In this paper, a cryosurgery-hyperthermia system is proposed for taking advantage of the alternated cooling and heating treatment in tumor. A novel control system is proposed to ensure that the thermal system works effectively. Firstly,the tissue temperature around the probe is regulated and kept in a desired range when radio frequency ablation is operated. Secondly, precise control of temperature is achieved in hyperthermia treatment using fuzzy logic PID type controller. The results of ex vivo liver experiment demonstrate that this system could provide a rather good performance with the proposed control method.

"场馆化"是奥运会组委会根据总体工作计划的安排和实际筹办工作的需要,将奥运会筹办工作重心从以各职能部门运行管理为主逐步转变为以各竞赛场馆运行管理为中心的组织运行演变过程。都灵奥组委的组织结构也因"场馆化"的要求而变革,变革后的组织结构更好的满足了各部门以场馆工作为主线开展部门工作的需要。北京奥组委应吸取都灵奥组委组织结构"场馆化"的经验,探索"场馆化"的运行模式,为胜利举办奥运会打下组织基础。

为了实现易于集成到高强度聚焦超声(HIFU)系统中的驱动功率监测技术,通过监测驱动功率间接监测声功率,进而确保热消融的有效性和安全性,采用C5948双定向耦合器与AD8363均方根功率检波器,搭建驱动功率在线监测装置.该装置包括功率耦合单元、功率检测单元和数据采集单元.使用电压峰峰值为20~200mV的不同频率的信号源,将该装置接入HIFU系统并测量入射功率、反射功率及实际加载功率.HIFU系统的现有功率监测方法主要有2种,即测量HIFU换能器电压、电流及其相位差和使用商用功率计,将这2种方法与所提出装置进行对比.结果表明使用本装置测量入射功率和反射功率的误差低于10%,实际加载功率的测量误差低于5%,且误差来源于耦合器的方向性.

"两山一水"生态旅游圈的开发对南水北调中线工程的可持续发展有重要意义。运用文献综合法、SWOT分析法,对南水北调中线水源地丹江口水库、伏牛山、武当山(两山一水)及其周边旅游地的生态旅游资源进行综合分析。分析发现,建设该旅游圈具有明显的地缘和区位优势,同时旅游圈的生态旅游资源不但丰富,而且优势互补,特色鲜明,基础良好,极具发展潜力;劣势在于区域经济发展落后,跨区域发展协调难度大。但是,国家对水源区发展生态旅游的政策支持,不断建设的交通网为本旅游圈建设提供了难得的机遇。为此,提出发展该生态旅游圈一体化、点-环-圈、整体联合促销的发展战略,设计了6类旅游产品21条旅游线路,并针对开发的劣势和挑战提出:政府要积极发挥在生态旅游圈建设中的推动作用,培育区域旅游产业联盟,合理定位市场,联合宣传促销,开发特色产品,建立区域品牌优势等建议.
