During the postgenomics era the information about genomic sequence and gene functions provides a new foundation for evolutionary biology and ecology As the first whole-genome sequenced plant Arabidopsis thaliana and its wild relatives have played a critical role in understanding the evolution of genomics and speciation Both A halleri and A lyrata are closely related to the model species A thaliana A halleri ssp gemmifera occurs in northeastern China Japan and Taiwan; while its sister A halleri ssp halleri is mainly distributed in Europe Geographical barriers such as Tienshan Mountain Range isolate these intraspecific sisters Likewise A lyrata ssp kamchatica and ssp lyrata occur in East Asia and North America respectively Such distribution patterns seem to be consistent with allopartic speciation The comparison between ancestral and extant polymorphism by multilocus can be informative about the population genetics of speciation In this study we collected and analyzed DNA sequences of 98 genes from four wild relatives of A thaliana A halleri ssp gemmifera A halleri ssp halleri A lyrata ssp kamchatica and A lyrata ssp lyrata The ancestral states of these four species were compared to each other in terms of level of genetic variation However the ancestral species at the time of speciation were substantially more polymorphic than the extant geographical populations The observations are not fully compatible with speciation by strict allopatry At some species pairs parapatric speciation seems more reasonable in speciation of Arabidopsis The 98 gene sequences are also used for the congruence test between gene genealogy and species phylogeny Only 28 genes support the species phylogeny but there are 23 genes supports another major genealogy { lyrata} thaliana Based on the phylogenetic position change of A lyrata ssp kamchatica and Ks value for each species pair suggested the recent directional gene flow between A halleri ssp gemmifera and A lyrata ssp kamchatica
阿拉伯芥是第一个完成基因体定序的开花植物,其基因体资讯提供植物学研究的重要依据;在解析阿拉伯芥属物种的亲缘关系以及种化机制等重要的演化议题时,阿拉伯芥近缘的野生物种自然成了不可或缺的关键;跟阿拉伯芥近缘的物种包括A halleri及A lyrata,其中A halleri ssp gemmifera主要分布於中国东北、日本以及台湾,与近缘的A halleri ssp halleri其分布於欧洲隔著天山及大陆的障蔽,而A lyrata ssp kamchatica主要分布於东北亚及台湾,与分布於北美五大湖的A lyrata ssp lyrata被北极圈所分隔,这样的分布模式暗示异域种化的可能。藉由多基因分析比较祖先物种与现生物种遗传歧异度的相关可提供讯息探讨种化时期的族群遗传结构,本研究针对A halleri ssp gemmifera、A halleri ssp halleri及A lyrata ssp kamchatica、A lyrata ssp lyrata四个物种,两对互为亚种的姊妹群,以阿拉伯芥为外群进行研究,在四个物种完成98个同源基因的分子序列,利用套装软体MCMCcoal来估算祖先物种的遗传变异,亦估算现生物种的核苷酸歧异度,观察到?多物种配对中祖先物种遗传多型性大於现生物种DNA歧异度,显示异域种化模型并无法完全解释阿拉伯芥属物种的种化模式,在某些物种配对间邻域种化模式应比异域种化更为可能;在基因树与物种树的比较,98个基因片段的亲缘模式只有28个是与已知物种树一致的,有23个基因其树状图支持{ lyrata} thaliana的型式,藉由kamchatica位置的变化以及估算各物种配对间的平均同义置换率,推测在A halleri ssp gemmifera与A lyrata ssp kamchatica间具有近代的单方向基因交流。

The thinkers of the Lunyu School fully expressed their persistence of individualism and their reconsideration in literary modernity Yet the persistence and escape existed side by side, this mode of behavior and thinking indicated that the self-subject of the modern scholars was illusive and was hard to carry on when the modern scholars were covered by the powerful tradition and deeply controlled by modernity's consciousness of time Chapter Two Reconsidering on the character of modernity with leisure ampleness, resisting the human alienation caused by modern materialism and mechanism with humor, reaffirming the space of self-expression, which formed the humor, the leisure, the modern, and the aesthetic spirit implication of Lunyu School But the modern scholar's powerful inclining to the tradition made Lunyu School's aestheticism draw close to live in seclusion And its aesthetic modernity is also discounted for that reason Chapter Three It is the emotion and the leisure manner owning by the middle aged people that help to bring about Lunyu School's essay's adjusting in main key and moving massively in theme Lunyu School changed the way for "gaining the experience of life"in the twenties'prose It went from highly enthusiastic writings to reserved life-concerning and recite with appreciation in everyday life
第一章 三十年代左翼文学以其"新"、"进步"和"时代性"确立了自己的合理性地位,而时代思潮的转换、文艺与政治的日益密切使五四自由知识分子所坚持的个人主义成了"落伍""颓废"的表征。论语派自由思想者充分表达了对个人主义的执着、对文学现代性的反思,但坚持与逃逸并存的行为与思维模式表明现代士子在忧生伤世的强大传统笼罩下和一往无前的现代性时间意识的深刻控制下,个人主体的难以为继和虚幻性。第二章以闲适的余裕对奔竞躁进、汲汲功利、一往无前的现代性特征进行反思,以幽默对抗现代物质主义机械主义对人灵智的异化,重申自我表现的空间,构成论语派幽默闲适的现代性审美精神内涵。但现代文人对于传统的强大趋同力,则使论语派审美主义向隐逸文化靠拢,其审美现代性由此大打折扣。第三章中年情感与闲适气度直接促成论语派散文基调上的调整及主题的大幅横移,在趣味、游戏、幽默、闲适中改变了二十年代散文"问世"的径路,从意兴湍飞的激扬文字走向了沉潜适世的生命关怀与日常人生的吟味与咀嚼。

Except the foreword, this paper is divided into four chpaters:Chapter One: the common vivid featrues of dramatic personae in the phyletic biography of people in Shiji. The charater accords with the described methods, it has the obvious feature of kindred, It leans to the type of the figural creation in our country's later gerneration novels.Chapter Tw phyletic biography of people not extrudes the common featrue of drmatic personae but also emphersizes the personality description. The figural creation turns personal description from typical description gradually in the later generation novels, although the same typical charaters have the differnt lookings.Chapter Three: phyletic biography of people stands out the charaters with the typical events, the same charater can appears the differnt phyletic biography of people, it shows the differnt features (This is the commuteritive incarnate in Shiji). The later generation novels figure the charaters with their action, the same character lean to the differnt points, they show their differnt characteristics.Chapter Four: phyletic biography of people has the multiform modality, it includes paratactic description, coherend interclude, cascade rising and so on. The later generation novels use for reference the paratactic in the arrange of polt structure.

Firstly, we investigate the influence of the hole injection layer on the performance of the OLED. Evidence shows that m-MTDATA exhibits a dense film structure and fine surface morphology, leading to easy hole migration. Furthermore, a low-voltage driving of OLEDs has been achieved by doping 4F-TCNQ into m-MTDATA layer. Secondly, we obtain a highly efficient OLED by using a new oxidiazoles, an efficient electron-transporting molecular materials. Finally, we have realized the efficient electron injection and transport in organic light-emitting diodes using an electron-transport layer composed of BPhen with Liq co-deposited layer. With this cohost strategy, we improve the power efficiency by~21 % while reduce the driving voltage by~13%.
