These data suggest that the terminal hairpin structure and ITRs of PfDNV play a key role in the rescue and gene correction process: sequence at the junction of the terminal palindrome of PfDNV genome and the pUC119 can form typical Holliday structure, it can be cutted by the special endonuclease, then the exposed 3'hairpin structure serving for a self-primer to initiate viral DNA replication; and the intact extremity acting as a template to repair another altered end within inverted terminal repeats.

说明存在着一种拯救和基因修复机制，推测与PfDNV基因组末端结构（Hairpin、ITR）有密切关系：PfDNV基因组与pUC119质粒连接处可形成Holliday结构而被识别该结构的核酸内切酶所切割，游离下的基因组3'发夹结构作为引物起始复制，然后被置换链的完整的5'ITR作为模板修复部分缺失的另一端ITR，推测这个过程需要病毒NS蛋白以及细胞因子的参与。

The calculated NICS values show that nucleus-independent chemical shifts values of roof-shaped isomers for Sb42-, Bi42-, and22- species are all negative, consequently indicating that these roof-shaped isomers possess aromaticities.

In this thesis, the radiation principle and the structure of slot antenna are studied and the impacts on its performance of every structure parameter in a slot antenna design are analyzed. On this foundation, a design plan of planar slot array antennas is proposed. The design has some structural feature as follows:(1) with different dielectric layers and microstrip line structure to guide the electromagnetic wave effectively;(2) the feeding network formed of microstrip line can match with the radiating slots expediently;(3) in order to increase the bandwidth of the antenna, the wider slot and branched feeding microstrip line are adopted to form a double resonance.
