In studies of interaction among pile, platform that above it and surrounding soil, this paper employ the concept of plate element to simulate the loading character of platform, and employ the concept of solid element to simulate the character of pile and soil, using the finite element method after understanding the geometry properties of pile, soil and the platform. Analyzing the loading properties of the three entities above and their deformation, this paper also employ a special element, Penalty Element. The introduction of penalty element of this kind has served to guarantee the join harmony of displacement between solid element and plate element, thereby effectively resolving the join problem between platforms, pile that support it and surrounding soil.Considering significant property difference between pile material and its surrounding soil, there may be much shear stress on their contact interface produced under vertical load, thus causing displacement or fission. Therefore it is necessary to adopt one special constitutive law of this kind of contact interface, which can reflect its feature of loading and deformation thoroughly. On the basis of the deformation feature and constitutive laws of some contact interface obtained by Zhang Dongji and people concerned through some single-shear experiments on contact interface between structure and soil, this paper employ one pile-soil three-dimensional constant thickness contact interface model to simulate the " slide" taken place on the interface between pile and its surrounding soil. With this kind model, this paper has also created one finite element model, which can be applied to perform finite element calculation and analyze the pile-loading feature, and deduced its element stiffness matrix.

在承台-桩-土共同作用中，考虑桩与承台的几何特性，采用有限元方法，用实体单元模拟桩土，用板单元模拟承台，更具体地分析桩和承台的受力特性和变形，而且还采用罚单元—既实体单元与板单元之间连接必须满足变形协调条件，来有效地解决了承台与桩土的连接问题，且在桩土共同作用中，由于桩体结构的材料性能与周围土层性质相差较大，在竖向荷载下有可能在其接触面上产生较大的剪应力从而导致错动或开裂，因此，为了充分反映桩土接触面上的受力及变形特征，应采用一种桩土接触面特有的本构关系，即利用张冬霁等人关于结构与土体接触面单剪试验所得到的接触面变形特征及其本构关系，引入桩-土三维等厚度接触单元来模拟桩与桩侧土之间的&滑移&，在此基础上建立可用于桩基承载性状分析的有限元计算单元模型，并推导出了各单元的刚度矩阵。

For example, I speak to the students and the other another distinction, I have another first in the "an" and "other" Draw a vertical line. then inspire students under the Articles, The distinction between an ponder another and the other on the difference between through the analysis of two Articles 2 and indefinite pronouns between the common feature then from the indefinite article and the article migration between the different mentality out indefinite pronouns between two similar distinction.

例如，我在给学生们讲the other与another的区别时，我就先在another的&an&与&other&之间画一条竖线，然后启发学生根据冠词the、 an之间的区别去思考the other与 another之间的区别，即通过分析两个冠词与两个不定代词之间的共同特征，进而从不定冠词和定冠词之间的不同迁移思维出两个不定代词之间类似的区别。

The cultural conflicts existing in Chinese ancient city literature between essentials and nonessentials, between urban and rural areas, between justice and interest and between love and etiquette are still the basic cultural matrix of the Chinese city literature in the 20th century, but they only appear in the historical context that China is becoming modernize, and in the conflicts between traditional and modem cultures and Chinese and western cultures.

中国的传统文化本质上是农业文化、宗法文化，传统的城市文化浸淫在无边无际的乡村文化的大海之中，它虽然有不同于乡村文化的某些新质，但它并不构成与乡村文化的抗衡，城市不能成为一种新的文化的堡垒，而只能成为连接乡村文化的释站。中国近代城市的兴起

Holbrook Working, a pioneer in hedging theory, called this strategy "speculation in the basis,"[1] where the basis is the difference between the hedge's theoretical value and its actual value (or between spot and futures prices in Working's time).

A large number of results from the study indicate that there is a close connection between stock price and trading volume. This paper uses econometric tools, draws on the plasticity and elastic conceptions in the mechanics fields and considers the relation between stock prices and trading volume in different aspects, in order to set up complete stock price plasticity and elasticity theory and apply this theory by carrying on empirical researches.

首先，本文介绍了股价波动的塑性和弹性理论的思想来源，定义股票均衡价格、股价塑性、股价弹性等新概念，通过选取某些个股在不同时段上的股价和成交量的走势图，分别说明了塑性和弹性现象的存在；然后建立了股价的塑性模型、弹性模型及弹塑性交叉模型，应用计量经济学方法对这些模型进行参数估计和检验，对模型进行理论解释，分析模型与现有投资分析理论的一致性；最后是对股票价格塑性模型和弹性模型的应用研究。
