单极的

In chapter three,we have derived a generalized dual London equation for the Abelian "electric" field A_μfrom the effective dual Abelian-Higgs model.The approximative result and the numerical simulation result as well as their figs were shown via solving the dual Abelian-Higgs model with different methods.Hereby the vortex solution of the chromo-electric field and the vortex energy density were also discussed.Finally,we have studied the dual Abelian-Higgs model with additional vacuum constant,and have unpuzzled the vacuum constant corresponding to the bag model.When the quark sources is introduced, the vacuum constant in the MIT bag model is proportional to the quartic of the monopole mass.

利用不同方法求解该方程，给出了该方程的近似结果和数值模拟结果，并分别对两种情形画出图像作了比较，据此还讨论了色电场的涡旋解及能量密度，最后讨论了含有附加真空常数的对偶阿贝尔-黑格斯模型并对应口袋模型给出了附加真空常数的物理解释，引入夸克源之后还预言麻省口袋模型中的真空常数正比于单极质量的四次方。

We also study the property of global tachyon vortex as well as monopole and in the flat spacetime, the exact solutions of them are obtained.

我们研究了整体快子弦和快子单极子的性质，得到了两者在平坦空间下的精确解，发现它们是一类非常弥散的客体，其质量主要分布在核的远处，并且它们的引力效应跟通常的拓扑缺陷也很不相同。

Though we are unable to put forward a kind of can be generally accepted by relevant different fieldsing, common statement approved for the terroristic definition in terms of law at present, We still analyse and describe the historical origin that terrorism produce in terms of France"s historiography, analyse production of it, is it attract people"s attention this line of deep historical reason of historical background and national religion of stage to develop, It is analysed that globalization causes the expanding , secessionism of gap between rich and poor and under the unilateral-polar order background, the highest doctrine of military force which U.S.A. followed has evoked other inducements, such as resistance of the weak nation, etc.

虽然我们目前无法从法律的角度给恐怖主义的定义提出一种能为有关各方面所普遍接受、共同认可的表述，我们还是从法史学的角度来分析和论述恐怖主义产生的历史根源，分析它的产生、发展到引人关注这一系列阶段的深刻的历史背景和民族宗教的历史原因，分析全球化导致贫富差距扩大、分离主义以及在单极世界秩序背景下，美国奉行的武力至上主义激起了弱国的反抗等其它诱因。

The termination of the unipolarity could be either the rise of revisionist states or the decay of the hegemony. International Relations theories must to meet the challenges posed by the unipolarity system in order to improve their theoretic interpretations, explanations, and predictions.

现今的国际体系是一个美国独霸的单极体系，美国在军事、经济、科技创新及国际制度等领域，拥有超出其他主要国家权力的主导地位，更没有面对其他国家有力的制衡，中共虽被视为美国独霸地位最可能的挑战国，不过在一定的时间内，仍未能取代美国在全球的主导性地位。

Henry Kissinger also points out that there are at least six great powers: the United States, Europe, China, Japan, Russia, and probably India in 20th century world politics. After 911 terrorist attacks in 2001, the American hegemony of unipolarity was replaced by a multipolar world. This essay attempts to analyze the contents and strategies of six great cultures. It also attempts to prove that Chinese culture and its positive defense strategy will be an important pillar for supporting the present world order. Accordingly, China's peaceful development strategy should not be a threat to its neighbors.

季辛吉所言的六大强权刚好属於上述六大文明中的五大文明（美国与欧洲同属西方文明），加上回教文明，则为六大文明，在2001年「911」恐怖攻击事件后，美国独霸全球的「单极」时代将会被「多极」所取代，21世纪全球政治的格局，将是朝「多极并立」发展，本文即在分析当前六大文明的内涵与其战略思想，证明以天道、人道、中道、王道为内涵的中国文明，与传统中国「积极防御」的国家战略，将是维系21世纪秩序的主要支柱，而中共的「和平发展」也不会对周边国家造成威胁。

These antennas can cover GSM900/DCS/PCS/UMTS operation. In the chapter 2, the antenna is designed based on the concept of monopole antenna. Furthermore, the antenna structure have two radiant paths and coupled each other at tail end to do impedance matching. In addition, to raise distance between radiation plane and ground will avoid capacitative effect effectually. In the chapter 3, the antenna is designed based on the concept of planar inverted-F antenna. Furthermore, that the antenna structure have two radiant paths and coupled each other at tail end to do impedance matching is similar to chapter 2. But there is a difference in them. We can choose the short position to change input impedance at this structure. In the chapter 4, the antenna is designed based on the concept of planar inverted-F antenna which takes coupled-fed. It will produce the first mode and high-order mode near the frequency, 900MHz. The feature of this type is to reduce the volume effectually. This antenna can not only cover GSM900/DCS/PCS/UMTS operation but maintain good radiation efficiency. Finally, we will compare three antennas, and develop procedure with industrial view, and propose the prospect of the GSM/GPRS antenna in PND, as a conclusion.

