摘要：Modal analysis and seismic response analysis were carried out for the equatorial diagnostic port plug of international thermonuclear experimental reactor (ITER). The aim of the theoretical analysis is to verify structural strength and reliability of the device. The working condition includes one-dimensional seismic wave and two-dimensional seismic wave. Modal analysis of the device shows that primary vibration is inclined to occur in low-order modes. The horizontal (X-direction, Y-direction) maximum vibration appears at the first and the fourth eigen modes, with the natural frequency of 70.59 and 215.88 Hz respectively, and the vertical (Z-direction) primary vibration appears at the second eigen mode with the natural frequency of 82.85 Hz. According to the results of the finite element analysis (FEA) program, the weak portions of the device are distributed in the joint of port body with blanket shielding module (BSM) and inner side wall of ribbed plate for lifting flange, the maximum von Mises stress is 14.8 MPa with the Y-direction seismic wave. In accordance with the design criteria, the destructive effect is far below the failure boundary, and the structural reliability of the equatorial diagnostic port plug can meet the requirements of the design specifications.

摘要：目前,我国净水厂反冲洗水量和排泥水总量较高,越来越多的研究认为排泥水是挖掘城市水资源利用的重要组成部分。但低温低浊排泥水由于其特殊的水质特性使得对其处理回用具有挑战性。分析了低温低浊排泥水的水质特性,总结了其难处理的原因,综述了利用陶瓷膜处理技术处理低温低浊的研究进展及陶瓷膜技术的优点,对其进行评价,指出陶瓷膜技术存在的问题及未来发展趋势。

摘要：通过典型机构调查系统开展安宁疗护住院和居家服务费用分析和成本核算,结合文献评阅和专家咨询设计基本安宁疗护服务包,并参考国际经验和上海实证提出两个按服务单元付费改革方案:方案一提出住院基本安宁疗护服务包和居家服务包,并测算2020年付费标准为住院1041元/床日,居家580元/诊次;方案二提出住院基本安宁疗护服务包和居家服务包,并测算2020年付费标准为住院958元/床日,居家557元/诊次。安宁疗护采取按服务单元付费支付方式能够体现医务人员技术劳务价值,提高安宁疗护服务机构积极性,同时鼓励与引导更多机构参与安宁疗护服务,进一步促进安宁疗护融入到各级各类服务体系。
