如果您用三角形的角度進行測試，那麼可能的類型是直角、銳角、鈍角或等角三角形。In order to make up the deficiency, the science workshop datalogger made in the u. s pasco company has been used in this dissertation. the advantage of the datalogger has been extruded by the research of experiments for verification, inquiring experiments and application experiments which worked in the catalogue of the new physics courses for teaching. as a result, a fine acuity perceptional and observational ability of student will be developed, a cognitive framework will be improved, the space for investigative learning will be enlarged, multiple intelligences will be optimized and brain memory structures will be consolidated if the datalogger has been used in teaching physics experiments
數據採集器作為一種現代化設備運用於物理實驗教學，國外的研究資料已證明具有巨大的優勢，而國內才開始起步還沒有形成一個系統，為了彌補不足，本文採用美國pasco公司生產的scienceworkshop數據採集器系統設計實驗，從教學角度出發並配合物理新課程的總目標，分別從驗證性實驗、探究性實驗、應用性實驗三方面設計實驗，突出了數據採集器的優勢：即培養學生精細敏銳的感知和觀察能力，改善學生的認知結構，拓寬學生探究性學習的空間，優化學生的多元智力和強化學生的大腦記憶結構。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） 。In the bottom left of venus, saturn is beautiful, right and venus is 14 yuan, venus, saturn, a yuan 14 rows acute triangle
在金星的左下方，是美麗的土星，在金星右上方是軒轅十四，金星、土星、軒轅十四排列成一個銳角三角形。At last, this paper has developed a demo system to verify this algorithm. the results from experiment show that the simplified - model by the algorithm of divisional envelope pitches can preserve the sharp features and be of a higher resemblance with its original geometric model
實驗結果表明，採用本文提出的這種演算法來簡化三角形網格模型，簡化后的模型能很好地保留原始模型表面的尖銳特徵，與原始幾何模型有著很高的相似度，具有較高的簡化效率和時間效率。分享友人
