Primary Study on VOCs Released by Michelia skinneriana and Volatile Signaling in Plant-Plant Interaction

本课题主要研究了野含笑的三种处理（健康树、近对照及虫害树）释放的VOCs成分及VOCs调控的野含笑种群间的信号传递。结果发现：三种处理野含笑释放的VOCs都是包含很多种成分的复杂混合气体。健康野含笑释放的VOCs（13：00-15：00）TCT-GC-MS分析后共分出73个峰，其中相对含量0.05%以上的成分38种，占VOCs总含量的82.14%，含量较大的成分包括2-甲基-1-丙醇、2-甲基-丙酸乙酯、己烷等。与含笑属其他种VOCs成分相比，野含笑VOCs中临苯二甲酸二甲酯、顺式-1-甲氧基-1-丁烯、乙酸-（z）-2-戊烯酯为首次报道。虫害野含笑VOCs（13：00-15：00）中相对含量...In this paper, Michelia skinneriana plants were labled into three types: healthy, near-contrastive and insect-damaged.

Research on Performance Optimization for SSD-Based Storage Systems

数据量的激增给计算机存储系统带来严峻的性能挑战。固态盘作为新型存储介质，已被企业级存储系统和数据中心广泛使用，但简单地将传统存储软件应用于固态盘将带来一些新的问题，如将磁盘阵列技术应用于固态盘会加剧固态盘的垃圾回收操作所引发的性能波动性问题，将传统键值（KeyValue，简称KV）存储系统部署于固态盘上也可能造成存储效率低下等问题。本文分别以黑盒和白盒的使用角度，分别对固态盘阵列和基于固态盘的KV存储系统进行研究。 首先，对固态盘阵列的最优分块大小进行研究，理论分析和真实设备的性能测试结果表明，固态盘阵列的分块大小会对固态盘阵列的读写性能产生较大影响。基于分块大小与真实应用负载的读写密集特性...With rapidly increasing of data, computer storage systems encounter serious performance challenge. As new storage media, Solid State Drives (short for SSDs), have been widely used in enterprise storage systems and data centers. However, simply applying traditional storage software to SSDs will bring some new problems, such as the performance variability issue caused by Garbage Collection (short fo...学位：工学硕士院系专业：信息科学与技术学院_计算机科学与技术学号：2302014115316

The Study on Judicial Proof of Affirmative Defense

“积极辩护事由”这个术语源于美国，美国刑法中的积极辩护事由是指辩方在庭审中所提出的法定的或者被告人独知的正当理由、免责事由或其他事由。它的提出能够形成新的事实争点，一旦成立便可以使被告人无罪或者在某种程度上减轻罪行。在美国，辩方需要对积极辩护事由承担一定的证明责任。我国立法中虽然没有出现过“积极辩护事由”这个术语，但司法实践中却存在与之非常相似的辩护事由，如正当防卫、不在犯罪现场、排除非法证据等。这类辩护事由被提出后，关于这类辩护事由的司法证明活动是如何展开的，我国理论界争议很大，现有立法也没有给出一套完整的模式，故司法实践中这类辩护事由的司法证明活动各式各样，没有统一标准。这既不利于案件事实...Originated in the US, “Affirmative Defense” in American Law refers to the defense of the defender in the trial by the legal or the defendant's original reasons, exemption or other reasons for the content and the ability to form a new factual point of defense. Once this defense turns successful, it can make the defendant innocent or to some extent reduce the crime. In the US the defender needs to...学位：法学硕士院系专业：法学院_诉讼法学学号：1362014115020

《台湾外志五虎传》考证

《台湾外志五虎传》一书演绎明末清初闽台史事,体近小说,率多不经之语,是以学者多不注意。通过考证,我们发现该书并非个人创作型的章回体小说,而属于胡适先生所谓的历史演进型作品,和《西游记》《水浒传》等传世经典当属同类。民间传说\"漳州五虎将\"是《台湾外志五虎传》的主体,部分内容或可补史传之阙。而比较该书另外一个重要来源江日昇《台湾外记》,则又为我们展现了部分明清史料的演进线索

Optimal windbreak design for wind-erosion in high-speed railway

It is also very important to improve resistant capabilities of wind resistance and structural stability of the windbreak while reducing train aerodynamic load. This article proposes a new type of windbreak with double-layer structure forming a cavity chamber with hole for energy dissipation of crosswind. Numerical simulation was used to analysis the wind protection effect of two kinds of windbreak and their own wind-resistance performance. The results showed that the two types of windbreaks can significantly reduce the train aerodynamic load under the action of crosswind, and the force act on the windbreak with cavity chamber structure is small than on another one with single layer structure. The new windbreak has better effect in aerodynamic load shedding for the train, stronger resistant capabilities of wind resistance and safety of structure. This new windbreak with cavity chamber will provides useful references for design of the wind protection system for high speed train. © 2013 Taylor & Francis Group

Transonic Aeroelastic Numerical Simulation in Aeronautical Engineering

A lower-upper symmetric Gauss-Seidel (LU-SGS) subiteration scheme is constructed for time-marching of the fluid equations. The Harten-Lax-van Leer-Einfeldt-Wada (HLLEW) scheme is used for the spatial discretization. The same subiteration formulation is applied directly to the structural equations of motion in generalized coordinates. Through subiteration between the fluid and structural equations, a fully implicit aeroelastic solver is obtained for the numerical simulation of fluid/structure interaction. To improve the ability for application to complex configurations, a multiblock grid is used for the flow field calculation and transfinite interpolation (TFI) is employed for the adaptive moving grid deformation. The infinite plate spline (IPS) and the principal of virtual work are utilized for the data transformation between the fluid and structure. The developed code was first validated through the comparison of experimental and computational results for the AGARD 445.6 standard aeroelastic wing. Then, the flutter character of a tail wing with control surface was analyzed. Finally, flutter boundaries of a complex aircraft configuration were predicted

An Empirical Study on Correlations among Asset Returns

马科维茨的资产组合理论表明，投资者通过在多种资产之间进行分散化投资，可以降低整个投资组合的风险。对于整个投资组合的风险大小而言，除了与投资组合中包含的资产数量有关外，构成投资组合的各种资产收益之间的相关性对整个投资组合的风险大小有着非常重要的影响。只有尽量分散化投资于相关性较低的资产，才能尽可能地降低整个投资组合的风险，此时投资者从分散化投资中获得的好处才比较大。因此，资产收益之间的相关性对于投资者的分散化与资产配置决策以及风险管理有着重要的影响。在构造投资组合时，通常总是隐含着资产收益之间的相关性为常数这一假定。然而，近年来的实证研究表明各种证券收益的波动率是时变的。那么，假定资产收益之间的...Markowitz’s portfolio theory has suggested that by diversifying among various assets, investors can reduce the risk of whole portfolio. Besides the quantity of assets included in the portfolio has relation to the risk of whole portfolio, the correlations among assets consisting the portfolio also have an important influence on the risk of whole portfolio.
