So far the software , developed by george mylonas at imperial , has only been tested on an artificial heart using a robotic arm 到目前为止，这种软件只通过一个机械手臂在一个人造心脏上进行过试验。
This work is being conducted by francesco migneco , m . d . , a research fellow with the artificial heart laboratory 一旦我们理解实验室中如何制造这些模型，我们将能够制造一个完整的生物医学工程心脏。 ”
Principle : to take enous blood in io out of body , and reinfuse to patients ' artery or enous system by artificial heart and lung bypass oxygenation to partly replace heart and lung function 19原理：将体内的静脉血引出体外，经过人工心肺旁路氧合重新注入病人动脉或静脉系统，起到心肺部分替代作用
The thesis is about the design and manufacture of a new type of artificial heart valve . it can be divided into three main parts : construction of the artificial heart valve design , manufacture and assembly process 本论文的内容是关于一种新型的双叶人工心脏瓣膜的设计与制造，可划分为三个主要部分：人工心瓣的结构设计，制造及装配工艺。
In recent years , the research of the artificial heart has become the attentive focus of heart surgery and biomedical engineering field , but the expensive cost of machining and experiment hold - s up the development of artificial heart technology 摘要近年来，血泵的研究已成为心脏外科和生物医学工程领域关注的焦点，但昂贵的加工及实验成本阻碍了血泵技术的发展。
The product drawings and processes are tested . the good of the thesis is reached . the thesis form an excellent base of the series design , production and research of the artificial heart valve 完成的心脏瓣膜产品图纸、工艺和工艺装备，经试制过程考核验证，是正确的和可行的，达到了论文工作的预期目标，所作的探索，为人工心瓣的系列化设计，批量生产以及进一步研究奠定了良好的基础。
This thesis is about the design and engineering analysis of a new type of bileaflet artificial heart valve . it can be divided into three main parts : theoretical calculation of the valve , computer aided design , engineering analysis 本论文的内容是关于一种新型的双叶型人工心脏瓣膜的设计与工程分析，可以划分为三个主要部分：人工心瓣的结构理论计算、计算机辅助设计以及计算机辅助工程分析。
The magnetic suspension bearingless motors generate both electromagnetic torque and magnetic levitation forces for the rotor suspension by the motor itself . the bearingless motor is comparatively suited for using as artificial heart blood pump motor due to the advantages of without mechanical wear and noise , structure compact and contactless 磁悬浮无轴承电机定、转子既用于产生驱动力矩，同时又用于产生支撑转子的磁悬浮力，具有无机械磨损、噪音小、可高转速和体积小等特点，比较适用于人工心脏血泵电机。
This paper introduces the definition and characteristics of virtual prototyping , and through the development of artificial heart technology and our researches , it also proves that the application ov virtual prototyping in micro axial blood pump can greatly reduce the product cost , shorten the production period , push forward the clinical application of artificial heart , and have a very bright future 本文简要介绍了虚拟样机技术的定义及特点，并结合人工心脏技术的发展和笔者所在课题组的研究工作，说明虚拟样机技术在微型轴流血泵设计中的应用可以大大节省产品开发费用，缩短产品研究周期，推进血泵进入临床应用的进程，具有广泛的发展前景。
This study is based on the analyses of a series of different types of artificial heart valve in home and abroad . to overcome the shortcoming of existed artificial heart valve , several forms of bileaflet mechanical heart valve are developed . after a thorough comparison and analysis of the characters of these forms , some ideal structures are selected to be manufactured 本文的研究工作是对国内外诸多瓣膜产品进行深入分析研究的基础上开展的，为了克服人工心脏瓣膜存在的各种弊端，本文提出了三种结构形式的双叶瓣，并就各种结构形式的特点进行分析比较。
