Along with the ebb-tide of the enlightment and the historical conversion from cultural enlightment to political revolution, the utilitarian pursuance of literature must have a corresponding change, and only so could it get avoid the rattrap.

文学革命是作为启蒙思潮附着物而存在的，随着启蒙的落潮、历史变革由文化启蒙转向政治革命，文学的历史功利追求由文化启蒙转向政治革命既是历史的必然，也是文学摆脱启蒙困境的一种自觉选择。

The basal geomorphology structure of the Tidal-Basin System of the Tiaozini Sandbanks is watershed and tidal creek system. We analyses its formation, evolvement, geomorphology characters and development and discusses the main influence factors which is water, sediment and space. We divide the evolution phases which is formation phase, autumn phase and contabescence phase. In the end we confirms its main functions, which is discharging the folium water on the tidal flat of the Tidal-Basin in the end of the ebb-tide, transporting sediment to Tidal-Basin through tidal creek systems, confining the swing range of the dynamical axis of flood tide or ebb tide, balancing the dynamical status of the South and North. At the same time, we compare coastal tidal-basin and sandbanks tidal-basin on geomorphology characters, formation causes, style and so on.

条子泥潮盆—潮沟系统的基本地貌结构为分水滩脊和潮沟系统，本文分别对它们的形成与发育、地貌特点及动态变化进行了分析，并探讨了影响其发育的主要因素，即来水条件、来沙条件、空间条件，划定了其主要发育阶段，即形成期、成熟期、衰亡期；在上述分析的基础上确定了潮盆—潮沟系统的主要功能，即通过潮沟系统渲泄落潮后期滞留在其潮盆范围内的滩面薄层水、通过潮沟系向潮盆内部输入或输出泥沙、限制涨落潮动力主轴摆动范围、平衡南北两侧动力状态；同时针对岸滩潮盆—潮沟系统与沙洲潮盆—潮沟系统的地貌特征、成因类型等进行了对比分析。

ABSTRACT After the ebb-tide of the May 4th Movement, the Chinese modern thoughts and literary circles went from relative unity towards diversity Up to the 1930's, behind the spirit transformation at the end of the twenties, Chinese modern intellectuals began to relocate and redesign their own outlooks on life and literary ideal The Lunyu School, which was led by Zhou Zuoren and Lin Yutang, mostly appeared as leisure humorous essays in some journals, such as Lun Yu, Ren Jian Shi and Yu Zhou Feng which was edited by Lin Yutang It formed an unique landscape at that time This thesis focused on the Lunyu School as the main object of my study I investigate the Lunyu School by putting it into the vertical orbit of changes of the thoughts and literary circles after the May 4th Movement, and by comparing it with the mainstream of Left-wing and other literary schools in the thirties Through the exploration of Lunyu School's political and social thoughts, literary ideas and aspects of prose creation, I pursue the life choice of some free intellectuals in the thirties, and draw psychological outline of an age of intellectuals, which was very complicated and attractive during that specified time and space When we reconsider the rights and wrongs, the merits and demerits, and the gains and losses in theory and creations of Lunyu School intellectuals, any oversimplified study method would be of"no avail but the waste of mind"Unless ample estimation of their own complexity and contradiction is made, furthermore subtly delineates quite a lot of originates which caused these complexity and contradiction, the research will not be valuable In face of the whizzed coming Left-wing movement in literature, Lunyu School acted as a reconsideration in literary modernity such reconsideration is a layer of thinking They introspected intellectuals'essential mind and enlightened reason, querying the impulsive, swift and fierce ideological trend, judging by value in the relations between individuality and society, individuality and era, literature and politics.

