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。

A special type of half-plane problems of elasticity is presented and discussed. By using two methods in polar coordinates and orthogonal coordinates respectively, the analytical expressions of stress components are solved in the two coordinates. There are little differences between both results, which confirm the equivalence of the two methods.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
