  2. This expression vector plbcas - hsa - lgl has the following advantages : i ) the 1. 7kb promoter is able to drive cell - specific and hormone - dependent expression ; ii ) the inclusion of intron - 1 can increase expression level of fusion genes ; iii ) the 5 ' utr of bovine p - casein mrna may have a positive role in both transcriptional and post - transcriptional regulation ; iv ) the gfp gene make the selection of positive clone among embryos possible ; v ) the gfp gene can be easily excised via cre - mediated recombination between the two loxp sites after the expression vector has been integrated into chromosome ; vi ) the two incompatible lox sites, loxp and lox2272, would facilitate cre - recombinase mediated cassette exchange ( rmce ), which in theory will leading to develop a technology of site - specific gene expression in animal mammary glands

    該載體的特點是：具有可以調控外源基因在乳腺中特異表達的牛-酪蛋白基因5 `端側翼區和包括第一外顯子及內含子在內的5 `端調控區；將人血清白蛋白cdna準確地置於牛-酪蛋白基因第二外顯子中的翻譯起始密碼子atg之後，而且沒有增加額外的序列和使人血清白蛋白cdna移碼；引入標記基因gfp ，便於在胚胎期鑒定陽性胚胎，減少受體；引入cre lox重組系統： （ ? ）標記基因gfp的兩端的兩個loxp位點可以在表達載體整合到基因組后，刪除標記基因； （ ? ）餘下的一個loxp位點可以和前面的lox2272位點組成cre重組酶介導的盒式交換系統。
  3. ( 4 ) the photocatalytic activity tio2 - fe2o3 composite film is superior to that of pure tio2 film as the content of fe2o3 is lower which attribute to the separation of photo - induced carriers between in the semiconductors having different energy level. the photocatalytic activity is the best as the mole content of fe2o3 is about 0. 5 %, and the hydrophilicity is the best as the mole content of fe2o3 is about 0. 05 ~ 0. 1 %. but the photocatalytic activity and hydrophilicity of the stromatolith and the composite stromatolith films of tio2 and fe2o3 are not good because the recombination rate of photo - induce

  4. According to the theory of one - level recombination center, a simple analysis of the relations between the trap 、 recombination center and the level position is given

    利用單一能級復合中心理論，分析了雜質和缺陷作為陷阱和復合中心與能級位置的依賴關系
  5. Abstract : according to the theory of one - level recombination center, a simple analysis of the relations between the trap 、 recombination center and the level position is given

    文摘:利用單一能級復合中心理論，分析了雜質和缺陷作為陷阱和復合中心與能級位置的依賴關系
  6. Proofreading activity and low replication fidelity in vitro, distributive manner in dna synthesis, poor ability to discriminate nucleotides at the level of binding and also the possibility of its expanded roles in long patch ber, ner, dna replication and recombination at its excess state

    Lp表現出很低的dna復制保真度：它沒有3 』一5 』外切酶活性因而在a復制中缺乏校讀活性：對底物dn p鑒別能力低卜在長單鏈模權上催化dna復制時散布式的合成方式。
  7. We also have analyzed the photoluminescence ( pl ) spectra of some zno films, it turns out that the emission of ultraviolet light comes from the radiative recombination of excitons within nano - crystal energy band - gap, and the pl peaks move to smaller wavelength because zn are substituted by fe, co, and cu, which cause the size of the film grains smaller and the effective band - gap bigger. the red emission of zno films is due to, on the one hand, decrease of the film grains size which causes the emission intensity smaller and smaller until it disappears abruptly, on the other hand, the transition of electrons from deep donor level of the oxygen vacancies to the valence band

    另外，我們還對薄膜光致發光性質進行了分析和研究，結果表明：納米結構zno薄膜的紫外發光來源於帶間激子的輻射復合發光， pl譜的帶邊發射峰發生藍移是由於fe 、 co 、 cu對zn的替代使薄膜粒子的尺寸減小，使薄膜的有效帶隙增寬； zno薄膜的紅色發光，一方面是zno顆粒尺寸的減少，帶間的激子發射峰越來越弱直至猝滅，另一方面主要是與zno晶格中的o空位有關，由深能級復合發光引起紅光發射。
