Study on the Act of Perpetrating of the Crime of Theft
盗窃罪是一个历史悠远的罪名,是当今世界各国刑法重点规定的一项罪名,我国刑法自然也不例外。然而,关于盗窃罪的实行行为,我国刑法并没有予以明确。我国刑法学界关于盗窃罪实行行为的主流观点是秘密窃取,然而这种主流观点在理论上与司法实务中都存在一定的问题。所以,对盗窃罪的实行行为进行一番系统的研究十分必要。 文章分为引言、主体和结论三大部分,通过对盗窃罪的实行行为的理论分析和实践把握,最终提出完善盗窃罪实行行为的建议。主体部分分为四章。 第一章为盗窃罪实行行为之一般原理。首先就行为的一般原理进行了一番简单的梳理,随后对犯罪的实行行为进行了一番简要的分析,最后重点引出我国刑法中盗窃罪的实行行为,并简要...The theft was regarded as a crime long time ago. It is one of the most important criminal offenses in many countries criminal law around the world, our criminal law is no exception. However, with regard to the act of perpetrating of the criminal of theft, the meaning in our criminal law is not clear. The mainstream point of view of the act of perpetrating of theft is secret theft. But the view hav...学位:法学硕士院系专业:法学院法律系_刑法学学号:1292007115028
Exchange Rate Movement and Monetary Policy Rule of Emerging Market Countries——Research on Inflation Targeting Countries
通货膨胀目标制是20世纪90年代以来国际货币政策领域的一个重要发展。迄今为止已经有三十多个国家先后加入到了这一行列,而新兴市场国家俨然已成为这股潮流的主体。许多学者认为弹性汇率、通货膨胀目标制和货币政策规则构成了一个理想的货币政策体系,但新兴市场国家往往由于仍处在发展阶段,其宏观经济运行也会随着对外开放程度的不断提高而受到各种各样不确定性外部因素的影响,各国在货币政策制定和执行过程中实际上仍然可能面临着稳定通胀和稳定汇率的权衡。因此学术界对于实施通货膨胀目标制后,新兴市场国家货币政策是否应当对汇率波动作出响应这一问题并未达成一致意见。 目前国内学者关于通货膨胀目标制的研究已经比较丰富,但大多...Inflation targeting is an important development of international monetary policy since 1990s. There are more than 30 countries have adopted inflation targeting up to now, and the emerging market countries are the main part of this trend. Many researchers insisted that flexible exchange rate regime, inflation targeting and monetary policy rule make an ideal monetary policy system, while the emergin...学位:经济学博士院系专业:经济学院_世界经济学号:1572012015361

我国的房地产市场经过近二十年的蓬勃发展,已经从最初的萌芽阶段逐渐走入成熟期,开发商和消费者的素质都在不断的提高,在房地产项目开发的全过程合理地运用市场营销理论进行项目整体策划已经成为一个成功的开发商必须采用的手段,而别墅作为最高档的房地产产品,更加需要完善的营销策划。从目前厦门市场现有别墅项目的开发与经营情况来看,还没有一个能够全面运用市场营销的成功项目,因此本文希望借对厦门别墅市场的回顾与总结及消费心理研究,探讨如何根据本地市场特色开发出具有一定超前性和市场生命力并且能够满足消费者需求产品,并力争将“阳光海岸“塑造成在本省乃至全国具有较大影响力的别墅项目。本文第一、二部分综合回顾了厦门别墅市...学位:管理学硕士院系专业:管理学院企业管理系_工商管理硕士(MBA)学号:19951506
Hypersonic Inlet Design Software Development
高超声速进气道作为超燃冲压发动机的核心部件而备受关注。国内外学者对其开展了大量研究工作,形成了不同的设计理论与设计方法。本文在综合考虑高超声速进气道总体需求的基础上,总结现有高超声速进气道的设计方法开发一套高超声速进气道设计软件实现进气道的气动外形设计,并在此基础上对进气道起动问题进行了研究。具体工作如下: (1)构建新型的软件分层开发技术架构,实现对软件界面层、逻辑层和数据层的解耦。分别选取Python脚本语言和C++语言对逻辑层和数据层进行开发,并将进气道设计算法编译成DLL动态链接库供逻辑层调用,在保障软件运行效率的前提下实现对源码的高效管控和更新。 (2)分析了高超声速进气道设计软...Hypersonic inlet, as the core component of scramjet, has caused extensive con-centration these years.

