摘要：Thermal performance was the most important factor in the development of borehole heat exchanger utilizing geothermal energy. The thermal performance was affected by many different design parameters, such as configuration type and borehole size of geothermal heat exchanger. These eventually determined the operation and cost efficiency of the geothermal heat exchanger system. The main purpose of this work was to assess the thermal performance of geother^nal heat exchanger with variation of borehole sizes and numbers of U-tubes inside a borehole. For this, a thermal response test rig was established with line-source theory. The thermal response test was performed with in-line variable input heat source. Effective thermal conductivity and thermal resistance were obtained from the measured data. From the measurement, the effective thermal conductivity is found to have similar values for two- pair type （4 U-tubes） and three-pair type （6 U-tubes） borehole heat exchanger systems indicating similar heat transfer ability. Meanwhile, the thermal resistance shows lower value for the three-pair type compared to the two-pair type. Measured data based resistance have lower value compared to computed result from design programs. Overall comparison finds better thermal performance for the three-pair type, however, fluctuating temperature variation indicates complex flow behavior inside the borehole and requires further study on flow characteristics.

摘要：Recently there has been great progress in laser-driven plasma-based accelerators by exploiting high-power lasers,where electron beams can be accelerated to multi-GeV energy in a centimeter-scale plasma due to the laser wakefield acceleration mechanism. While, to date, worldwide research on laser plasma accelerators has been focused on the creation of compact particle and radiation sources for basic sciences, medical and industrial applications, there is great interest in applications for high-energy physics and astrophysics, exploring unprecedented high-energy frontier phenomena. In this context, we present an overview of experimental achievements in laser plasma acceleration from the perspective of the production of GeV-level electron beams, and deduce the scaling formulas capable of predicting experimental results self-consistently, taking into account the propagation of a relativistic laser pulse through plasma and the accelerating field reduction due to beam loading. Finally, we present design examples for 10-GeV-level laser plasma acceleration, which is expected in near-term experiments by means of petawatt-class lasers.

摘要：The Philippine Arena Project is a large domed roof structure. The arena volume is significant, with 227 m x 179 m ellipse shaped space standing, which is the largest non-column arena in the world. Reinforced concrete is used for the bowl structure and main seismic resisting system is considered as dual system. For the structure above Level 04, steel rakers and columns are applied. To identify seismic resisting performance of steel structure, push over analysis had been carried out. Pre-cast concrete plank is planned for arena seating to meet constructing ability. The roof structure is grid type space frame. Tension trusses are located under the space frame for overall stability of roof structure. Wind tunnel test had been conducted to evaluate accurate wind pressure for both structure and cladding design. LRB （lead rubber bearing） is located under the roof structure to reduce seismic force delivered from sub-structure.

摘要：Recent efforts have focused on the fabrication and application of three- dimensional （3-D） nanoarchitecture electrodes, which can exhibit excellent electrochemical performance. Herein, a novel strategy towards the design and synthesis of size- and thickness-tunable two-dimensional （2-D） MnO2 nanosheets on highly conductive one-dimensional （l-D） backbone arrays has been developed via a facile, one-step enhanced chemical bath deposition （ECBD） method at a low temperature （-50 ℃）. Inclusion of an oxidizing agent, BrO3-, in the solution was crucial in controlling the heterogeneous nucleation and growth of the nanosheets, and in inducing the formation of the tailored and uniformly arranged nanosheet arrays. We fabricated supercapacitor devices based on 3-D MnO2 nanosheets with conductive Sb-doped SnO2 nanobelts as the backbone. They achieved a specific capacitance of 162 F·g-1 at an extremely high current density of 20 A·g% and good cycling stability that shows a capacitance retention of -92% of its initial value, along with a coulombic efficiency of almost 100% after 5,000 cycles in an aqueous solution of I M Na2SO4. The results were attributed to the unique hierarchical structures, which provided a short diffusion path of electrolyte ions by means of the 2-D sheets and direct electrical connections to the current collector by 1-D arrays as well as the prevention of aggregation by virtue of the well-aligned 3-D structure.

摘要：韩国的漆艺文化已有两千年以上的悠久历史，堪称已经渗入到内房和厢房等生活文化当中的代表性艺术品。目前，韩半岛上的主要生漆生产地为北韩平安北道泰川和南韩江原道原州，占整个半岛生漆产量的大部分。韩国产生漆的品质很好，生漆的主要成分漆酚（Urushiol）的含量高，酶的活度相当好，生漆涂层的干燥时间很短，硬度也很强。但是，南韩原州产高品质生漆的产量较少，价格也比日本产的贵，因此主要依靠中国进口。从史前时代至三国时代，韩国漆艺文化的主要技法是在生漆底上施以颜色绘制纹样，统一新罗时期开始变化为在生漆底上用螺钿、琥珀、青玉、金、银等宝石材料加以装饰。其后，高丽和朝鲜时代螺钿装饰成为漆器上所采用的主要技法。高丽螺钿在中国的宋朝也得到了高度评价，其卓越性被认可，直到现在高丽螺钿也被视为韩国的代表性艺术品之一。

摘要：活动教学是当代教育中重要的教学形态,它重视活动的独特价值,强调活动在学生学习过程中的重要作用。本文旨在针对新加坡的二语环境,以新加坡高中H1华文新课程之核心主题单元《家国之情》为样例,探讨一套以活动教学理论模式为依据的活动课教学流程与策略。这套活动教学流程包括了简单的外显用手操作到复杂的内隐思维活动,也包括了个人活动和群体活动,种种活动的设计都是在引导学生展开探索,让学生在趣味性、知识性的学习活动中通过亲身体验去建构发现,进而领悟和创造。论文主要介绍此主题单元之活动教学的设计与实践,并在实践教学中观察学生表现与教学成果,目的在于建设一套具有可操作性的活动教学策略,为高中语文的主题单元教学提供另一个教学选择,以有效提升教师的教学效率,并提升学生的思维能力、语文技能和人文素养。

摘要：文身是人类最古老、最普遍,也是传承和持续时间最长久的文化形态之一。传统的文身习俗具有重要的历史、艺术、社会和学术研究价值。中国是一个多民族的国家,56个民族里有文身文献记载的就达到18个以上。其中云南省现存文面遗迹中长期处在积雪冰封的文面民族独龙族显得非常神秘。
