The paper falls into three parts: firstly, the concept of native folk was definited and the characteristic of native folk was analysed, and then the native folk element presented in modern novels were discussed. Secondly, the forms of expression in different period of the native folk in modern novels represented by writings of Lu Xun,Shen Cong-wen and Zhao Shu-li were analysed. Finally, on the basis of the second chapter, the reason why the native folk has different forms of expression in 30years of the modern literature was further discussed from the writers angle--thedifferent way of clerisies being concerned with native folk.

本论文共分三个部分：首先，对&民间&的理念进行梳理，对&乡土民间&的概念进行界定并分析它的特征，进而具体讨论现代小说创作中所呈现出来的乡土民间这一元素；其次，以鲁迅、沈从文、赵树理的作品为代表来分析现代小说发展不同阶段&乡土民间&的表现形态；最后，承接第二章探讨为什么在现代文学三十年中&乡土民间&具有不同的表现形态，进一步从作家创作的角度来分析，也即知识分子参与&乡土民间&的不同方式。

The writer carries on the related theories of the problem situation to study the big case foundation well up, with the situation cognizes and studies a class of theories for leading, and have three stages to launch to practical research; The first, the research into big case strategy of problem situation and the process of tiding up some materials in the chemistry teaching.

笔者在对问题情境的相关理论进行研究的基础上，以情境认知与学习理论为指导，分三个阶段展开实践研究：第一，化学教学中问题情境创设的策略研究和案例素材的整理加工，包括结合生活、生产和当前科学技术发展中的实际问题创设问题情境，从化学实验入手创设问题情境，利用化学史料创设问题情境，利用学生已有知识创设问题情境或引起学生的认知冲突等。

This part Measures firms" size with market value of float shares, and divides each portfolio into quintiles and deciles to choose an appropriate grouping method. The second part divides the sample into two sub-samples to tests the different performance of "small firm effect" in two periods. The third part tests different performance of each month. The fourth part studies the "small firm effect" in five industries, the industry, the commerce, the public utilities, conglomerates and the properties, and uses Fame-Macbeth method to research "the small firm effect" in the different industries. The fifth part analyzes the reason why the "small firm effect" exists in China stock market referring to the western explanation about "the small firm effect and the character of China stock market. In the end, we provide some suggestion.

论文运用实证方法检验中国股市&小公司效应&的存在性，用流通股市值作为公司规模大小的度量，用五分组和十分组两种分组方法检验中国股市&小公司效应&的表现；把整个样本区间以2001年为界分为两个样本子区间，检验&小公司效应&在不同时间阶段的表现有何不同；分月检验&小公司效应&在不同月份的表现；把样本中所有上市公司按照行业分为五大类，工业类、商业类、公用事业类、房地产类和综合类，利用Fama-MacBeth法检验中国股市&小公司效应&在不同行业的表现；联系国外关于&小公司效应&存在原因的解释，结合中国股市的实际，分析中国股市&小公司效应&存在的原因，并提出了一些建议。

Its rule of change was obtained. On the basis of other studies, the flocculation kinetics and flocs structure was studied. By making some assumptions, collision frequency were presented. Then the the flocculation kinetics model was established through population balance equation. Comparison of experimental data and modeling results indicate that there are the same trend between the two. So the model can predict flocs number and size during flocculation of Yellow River's loess particles without using empirical parameters. The TEM and SEM were used to obsever flocs in the study of floc structure. The flocculation was divided as flocculi, floc and floc aggregate. The flocs structure model was established by assumption that particles position in floc accords with tetrahedron. The fractal dimension of model and experimental flocs was found to be coincident. So the model can reflect the structure of flocs formed in flocculation of Yellow River's loess particles by macromolecule flocculant at a certain extent.

最后，本文还对絮凝动力学和絮体结构进行了研究，在前人研究的基础上，针对高分子絮凝黄河泥沙，对絮凝过程作了一些符合试验条件的假设，建立了颗粒碰撞频率表达式，应用了颗粒数量平衡方程，从而建立了絮凝过程的动力学生长模型，模型计算结果与试验数据对比表明，二者趋势一致，在没有使用经验参数的情况下基本上能够描述黄河泥沙絮凝过程中絮体数量和尺寸分布的变化过程；对絮体结构的研究中，应用扫描电子显微镜和透射电子显微镜对絮体进行了观察，将絮体分为絮粒、絮团和絮网三个不同的生长阶段，通过假设颗粒结合位置符合正四面体，建立了絮体结构模型，计算得到的模型絮体分形维数基本与试验中的实际絮体相符，在一定程度上能眵反映高分子絮凝黄河泥沙生成的絮体结构。
