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。

Third-Party Logistic of Warehouse Management System Framework provides a series of reusable groupware, such as persistence layer which introduces Dynamic Value Object, Value List Hander and Command pattern. It encapsulates the details of accessing database and affords the interface of different persistence layer framework. Based on Asynchronous JavaScript and XML, we develops the client validity check engine, dynamic cascading menu and common, dynamic tree structure groupware, as well as a set of tag library which include query, pagination, cache and so on. It reduces the code redundancy and predigests the development of interface layer enormously.

1Niche construction can lead to stable coexistence of diverse genotypes in spatially structured population, which supports a stable polymorphism even without heterozygote superiority.(2)With habitat deterioration, niche construction accelerates the formation of steady polymorphism and hence impedes the harmful influences of environment on the population, which might embody a life-history strategy of organism under the unfavorable environment.(3)Niche construction results in the coexistence with alternative polymorphism through genotype-environment feedback and limited gene flow.(4)The niche-constructing organism is an active force to alter its environment and hence the direction of natural selection in order to better survival.(5)Spatial dynamics and distribution pattern of metapopulation are profoundly influenced by time-lagged niche construction.(6)Metapopulation size can reach a fixed level in the recency effect and equal weighting of time lag but is statistical stability in primacy effect, which implies the primacy effect is most remarkable.(7)The increment in the relative weightingof each generation\' niche construction and the length of time lag are significant factors for system destabilization.(8)Moderate capacity of positive niche construction benefits the metapopulation persistence.(9)The narrowing of niche breadth can decrease the metapopulation size and thereby increase the extinction risk.(10)The coupled function of time lag and niche construction make the system oscillation and generate the spiral wave, spiral-broken and circular wave in heterogeneous habitat.The spatial distributions of metapopulation and resource content are complementary due to a phase lag of their both frequencies.(12)Metapopulation persistence with niche construction depends not only on the balance between colonization and extinction, but also on the balance between the ability of niche construction and natural dissipation of habitat.(13)Metapopula-tion can survive under certain condition when the percent of suitable patches in habitat is lower than the ration of extinction to colonization.(14)Two thresholds exist in the process of transition of habitat quality dynamics from unsuitable to suitable, which include the intensity of niche construction and the initial condition of system.(15)Metapopulation size is positive correlated with the ability of positive niche construction, which means that organism or population who has strongly positive influences on their environment plays an important role to maintain the available habitat.

通过上述几个方面的研究，主要得出以下15条结论：(1)生态位构建可使空间结构种群，甚至是在没有杂合子优势的条件下，形成多种可能的稳定基因型分布模式；(2)随着环境的破坏与恶化，种群的生态位构建作用加速其较早形成稳定多态以阻碍环境对种群的不利影响，解释了有机体在不利环境下的一种生活史对策；(3)生态位构建作用通过基因型—环境反馈机制及有限的基因交流导致基因型多态的稳定共存；(4)有机体的生态位构建作用是一种积极的动力改变环境进而改变其自然选择的方向；(5)生态位构建的时滞作用对集合种群动态和空间分布产生深刻影响；(6)集合种群大小在时滞的崭新效应和等权重效应下达到一固定值，而在首位效应下达到统计稳定，表明首位效应的影响最显著；(7)首位效应下生态位构建相对权重的增量和时滞的长度是影响系统不稳定性动态的关键因素；(8)适中的生态位构建强度有利于集合种群的续存；(9)生态位宽度变窄会减少集合种群的数量从而增加其灭绝风险；(10)时滞和生态位构建的双重作用使系统产生周期振荡，并在异质性环境中产生稳定的螺旋波，破碎的螺旋波和环形波三种分布模式；(11)集合种群与资源含量的空间分布因为相滞而互补；(12)具有生态位构建的集合种群续存不仅取决于侵占率与灭绝率之间的平衡，而且依赖于生态位构建能力同其生境的自然消耗速率之间的妥协；(13)当生境中适合侵占的斑块比例小于其侵占率与灭绝率之比时，生态位构建作用促使集合种群在一定条件下续存：(14)生境斑块的状态从不适合到适合转变过程中存在生态位构建强度和系统初始条件这两个阈值；(15)集合种群的大小同正生态位构建能力正相关，意味着对环境具有较强正作用的有机体对维持有效生境起积极作用。
