The advent of balloon angioplasty reduced the intrusiveness for certain patients ; a balloon was fed along a catheter to the blockage, then expanded to crack and compress the plaque, leaving a wider conduit for blood flow
氣球血管造形術則降低了手術侵入程度：氣球沿著導管送進堵塞的血管區域，然後氣球會充氣，壓碎並壓緊粥狀硬化斑，以利血液流通。 -
In the second chapter, the fluid mechanics principle of vortex flowmeter at first was introduced. the classical theory about vortex flowmeter and the method of computational fluid dynamics about flow around body were expanded on, and the model of the single bluff body and the dual bluff body vortex flowmeter were constructed. and then, fvm - finite volume method - analysis software fluent was applied to analyze the flow phenomenon of flow over single bluff body or dual bluff body
然後通過大量實驗和理論分析給出雙鈍體渦街流量計的設計準則：當管徑為d ，鈍體形狀為三角形，則鈍體設計參數為：銳邊寬度= 0 . 26d ，高度= 0 . 34d ，鈍體之間的距離= 1 . 2d （即當兩鈍體寬度相等且鈍體距離等於單鈍體兩列旋渦之間的距離） 。 -

首先，本章回顧了國際貨幣制度背景，指出目前的國際貨幣制度實際上處於一種危機后並沒有得到意見統一的狀態，無規則的國際貨幣制度將長期延續下去；然後，本章對國際投機資本的范疇進行了定義，並相應指出，從20世紀70年代初期以來，國際投機資本的規模是急劇膨脹的，並且在20世紀90年代，國際投機資本還出現了組織形式機構化和操作工具衍生化的新特徵。 -
The flow through the throat - type energy dissipator and the right - angle energy dissipator are calculated by using the two - equation turbulence model, which is expansively used to simulate the flow field successfully. the principal content and the achievement are concluded as follow : as a kind of internal energy dissipator in which the turbulent flow is contracted and expanded abruptly, throat - type energy dissipator was regarded as one of the potential energy dissipator for its many advantages, such as stable flow pattern, simple structure, easily controllable flow parameter, and anti - cavitation property
結合實體試驗，利用k -模型對當今尚處于起步階段的新型消能方式?洞塞消能工和直彎消能工進行了數值模擬研究，主要內容和研究成果如下： 1洞塞消能作為一種突縮突擴式的內流消能工，具有流態穩定、結構簡單、水流參數易於控制及防空化性能等優點，是一種很有發展潛力的消能方式。 -
Taking account of those problems, the author imported uml into the description of work flow and expanded it according to its features, and also put forward the idea of work flow modeling of super activity graph based on the uml activity graph. this idea not only had the features and advantages of the uml activity graph, but also improved the descriptive ability of complicated control condition to make it more suitable for work flow modeling, allowing for the influence of outside accidents, temporal sequence and operation control on the work flow operation path
針對以上問題，作者將uml引入工作流模型描述，並針對工作流的特點對其進行擴展，提出了基於uml活動圖的活動超圖的工作流建模思想，這種思想不僅具有uml活動圖的特徵和優點，還著重考慮了外部事件、時序以及運算控制對工作流運行路徑的影響，提高了復雜控制條件的描述能力，使其更適合工作流建模。
