  3. At the initial stage of planar technique, b was employed as ideal diffusion impurity in base - region of npn si planar devices because of the match of its solid - solubility and diffusion coefficient in si with those of p in emission - region, and the good shield effect of sio2 film to b. but because of the relatively large solubility ( 5 1020 / cm3 at 1000 ) and the small diffusion coefficient, the linear slowly - changed distribution of acceptor b in pn junction can not be formed, which could not cater to the requirement of high - reversal - voltage devics. thereafter b - a1 paste - layer diffusion technology and close - tube ga - diffusion technology had been developed, while the former can lead to relatively large the base - region deviation and abruptly varied region in si, which caused severe decentralization of current amplification parameter, bad thermal stability and high tr ; the latter needed the relatively difficult pack technique, with poor repeatability, high rejection ratio, and poor diffusion quality and productio n efficiency

    在平面工藝初期，由於b在硅中的固溶度、擴散系數與n型發射區的磷相匹配， sio _ 2對其又有良好的掩蔽作用，早被選為npn硅平面器件的理想基區擴散源，但b在硅中的固溶度大（ 1000時達到5 10 ~ （ 20 ） ，擴散系數小， b在硅中的雜質分佈不易形成pn結中雜質的線性緩變分佈，導致器件不能滿足高反壓的要求，隨之又出現了硼鋁塗層擴散工藝和閉管擴鎵工藝，前者會引起較大的基區偏差，雜質在硅內存在突變區域，導致放大系數分散嚴重，下降時間t _ f值較高，熱穩定性差；後者需要難度較大的真空封管技術，工藝重復性差，報廢率高，在擴散質量、生產效率諸方面均不能令人滿意。
  4. We cloned full - length cdna of ca coding region via pcr amplification, but a negative result was obtained when the interaction of full - length ca and ga was tested in yeast two - hybrid system

    通過rt - pcr克隆了ca編碼區全長cdna ，但是在雙雜交系統檢測全長ca與g蛋白的相互作用時，結果為陰性。
  5. ( 2 ) deletions of four different lengths were conducted using pcr amplification with the information of sequence of pdf 1. 2 gene promoter. these mutated promoters were fused to the gus reporter gene and introduced into tobacco plants. the results of gus activity driven by these different constructs showed that the promoter sequence between positions - 300 and - 243 ( containing a gcc box and a g box - like sequence ) was an essential ja - responsive element region to activate the expression of gus reporter gene, and the - 300 bp position was defined as the boundary of the minimal functional promoter in response to ja signaling

    （ 2 ）對該啟動子的5 』端進行不同長度的缺失突變，突變的啟動子與gus構建的融合基因在煙草中受meja誘導的瞬時表達結果表明，該啟動子中- 300 - 243bp區域（有一個gccbox和一個gbox - likesequence ）是其應答meja處理所必須的區域，並將- 300bp作為該啟動子應答ja信號的最小區域的邊界位置。
  6. Part two : studies ; l. the sox gene of dinodon refozonatum was amplified by using a pair of primers which can amplify the conservative motif ( hmg - box ) of human sry gene. the amplification band was observed in both male and female dinodon refozonatum, whose length was consistent with that of human sry gene, which about 220bp. the result of sscp analysis showed that there were many differences in the sox gene sequence between dinodon refozonatum and human, and there was a few differences between male and female dinodon refozonatum. 2. using a pair of degenerate primers based on the conservative region, hmg - box, of human sry gene, six different fragments were amplified from either female or male dinodon refozonatum, then cloned by using pmd18 - t vector and sequenced

    結果顯示： （ 1 ）赤鏈蛇基因的擴增片段與人sry基因擴增片斷大小相同，為220bp左右； （ 2 ）雌、雄赤鏈蛇sox基因的擴增片段大小雖然與人的相同，但其單鏈遷移率與人的有較大差異，而且雌雄個體間有明顯差異，預示該基因的dna序列在雌雄個體中可能有差異； 2 、參照人sry基因hmg - box保守區的序列，又設計一對兼并引物，擴增了赤鏈蛇的sox基因，並對擴增產物進行了克隆和測序。

    Rdna的特異性擴增結果表明，供試側耳菌株均可擴增出一條約1 . 46kb的28srdna5 』端特異性片段和一條約680bp的its片段，表明這兩個區域在側耳屬中較為保守，沒有發生長度突變。
