Medical equipment provides images, physiological results or other schematics of the patients to help doctors deal with the routines. It is also the major tool to the lab assistant in the clinical teaching and studies. It becomes one of a symbol of the technological level in modern hospital. The director of the hospital should establish an effi cacious management pattern to manage the medical equipment, so that it will be operated in good condition to insure the safety of the patients. Since the maintenance is an important part of medical equipment management, it is significant that the hospital should establish a system to fit for itself. The study reviews the issues in hospital medical equipment maintenance management, the development of the maintenance management model and the characteristics, as well as the status at home and abroad. The research has been fi nished by using literature research method, questionnaire survey method and data analysis method. Then we analyze the current status of hospital medical equipment maintenance management model to fi nd the problems. Based on the authentic and effective data from the survey, we can deduce the overview about the maintenance model in Beijing. The paper discusses the advantages and the disadvantages between the different model, and it makes suggestions on the follow aspects, such as system management, quality management, personnel management, cost management, information management perspective.展开更多
为满足船东对MAN低速主机配置、机舱布置和船舶经济性的要求,分别对基于选择催化还原(Selective Catalytic Reduction,SCR)技术和废气再循环(Exhaust Gas Recirculation,EGR)技术的2种MAN低速主机配置方案的设计原理及辅助系统设计进行...为满足船东对MAN低速主机配置、机舱布置和船舶经济性的要求,分别对基于选择催化还原(Selective Catalytic Reduction,SCR)技术和废气再循环(Exhaust Gas Recirculation,EGR)技术的2种MAN低速主机配置方案的设计原理及辅助系统设计进行分析。从燃油、化学品消耗和机舱布置方面进行研究,为船东基于安装和运行成本考虑选择合适的减排技术方案提供参考。实例对比分析结果表明,虽然SCR配置方案的机舱布置相对困难,但目前其设备和燃油成本低于EGR配置方案,具有更好的经济性。随着燃油和设备价格的不断调整,可综合对比2种配置方案的经济性之后选择更优的方案。展开更多
