摘要通過數值計算發現：將拋物線繞通過焦點的非拋物線對稱軸旋轉而形成的賦形拋物面天線可產生環狀的方向圖主瓣（此主瓣指的是主瓣最大值處） 。In order to further optimize structure of the valve, the design need engineering analysis, and need feedback information of performance parameter in experiment to modify design. because of limited time, this paper establishes stress distribution and deform only by fea, and optimizes the structure of valve. it can ensure the valve meet the requirement of fact usage and assembly, and found good base for further research and experiment on body or out - of body and manufacture on large scale
為了進一步對瓣環和瓣葉作結構優化，設計還需要進行工程分析，還需要將實驗獲取的性能參數信息反饋回來，修改設計，由於時間關系本論文僅用有限元分析確定人工心瓣在工作及裝配時的應力分佈和變形情況，對瓣環和瓣葉的結構進行優化，以確保設計出來的人工心瓣滿足實際使用和裝配要求，為人工心瓣的進一步研究、進行離體和在體實驗及批量生產奠定良好的基礎。Objectives : the purposes of the present study are as follows : ( 1 ) anatomical study inclulding observation and measurement on arterial, especially venous system of flap was performed to attempt to illuminate the regular patterns of the distribution of the arteries, veins and their branches in the axial vascular skin flap. ( 2 ) fathoming the origination, distribution, drainage scope and communicating path of deep and superficial veins or accompanied and unaccompanied veins. ( 3 ) elucidating the positions, shape and functions of venous valves in deep and superficial venous stem and its communicating branches, observing their affects on the venous blood circulation