巴西、南非和俄罗斯货币政策规则实证研究
本文在一个开放经济动态随机一般均衡模型框架下,对金砖国家中巴西、南非、俄罗斯的货币政策规则进行了贝叶斯估计和检验。研究结果表明:巴西和南非央行实施通货膨胀目标制以后货币政策规则对汇率波动没有明显响应;俄罗斯央行则面临稳定通胀还是稳定汇率的权衡,因此俄罗斯央行对汇率波动反应系数较大,但金融危机过后该系数有所下降,通胀反应系数则明显提高。教育部哲学社会科学研究重大课题攻关项目“要素成本上升背景下我国外贸中长期发展趋势研究”(批准号:13JZD010); 厦门大学国际经济与贸易系教育发展基金资助项目的部分研究成
A New Understanding of Hypersonic Inlets' Startability Criterion
为了判断进气道起动马赫数,基于Kantrowitz起动判据,联系激波关系式和流量连续方程得到一系列等值线,将等值线推广到有入射激波和低马赫数溢流的情况。结果表明这些等值线具有以下特性:等值线连接进气道的内收缩比和总收缩比;等值线是等总压恢复线和等流量线;等值线可由Isentropic曲线方程乘于进气道内收缩段自起动时总压恢复的倒数得到;存在入射激波的起动等值线在设计状态等值线的右侧;有低马赫数溢流的起动等值线在设计状态等值线的左侧;等值线提供了一种联系Kantrowitz和Isentropic曲线的方法。根据以上特性,将等值线应用于高超声速进气道起动问题,并通过实例应用文中的理论判据评估无粘条件下混压式多楔二元进气道来流起动马赫数理论值,与CFD结果吻合较好,误差小于2%,初步探索了理论快速估算进气道起动马赫数的可行性。A series of isolines combining total compression ratio with starting Mach number were acquired by the shock conditions and the continuity equation,based on studies of two-dimensional hypersonic inlet starting mechanism and Kantrowize criterion. These isolines have the following characteristics: The isolines provide a connection between internal compression ratio and total compression ratio. Each isoline has equivalent value of total pressure recovery and mass flow. The isolines can be easily gained by using isentropic criteria equation times the reciprocal of critical starting total pressure recovery of internal duct. The isolines move rightwards because of the incident shock wave and walk leftwards owing to the mass spillage. The isolines provide a mechanism for associating Kantrowitz with isentropic criterion. Conclusively,using these isolines rapidly estimates the inviscid starting Mach number of a two-dimensional mixed-compression multi-wedge hypersonic inlet. The prediction results are in good agreement with the CFD results. The errors are less than 2%,demonstrating the feasibility of this method.国家自然科学基金(51276151;91441128);; 国防基础科研(B1420133058);; 中央高校基本科研业务费(20720140540
Application of Reverse Bleed Slots in Internal Waverider-Derived Hypersonic Inlet
采用逆向开槽技术,对三维内乘波式高超声速进气道的低马赫数起动和抗反压能力进行研究,提出了逆向直泄流槽和逆向倒角泄流槽两种方案。数值研究结果表明:逆向泄流槽在三维内乘波式进气道自起动和抗反压过程中起到气动开关作用。进气道不起动或反压过高时,泄流槽处于开启状态;进气道起动后,泄流槽接近气动关闭状态,对进气道总体性能影响较小。两种逆向泄流槽都拓宽了三维内乘波式进气道的低马赫数起动范围,提高了进气道的抗反压能力。其中,逆向倒角泄流槽比逆向直泄流槽具有更宽的低马赫数起动范围和更强的抗反压能力。Two bleed-slot patterns were applied to the internal waverider-derived hypersonic inlet.Both of them consisted of two parallel slots and reverse to the incoming flow direction.The geometric shapes of the two slot patterns were similar except for the curved chamfer on the slot surface near the inlet wall.Numerical simulations were carried out to examine the influence of bleeding systems on the inlet performance.The results show that reverse bleed slots behave independently on the inlet flow status.When the inlet is un-started or the back-pressure is too high, the bleeding slots are fully opened to receive more spillage.On the other hand, the slots are aerodynamically self-adapted to be closed once the inlet is started, which results in a little effect on the inlet performance.Both straight and chamfered reverse bleed slots can lower the starting Mach number, and increase the back-pressure resistance of the internal waverider-derived hypersonic inlet.In particular, the chamfered slots have a better performance than the straight one regarding the capability of back-pressure resistance.国家自然科学基金(51006051
