Finally, with Tobin's "Separation Theorem", we introduce the transaction cost into the efficient frontier and t he effective efficient frontier is obtained. And a quadratic utility function is applied to demonstrate that maintaining a suitable level of transaction cost in the current Chinese stock market is important to the equilibrium of the Chinese stock market and the risk control of the individual asset.

本文的第四部分，引用托宾的"分离定理"，通过加入交易成本，区分了名义有效边界和实际有效边界，指出了交易成本调整对我国股票市场均衡影响的作用机制，并引入了效用函数，实证研究了交易成本适度对我国股票市场均衡和个人资产风险水平控制的重要意义。

We conclude that the two-funds strong separation theorem holds and that the mean-variance efficient frontier is a straight line in standard deviation-expected return space under given partial information whether short selling is allowed or not.

综合考擦卖空机制和部分信息情况，我们得到结论：在确定部分信息下，无论是否允许股票卖空，二基金强分离，均值一方差有效前沿在均值一标准差空间是一条直线。

The main content of this dissertation includes: 1. Research on the theory of ultrasonic power supply, introduce its development process. On the basis of these, fix on the scheme of medical ultrasonic low-power supply. 2. According to the principle of modularized design, divide medical ultrasonic low-power supply into four parts. They are power amplify circuit, power control circuit, frequency automatic tracking circuit and matching circuit. Separately research on their theories and design their circuits and necessary programs, especially, effectively resolve the problem tracking the supersonic vibration system with a narrow syntony frequency bandwidth and a high swing. 3. The matching experiments gain good result, and prove that medical ultrasonic low-power supply is entirely up to the mustard on intellectualization, wide band of working frequency, steady output and high efficiency.

本文工作的主要内容包括： 1、研究了超声功率电源的原理，并回顾了它的发展过程，在此基础之上确定本文医用小功率超声电源的设计方案； 2、按照模块化的设计原则，将医用小功率超声电源的设计分解为功率放大电路、功率控制电路、频率自动跟踪电路和匹配电路等四个部分，分别研究了各部分的原理，在此基础之上进行了具体的电路设计和程序设计，尤其是有效地解决了对谐振频率带宽窄振幅高的超声振动系统的频率跟踪问题； 3、通过与超声振动系统的各项配合实验，取得了很好的实验结果，验证了医用小功率超声电源完全满足智能化、工作频带宽、输出功率稳定、输出效率高的设计要求。

From the tests,we have obtained some structural variant features related with salt resistance and demonstrated the successful introduction of Rhizophora apicularta DNA into tomato.This thesis contains two parts. In the first part,the morphological and anatomical structures of the leaves were investigated. As to the morphology,some difference between control and transformed tomato were found. The leaf dimensions of the transformed tomato with unextended leaves were smaller than that of control. These structure changes should help to decrease the evaporation of water effectively and release the physiological drought resulted from saline.

本实验分两部分：第一部分、对转化番茄的形态及细胞显微结构进行观察与分析，实验表明转化番茄形态与对照相比有明显的变化，其叶面积变小，叶形收拢，这种结构可有效地减少水分的蒸发，缓解由盐胁产生的生理干旱；组织解剖结构结果显示，耐盐番茄在细胞结构上发生了明显的变异：其气孔器倾向下陷，表皮毛增多，叶脉微管组织不发达，微管束周围出现增多的贮水细胞，叶缘及其它部位表面分化出大型的多细胞分泌型结构，这些结构与转化番茄后代较强的耐盐能力有关。

Section three, entitled the criminal policy of combining punishment with leniency and improvement of procedural law, puts forward, under the guidance of our countrys criminal policy which emphasizes crime control, the difficulties in carrying out, in criminal procedure law, the function of protecting human rights, the vainness of the limited regulations of rights in prodecural law under the guidance of basic criminal policy, and the nominal state of procedural law.

通过这些方面的完善，让刑事实体法更好的体现宽严相济的刑事政策。第三部分题为宽严相济刑事政策对我国刑事程序法的指导。该部分提出在我国一贯重犯罪控制的刑事政策的指导下，刑事诉讼法中人权保护的空间难以有效打开，许多基本刑事政策使程序法中有限的权利规则处于虚置状态，使程序法名存实亡。
