The 329 bp terminal inverted repeat sequence can't form the conserved fold-back secondary structure as that of many Streptomyces linear replicons. Lacking of typical Streptomyces tap/tpg locus for te-lomere replication, pPR2.3c encodes a protein with two domains resembling the telomere associated protein of Strepto-myces and helicase of Haemophilus respectively. No typical Streptomyces iteron-rep locus for replication from the cen-trally located origin, two DNA fragments containing almost all pPR2 were cloned and introduced by transformation into S.

其端粒末端反向重复序列的长度为329 bp，不能像多数链霉菌的线型质粒那样能形成保守的&折返&的二级结构。pPR2虽然没有参与链霉菌端粒复制的保守的tap/tpg基因，但是pPR2.3c基因编码了一个双结构域蛋白，分别同链霉菌的端粒复制相关蛋白Tap和嗜血杆菌的解旋酶具有相似性。pPR2缺少典型的链霉菌重复序列-复制基因区段，将几乎覆盖全长pPR2的两段DNA进行克隆后，不能转化变铅青链霉菌。

There were 20bp and 7bp direct repeat sequences flanking the prophages 933v and 933w. The flanking repeat sequences are termed as attachment sites.

序列比较分析表明原噬菌体933v的整合位点位于O157：H7 EDL933基因组中第2966137位的相对位置，在整合位点两侧有一个20bp的直接重复序列，原噬菌体933w的整位点位于基因组中第1330826位的相对位置，在整合位点两侧有一个7bp的直接重复序列。

Similar lamellar hybrids can be obtained from octa(y-chloroammoniumpropyl) polyhedral oligomeric silsesquioxanes dodecyl benzene sulfonic acid sodium salt C_(18H_(29)NaO_3S, DBSS. Further research shows that different POSS to surfactant ratios result in different arrangement of layers: when there exists excessive POSS, the layer is arranged in a "Alkyl-POSS-POSS-Alkyl" sequence; while on the contrary, the layer is in "Alkyl-POSS" sequence.

实验研究表明，通过调整POSS和表面活性剂的物质的量比例可以改变片层结构，发现当POSS成分大大过量的时候，片层重复单元按照&烷基-POSS-POSS-烷基&顺序排列，对应较大的层间距；当表面活性剂成分大大过量的时候，片层重复单元按照&烷基-POSS&顺序排列，对应较小的层间距。

On the Quasi- usufruct in Real Law of Our Country;2. Under the premise of the feasible mortgage of the forest property,this article analyzed the feasibility of the usufruct mortgage of forest property from the view angle of historic evolution of the mortgage and the legal system interpretation of the Guaranty Law.

在林木所有权可以抵押的前提下，从抵押权的历史发展和《担保法》的体系解释两个角度，阐述林木用益物权抵押的可行性；分析我国禁止重复抵押的不当之处以及建立林木重复抵押制度的必要性和可行性；主张林木可以与林地使用权分离单独设定抵押权，也可以与林地使用权一并设定抵押权。

Used the method of touch down PCR, the ACS2 gene was cloned from DNA of Petunia hybrida. At the same time, its gene sequence DQ090003 was obtained in GenBank, the antisense repetition of ACS2 linked the plasmid pBI-121 by use of one step. In the result, the expression vector having antisense repetition gene was constucted.

利用降落PCR的方法，从矮牵牛DNA中扩增出ACS2基因片段，在GenBank中获得基因序列号为DQ090003；利用一步法将ACS2基因的反义重复与pBI-121质粒连接，构建含该基因的反义重复表达载体。
