In this study, we examined class 1 and 2 integron in shigella sonnei and shigella flexneri isolates from hangzhou, china, to investigate their distribution and determine their gene cassette arrays and their location in genome. a atypical class 1 integron without 3 " conserved region was found to prevail among shigella flexneri isolates, and the excision models of it ' s gene cassette were charactered by inverse pcr. moreover the roles of gene cassettes in the atypical class 1 integron and class2 integron to confer resistance were discussed
本研究對杭州地區近年分離的福氏和宋內氏志賀菌株進行類和類整合子的檢測，了解其分佈特徵；進一步通過克隆測序和southenblot ，確定其攜帶的基因盒組成特徵以及其在基因組中的位置；在研究中發現了一種缺少3 』保守區的非典型類整合子，通過反轉pcr了解此整合子的切除基因盒的特徵；並對非典型類整合子和類整合子各自攜帶的aada賦予宿主菌鏈黴素抗性的不同能力，進行了探討。With the introduction of the dopants, the effective mass of carriers was changed and the seebeck coefficient was increased. at the mean time, the dopants reduced the forbidden energy gap, which changed the carrier concentration and thus increased electrical conductivity. by calculating the forbidden energy gap and electrical conductivity of mg2si specimen doped with different amount sb, the mechanism of transference changed abruptly at 625k
在mg _ 2si熱電材料基體中摻雜te 、 sb元素后，在結構中引入了缺陷，增大了體武漢理工大學博士學位論文系中載流子有效質量，提高了seebeck系數;降低了體系導電活化能，提高了電導率，同時也降低了熱導率。
