  1. In this paper, first strand cdna of 3abc gene was synthesized using template rna extracted from cells infected with fmdv. the complete 3abc gene about isoobp was amplified by pcr and ligated into pgem - t easy vector. after transforming e. coli dh5 a, ampicillin resistant colonies were isolated and plasmid dna was prepared and analyzed by restriction analysis and pcr. presence of the full length 3abc gene was verified by nucleotide sequence analysis and the plasmid containing the expected sequence was named as pgem - 3abc. comparing the aquired sequence of 3abc with that of reference strains, the homology is more than 99 percent. the pgem - 3abc was digested with sal i and bgl ii and ligated into xho i and bgl ii - digested expression vector ptriex - 4 neo. lt was identified by restriction analysis and pcr and sequencing that this fragment had a 17bp deletion hi the nucleotide sequence 708bp of 3abc gene, which happened to form a terminator codon behind 3ab gene, but it contained the complete open reading frame ( orf ) of 3ab gene. positive clones were selected and induced with lmmol / l isopropyl - d - galactoside ( iptg ), bacteria were detected by sds - page and western blotting after properly treated. the results showed that the 3ab gene expressed successfully in e. coli and 33. 5ku fusion protein can be recognized by the positive bovine serum of fmdv. the amount of target protein is over 26 % of the total bacteria protein by gel thin layer scanning analysis

    擴增產物連接到pgem - teasy載體中,轉化大腸桿菌dh5菌株,篩選氨芐青霉素抗菌落,提取質粒經酶切鑒定、 pcr分析以及確證測序證明,所克隆的1500bp左右的片段含有完整的3abc基因,與國外參考序列相比,同源在99以上。將重組質粒pgem - 3abc和表達載體ptriex - 4neo分別用sal和bgl與xho和bgl消化后,亞克隆3abc基因至核表達載體ptriex - 4neo中,通過酶切鑒定、 pcr擴增以及序列分析,發現克隆到ptriex - 4neo載體上的片段於3abc基因708bp處出現了17bp的缺失,碰巧在3ab基因后形成一終止密碼,但3ab基因的閱讀框架完整,選出含有3ab基因完整閱讀框架的克隆,用iptg誘導表達,收集菌液進行sds - page泳、 westernblotting分析,結果表明, 3ab基因在大腸桿菌中成功表達,其表達產物為分量33 . 5ku的融合蛋白,並能被口蹄疫病毒血清識別。經薄層掃描分析,表達量占總蛋白量的26以上。
  2. Abstract : this paper, by analyzing the effect of differences of mineral structure of 2 1 layer minerals, the properties of their interlayer charge and changes of some properties caused by weathering on the attractive force for interlayer cation, reached the conclusion that : the fixation capacity is determined by the ratio of the total amount of interlayer charge and that of tetrahedral charges. the relationship of interlayer cation fixation and octahedral structure of secondary minerals is probably different from that of primary minerals. the oxidation and reduction of variable valence cations can greatly influence the cation fixation capacity

    文摘:分析2 1型礦物的結構差異、層間質以及在風化過程中某些質的變化對層間吸引力的影響,對已有報道中一些矛盾的結果或不具普遍意義的結論進行了討論.得出幾個較為明確的結論:層間總荷與四面體荷所佔比例大小共同決定礦物對層間的固定能力;生礦物中八面體結構與層間固定間的關系對次生礦物而言,也許並不一致;八面體中可變價的氧化還,可導致礦物固定能力發生較大變化
  3. In 1909, ernest rutherford showed that atoms were mostly empty space, revising the model of an atom to a tight positive nucleus containing the protons and neutrons with electrons around it ; by 1913, danish physicist neils bohr envisioned a planetary arrangement in which the electrons orbited the nucleus at different energy levels

    在1909年,歐內斯特?盧瑟福展示大部分是真空區,修正的模型就是緊密的核包含質和中圍繞中旋轉;到1913年,丹麥物理學家尼爾?波爾想象了一個以不同能量水平面圍繞核旋轉的行星排列。
  4. It has high selectivity in adsorpting water, polar molecule or polarizable molecule on account of the existing of mighty coulomb field and polar interaction in the internal of crystal cave of zeolite, the high electric field gradient and the uneven surface caused by the exposure of exchangable cation of equilibrium framework negative charge in framework structures

    由於分篩晶穴內部有強太理工大學碩士學位論文摘要大的庫侖場和極作用,再加上骨架中大量平衡骨架負荷的可交換的暴露造成的高場梯度及表面的不均,使其對水、極及可極化的分具有高選擇的吸附能。
  5. Al - doped zno thin films are emerging as an alternative potential candidate for ito flims recently. al doped zno thin films also can obtain a tunable band gap. especially, zno : al thin films with high c - axis orientated crystalline structure along ( 002 ) plane are potential device applications in broadband ultra - violet

  7. As a new method of polymerization, electroless polymerization was introduced to form polyaniline film on substrate of any shape. in electroless polymerization, aniline molecules were oxidized to form pn film by soluble oxygen on the catalytic surface of pt or pd substrate without the supply of electric current. similar to the mechanism of electroless plating, electroless polymerization of aniline involves local and spontaneous electrochemical reactions on only substrate

    提出了一種新的聚合方法無聚合。在沒有外流的情況下,溶液中的苯胺分在具有催化活的鉑或鈀基底表面上被溶解氧氧化為聚苯胺膜。與化學鍍的理類似,苯胺的無聚合反應過程包含陰極半反應和極半反應兩個化學反應。
