Characteristics of the Internet traffic data flow are studied based on the chaos theory. A phase space that is isometric with the network dynamic system is reconstructed by using the single variable time series of a network flow. Some parameters, such as the correlative dimension and the Lyapunov exponent are calculated,and the chaos characteristic is proved to exist in Internet traffic data flows. A neural network model is constructed based on radial basis function to forecast actual Internet traffic data flow.

摘 要：应用混沌理论，分析了网络流量，用单变量的网络流量时间序列重构与网络动力系统等距同构的相空间，进而计算了实际网络的关维数和Lyapunov指数，并证实了网络流量存在混沌特性；据此建立了基于径向基函数神经网络的模型，并对实际网络数据流进行了预测。

With this aim , this paper has made a comprehensive study on the problem of the land requisition in our country . armed with such renowned theories as the theory of property right application , land rent , public choice etc ., the study has rendered a potent analysis of the problems involved in the current land requisition policy and their reasons . then , based on china ' s realities , it advances its own proposal to renovate the current policy from various aspects including the nature and limitation , the procedure and the standard of compensations of the land requisition , that is , by means of a combination of enumeration and generalization , decide on a strict definition of public interests ; improve the procedure of the requisition of land under the principle of openness , justice and high efficiency ; set up the compensation standard with the market price as the baton while versified by other supplementary ways ; most importantly , clarify the property right of land

本文通过对土地征用问题进行系统、深入的调查研究，针对当前我国土地征用制度存在的主要缺陷和弊端，应用产权理论、地租理论、公共选择理论、新制度经济学中的路径依赖理论以及其它相关理论分析土地征用存在的问题及其原因，并结合国内外的先进经验，立足本国实际，从征地性质与范围的界定、征地程序的完善，以及征地补偿标准的确定，提出了完善土地征用制度的政策建议：采取列举式和概括式相结合的方式，严格的界定&公共利益&范围；树立正当的程序观念，按照公正、公开与效率的原则，完善征地程序；建立以市场价格为主的土地征用补偿标准，建立多样化的征地补偿方式等来解决我国征地中存在的问题，但最根本的是明晰土地产权从而进一步完善我国土地征用制度。

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.
