone strong promoter. 3, another rrnbt1t2 terminator was inserted upstream bamhi to prevent reading through of promoters from puc19
進一步以紅移且熒光強度提高21倍的gfpmut3為報告基因，構建了大腸桿菌啟動子探針載體phn1005 ，該載體上gfpmut3結構基因5 』端的bamhi位點可用來克隆具有啟動子活性的dna片段並定量分析插入的啟動子強度；其3 』端含rrnat1t2終止子，可允許克隆強啟動子；在bamhi上游同樣插入rrnat1t2終止子以防止載體puc19上的啟動子的轉錄通讀； gfpmut3結構基因上游還插入一段內含子序列使正反六種讀碼框的翻譯均可被終止，可保證gfpmut3以正確的讀碼框翻譯。 -
Secondly, basing on the theory of on - off gain of small signal, the raman gain coefficient for frequency shift between 0. 5 and 20 thz of standard sigle mode optical fiber is measured by pump - probe method through a super luminescent diode ( sld ) as a broadband small signal probe source. thirdly, numerical simulation analysis of gain characteristic of raman fiber amplifier for c band wdm signal light is made according to the raman gain coefficient of the fiber measured before through target and four rank runge - kutta method. at the invariability of wavelength and maximum power of each of two pumps, schematic of powers of two pumps for best flatness on c band wdm optical gain was found out, at the same time, the factors of resulting in gain saturation is analyzed, too
本文首先應用經典的電磁理論對拉曼光纖放大器的工作機制進行了分析，然後，根據小信號理論推導出的開關增益求出了光纖拉曼增益系數的表達式，採用泵浦-探測波的方法，利用超輻射激光二極體（ superluminescentdiode簡稱sld ）作為探測光源，測量了所用標準單模光纖頻移為0 . 5 - 20thz的拉曼增益系數，之後根據所測得的光纖的拉曼增益系數譜對應用該類光纖構成的放大c波段wdm光信號的拉曼光纖放大器的增益特性採用打靶法和四階龍格- - -庫塔進行了數值計算，在給定了兩個泵浦光源的波長和最大功率后，找出了反向泵浦情況下使c波段wdm光源增益最平坦的兩個泵浦的各自最佳功率，同時也分析了導致信號光飽和的原因。 -
As an example, we studied the co - propagation of two soliton beams with one ' s amplitude is much stronger than another. it is then found that the weaker ( probe beam ) can experience a very large phase shift within a rather short propagation distance by modulating the input power of the stronger ( pump beam ). chapter 3, nnlse is simulated for two beams propagation
