Prepared technical parameters were optimized by l9 ( 34 ) experiment analysis. a unique method for cleaning and drying of substrate - cleaning used by scour, drying used by infrared light was fished out by large numbers of experiment. chemical mechnism of zno thin film prepared by sol - gel technique was discussed by dta for the first time. by the measurements of sem, xrd and uvs, the thin film was analysed. the result proved that the thin film with strongly preferred orientation of c - axis perpendicular to the substrate surface which surface was homogenous, dense and crackfree was the crystalline phase of hexagonal wurtzite. the thin film was composed of plentiful asteroidal crystal which crystal dimension approximately 10 30nm. the average transmittance of thin film in visible region was above 90 %. the results of measurements else also proved that the thickness of single dip - coating was 75 240nm, this films resistivity was found to be 3. 105 102 3. 96 105 ? cm. the thickness and resistivity of thin film influenced by dope - content, withdrawal speed, pre - heat - treatment, anealing were reseached respectively
利用xrd 、 sem以及uvs光譜儀等分析方法對薄膜進行了研究，結果顯示，所制備的薄膜為六方纖鋅礦型結構，具有高c軸擇優取向性；表面均勻、緻密，薄膜材料由許多星狀晶粒組成，晶粒尺寸大約為10 - 30nm左右；薄膜可見光透過率平均可達90 % ；對薄膜厚度以及電學性能進行了測定后發現：單次鍍膜厚度約為75 - 240nm ， al ~ （ 3 + ）離子摻雜型氧化鋅薄膜的電阻率在3 . 015 102 - 3 . 96 103 ? cm范圍內；分別研究了摻雜濃度、提拉速度、預燒溫度、退火溫度等工藝參數對薄膜厚度和電阻率的影響。 -
In order to get small molecular g - protein rab3a, which serves to further investigate the interaction between rab3a and other proteins, we amplified the full coding region of rab3a cdna by polymerase chain reaction, using human placenta total cdna as template. the pcr products were recovered from gel electrophoresis and cloned into bamhi xhoi site of vector pyestrp2. the result of sequencing indicated that rab3a insertion fragment included its initiation and termination codons in 5 - and 3 - terminal, respectively
為了獲取全長的小分子g -蛋白rab3a ，以用於研究rab3a與其他蛋白相互作用關系，本實驗以人胎盤總cdna為模板， pcr擴增到人rab3a cdna全編碼區。產物回收后克隆于質粒pyestrp2的bamhi xhoi位點，測序結果表明，本實驗獲得的rab3a cdna包含了起始和終止密碼子。