在第二章中，我们使用单极天线设计概念，使用双路径架构并於末端耦合来对天线阻抗做匹配，产生涵盖GSM900/DCS/PCS/UMTS四频操作频带，并提高与接地面的辐射高度，以避免电容效应，使天线具有良好的辐射特性；在第三章中，使用倒F形天线设计概念，使用双路径架构於末端耦合，并於辐射臂上采取适当接地点电感效应作输入阻抗匹配，达成涵盖GSM900/DCS/PCS/UMTS系统的四个操作频带；在第四章中，采用倒F形架构并使用耦合馈入方式，使得长辐射金属臂在低频900 MHz附近产生共振，产生低频基频模态及高阶模态，以达成宽频及频宽涵盖GSM900/DCS/PCS/UMTS频带操作，并有效缩减使用体积；最后，分别比较此三种架构的优缺点，再加以业界角度来思考，研发产品天线的流程及思考方向，以及天线应用於可携式导航装置中未来的展望作为本论文的总结。

From April to October 2003, a total of 40 patients aged 58 to 86 years (mean: 69.3 yr) were randomized into two comparable groups; one underwent bipolar TURP and the other received monopolar TURP. Pre-operative and post-operative serum sodium concentration, hemoglobin level, resection time, blood loss and weight of specimen were evaluated.

The effective channel mobility of4H-SiC MOSFETs is increased significantly by high temperature anneals in nitric oxide.4H-SiC MOSFET with hydrogen postoxidation annealing has a lower threshold voltage of3.1V and a wide gate voltage operation range in which the inversion channel mobility is more than100cm 2 /Vs.

SiC的雪崩击穿电场是Si的十倍，因此，理论上SiC单极功率器件的导通电阻可以比Si器件的低400倍，但在6H-SiCMOS结构中，由于反型层的电子迁移率较小，沟道迁移率测量值仅为40～50cm2/Vs，远远低于6H-SiC的体迁移率400cm2/Vs眼1熏2演，限制了SiC功率MOSFET的导通电阻Ron。

The printed UWB antenna is comprised of a planar monopole radiator and the ground plane which are connected to a coaxial cable to launch RF signals. This kind of ground and antenna system is essentially an unbalanced design, where electric currents are distributed on both radiator and ground plane, and then leakage to the outer conductor of the feeding cable. The impedance matching and radiation pattern will be influenced in the low band, which are our focus. Finally, some techniques will be proposed to reduce the cable effect on the antenna performance.

进行超宽频天线量测时，吾人会利用同轴缆线连接到网路分析仪，这时的同轴缆线不只是扮演一个传输讯号的工具而已，由於单极天线的不平衡结构，对低频而言，接地回流电流会泄漏到同轴接地的导体外部，造成同轴缆线也是一个辐射体，影响到天线低频时的阻抗匹配与辐射特性，因此本论文将探讨同轴缆线对於天线一些参数的影响，并研究提出解决的办法。

The period of the post-cold-war is a time when forces of "single-pole" and "multiple-poles" compete and struggle with each other. The European Union is a regional organization of great significance in the way of European integration, with its real strength and potential strength that any behavioral subjects of international relations cant ignore and deny. China is the greatest Socialist country in the world, and her development and growth needs a stable internal environment as well as a beneficial and harmonious international environment.

&冷战&后时代是一个&单极&势力与&多极&势力较量与斗争的时代；欧盟是欧洲一体化道路上的具有里程碑意义的一个特殊的区域性组织，它所拥有的现有实力和潜在实力是任何一个国际关系行为主体都不能忽视和否认的；中国是当今世界最大的社会主义国家，她的发展与壮大不仅需要一个稳定的国内环境，更离不开一个有利而和谐的国际环境。
