摘要：Ion cyclotron wave resonance heating(ICRH) is one of the most important auxiliary methods to heat plasma in the Experimental Advanced Superconducting Tokamak(EAST). Several megawatts of power is transmitted through separate coaxial lines and coupled with the plasma through arrays of loop antennas. The parameters of the ICRH system, including the injected power and phasing between antenna straps, are critical to the coupling efficiency of the power as well as the resulting impact on the heating efficiency. In this paper, we present a system for feedback control of the phase between the current straps and the ICRH power on EAST. The feedback control system was tested using both a matched dummy load and a plasma load, and it successfully maintained stable operation in the 2016 EAST campaign. Good control of the injected power and wave phases was achieved during edgelocalized mode operation.

摘要：正确把握文化产业发展中政府、企业、园区之间各自的角色、关系以及各自应该发挥的作用,是文化产业真正发展成为国民经济支柱产业的必要前提。历史表明,在全球文化产业发展历程中,政府在制定国家战略和发展计划,充分利用各种机会、资源和力量,为文化企业提供各种服务,以及在推介宣传、整合资源等方面对文化企业给予帮助这四个方面扮演了重要角色。我国文化产业发展起步较晚,政府必须通过政策引导带动全社会关注和兴办文化企业,为文化产业的发展营造良好环境。要做强做大,关键在于改革和创新,增强自身的活力和造血功能,培育一批文化产业的"龙头"和"旗舰"。文化创意能够激活文化资源、激发文化生产力、增强文化企业发展活力,提升区域文化竞争力和文化软实力。而文化产业园区的重要作用则主要表现在集聚生产要素、优化资源配置、加快制度创新、延伸产业链等方面。江苏的文化产业发展正处在初始阶段,当前最重要的是通过政府提倡和政策引导带动全社会关注、支持、兴办文化企业。同时,政府必须给予全方位的服务,为文化产业的发展营造良好环境。目前江苏文化产业的发展环境和制度建设主要包括把文化产业发展列入发展战略,进一步深化文化体制改革,培育壮大文化产业主体,加强文化产业集聚区建设,大力发展文化市场体系,构建政策、信息、博览交易会、人才培养等服务平台等等六项措施。

摘要：当代经济、社会和文化经历了快速的发展,在全球文化一体化和区域化共同发展、相互交织的情况下,艺术工作的时代特征已较过去发生了巨大变化,艺术工作所承担的社会功能日趋复杂,新中国所坚守的艺术工作的方针、原则,在当代也做出了相应调整,当前艺术工作的任务和措施也都因时而变。江苏全省的艺术事业近年来经过不断探索和努力实践,已得到长足的发展,艺术创作的题材、形式、制作以及艺术人才培养等诸方面初步繁荣,并已获得一些宝贵经验。在当前文化体制改革的大背景下,突出艺术精品创作的重点、继续增加各级政府投入、积极探索创新机制、多方面拓宽市场渠道、努力培养艺术人才,已成为支撑文化事业快速发展的重要举措,同时,影响艺术工作能否得以繁荣发展的关键仍然是对和谐共进的良好艺术氛围的营造力度,而这一切都基础于为艺术人才的成长所提供的良好制度保障的具体措施和艺术所依赖的符合自身发展规律的良好生态环境的创造。

摘要：In view of the limitations of solid metal heat sink in the heat dissipation of high power light emitting diode （LED）, a kind of miniaturized phase change heat sink is developed for high power LED packaging. First, the fabrication process of miniaturized phase change heat sink is investigated, upon which all parts of the heat sink are fabricated including main-body and end-cover of the heat sink, the formation of three-dimensional boiling structures at the evaporation end, the sintering of the wick, and the encapsulation of high power LED phase change heat sink. Subsequently, with the assistance of the developed testing system, heat transfer performance of the heat sink is tested under the condition of natural convection, upon which the influence of thermal load and working medium on the heat transfer performance is investigated. Finally, the heat transfer performance of the developed miniaturized phase change heat sink is compared with that of metal solid heat sink. Results show that the developed miniaturized phase change heat sink presents much better heat transfer performance over traditional metal solid heat sink, and is suitable for the packaging of high power LED.
