The paper obtains some conclusions after many theories analysis and empirical tests: Firstly, Volume-price relativity is extensive: total volume or it's change, disassembled volume promoting price movement or it's change all has plus relativity to equilibria price. Secondly, there is unilateralisms Granger casuality in bullmarket, while there is bidirectional Granger casuality in bearmarket. There is not nonlinear Granger casuality in both markets. Third, Behavior finance has remarkable effects after contrasting to different investment conditions. Moreover, causality research by moving tendency can reflect the stable relation while usual causality research can't do. Fourth, it can be ture forecasing key period of tendency reversion by building volume-price elasticity coefficient containing composite information of volume-price and analysis methods of moving tendency.
本文大量的理论分析和实证研究得到以下结果:第一,量价之间的相关性具有广泛性,总成交量及变化、分解的促进股价变化的成交量及变化都与均衡价格收益有正相关关系;第二,在牛市中,收益和成交量之间存在单向的Granger因果关系,而在熊市中,收益和成交量之间存在双向的Granger因果关系,不论熊市和牛市,上证和深证量价间均没有非线性因果关系;第三,不同市场环境的比较中还发现行为金融在股市中的作用明显,通过比较发现依据运行趋势的因果关系分析能反映量价间的稳定关系,而常规因果分析方法却反映不出来;第四,通过建立包含量价信息的量价弹性系数指标和依据运行趋势的关键区域研究法,可以实现对趋势转变关键区域的预测。

Firstly, we research the Vlasov antenna with reflector mainly. A new method to calculate the radiation of the antenna is founded with Vectorial Theory of Diffraction, and the corresponding program is made. The reflective characters of Vlasov antenna are studied with Moment Methods, and the results show that the total reflected energy is less than 0.25%. The radiation patterns of the antenna are analyzed, and the formulas to estimate the wave beam parameters and to design the antenna are provided. The feasibility of radiating high-order modes by Vlasov antenna is also discussed and verified. The hermetization of the Vlasov antenna is researched and the results show that with such kinds of hermetization the antenna can work under gigawatt level. The design of the mode converter from TEM to TMoi is studied, which is useful when the TEM coaxial mode is radiated by Vlasov antenna. At last, the flared-end Vlasov antenna is also discussed.
在Vlasov天线方面:用矢量绕射理论建立了天线辐射场的计算模型并编写了计算程序,该程序计算结果在主瓣上与实验测量吻合良好,近旁瓣也基本一致;利用矩量法计算了天线的反射系数,表明该天线有较小的反射,总的能量反射小于0.25%;详细分析了天线的辐射特性,给出了天线辐射波束相关参数的估算公式和天线设计公式;进一步研究和论证了Vlasov天线辐射高阶轴对称模的可行性;对天线的密封方式和功率容量进行了讨论,结果表明在不需很大密封罩的情况下可以获得GW级的功率容量;为了用Vlasov天线辐射同轴TEM模,研究了TEM-TM_(01)模式转换器的设计,得到了一些基本规律;最后,介绍和分析了带有锥形喇叭的Vlasov天线。

The paper consists of five parts. Firstly I carry on a review to the domestic and foreign scholars" research on the stock price manipulation, in the second part, the paper takes an objective analysis of the way in which china"s stock market is manipulated and the cause of the manipulation. In the third chapter, firstly I find that auto-correlation of time series of stock return and persistency of the GARCH model could be an index for speculative price by comparing the characters between the speculative price and non-speculative price presented by GARCH modeling, and then stick out that low β coefficient is an important symbol of stock price manipulation through empirical study.
本文的研究分五个部分,首先对国内外学者对股价操纵方面的理论和研究成果进行了回顾,在第二部分中结合中国股市的实际情况对中国股票市场的操纵手法及形成的原因进行了客观的分析,第三章首先通过比较非操纵价格与被操纵价格的时间序列GARCH模型的特点,证明被操纵价格存在序列相关,时变条件方差不稳定的特点,然后通过实证研究表明低贝塔系数是市场操纵过程中股价异动的重要标志。