五四落潮后，中国现代思想界、文学界由相对统一走向分化，至二十世纪三十年代，现代知识分子经由二十年代末期的精神蜕变，开始重新定位和设计自己的人生观和文学理想。以"京兆布衣"周作人为精神领袖、以林语堂为主帅的论语派，以幽默闲适小品文相号召，在林语堂主编的一系列刊物《论语》、《人间世》、《宇宙风》上聚集，南北呼应，造成了当时文坛的一种独特景观。本论文以论语派为研究对象，将其放在五四以后文学界与思想界变动的纵向轨迹上，放在与三十年代左翼主流话语的颉颃及与其它文学流派的比照中加以考察，通过对论语派政治社会思想、文学观念及散文创作诸方面的探讨，追索三十年代一部分自由知识分子的人生选择，勾划出他们在一个特定时空里复杂又极具魅力的心理轮廓。学术界对论语派中一些主要作家已有较深入的研究，但迄今为止，尚无从整体上对这一文学流派作宏观研究的专著，而陈旧的理论视界又往往阻碍了对论语派的重新评价。

On the basis of previous study on deep channel, the South Branch,Xinqiao Channel,Nanxiaohong and Main Channel of Nangarg are chosen as the typical flood and ebb channels. Field data sampled in the flood season of 2001 and the dry season of 2003 are used as the base of the analysis of hydrodynamic characteristics, such as current, sediment, dominant current and dominant sediment.

在前人对河口冲刷槽研究的基础上，选择长江口南支、新桥水道、南小泓和南港主槽作为典型涨、落潮槽研究对象，以2001年洪季和2003年枯季实测资料为根据，比较分析了长江口涨落潮槽的水流、泥沙、优势流和优势沙等动力特征，结果表明用单一因子分析河槽性质不够全面。

The intertidal zone is the shoreline between the high and low tide marks.

他们喜欢在落潮时沿着海滨散步。

Spring and neap tide will occur twice per month in Yangtze estuary.

长江口附近潮汐为半月潮，每月有两次涨落潮，鳗苗溯河量与潮汐周期呈现一定的节律性，每月有两次鳗苗峰值。

Blocked by the scheduled project, the tidal current near the coast will move around the project. 4. Changes of SSC before and after the project The general characteristics of the SSC both before and after the scheduled project are as the following: the SSC is lower in the waters of the project ranging from 11 mg/L to 19 mg/L; the SSC isolines are generally parallel to the isobaths, decreasing towards the coast; the SSC in flood tide is higher than that in ebb tide, so are high tide and spring tide than low tide and neap tide, respectively.

4工程前后悬沙量变化工程前后悬沙分布的基本规律：在工程海域，悬沙量均保持为较低值，大致为11～19mg/L；悬沙等值线基本平行于等深线，随深度的减小浓度减小，一般到近岸区达到最低；悬沙量的日周期性变化规律明显，悬沙量涨潮时大于落潮时，高潮时大于低潮时，大潮时大于小潮时。

Results show that floes' VC and D at the surface water were closely related to current velocity; and the peaks of VC lag those of the current velocity. The lag variation during ebb and flood tides is 10-30min and 30-50 min, respectively. Current velocity at 50 cm/s is a turning point of D vs. vertical average current velocity, before the point, Dm increases with current velocity, and decreases after the point. Similarly, VC at 75μl/L becomes a critical point in the surface water, below the point, D increases with VC, and above the point, D stabilizes.Δp is D dependent, larger floes have much lower Δp than smaller floes. Both D and Δp of floes affect ω. In the surface water during spring tide and neap tide, a power exponent relationship exists between Δp and D, and ω and D.

研究表明：①长江口徐六泾表层絮凝体体积浓度主要受水流流速影响，再悬浮现象明显，体积浓度过程线滞后流速过程线，落潮期间滞后10-30min，涨潮则滞后30-50min；②小于一定流速时絮凝体平均粒径随流速增大而增大，大于一定流速时絮凝体平均粒径则随流速增大而减小，徐六泾夫、小潮表层絮凝体在50cm/s的垂线平均流速时出现平均粒径与垂线平均流速关系的转折；③徐六注大、小潮表层絮凝体平均粒径在体积浓度75μl/L时出现平均粒径与体积浓度关系的转折，体积浓度小于75μl/L时粒径随体积浓度增加而增大，超过75μl/L时粒径随体积浓度的增加变化不明显；④絮凝体有效密度由粒径大小控制，粒径大，有效密度小，反之亦然，粒径和有效密度共同决定絮凝体静水沉速，有效密度和沉速与平均粒径之间均存在良好的幂指数关系。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
