尾部形狀 的英文怎麼說
中文拼音 [wěibùxíngzhuàng]
尾部形狀
英文
afterbody shape-
After molting three times, the zoea enter the mysis stage during which they begin to look more like adult shrimp and swim in a characteristic fashion with head and tail pointed downwards at right angles and occasionally performing a sudden retrograde jumping action. this is known as the inversion state, the fry being suspended upside - down in the upper middle region of the pond water. this is, therefore, also called the " inverted suspension phase "
眼幼蟲脫第三次即進入糠蝦期幼蟲期mysis stage ，此期之體形已略成蝦之狀態，且具特有之游泳姿態，即頭部及尾部均向下，成一直角彎曲而時作向後跳躍游動，又因成倒立狀態，懸浮於水中的中上層，又叫倒吊期，此期幼蟲對外界的環境因素，如水溫鹽分等變化，比前兩期來得更具適應力，主要餌料為豐年蝦brine shrimp的幼蟲，但其他大小略同的動物性浮游生物，如橈腳類copepoda輪蟲類rotifera均可。The bottom edges of the endplates are mated to another winglike device, the lower main plane, which in turn is attached to the rear crash structure ? a carbon fibre cone bolted onto the gearbox
終板末端邊緣被設計成與另一個翼狀地設備相配合，這個翼狀設備是一個較低的平面，附著在尾部碰撞結構上? ?變速箱上面的碳纖維錐形螺釘。The effects of reynolds number, back surface of nozzle, aft - dome configuration and degree of submergence on aft - end internal flow were studied by both cold gas simulation and numerical simulation. it is showed that the separated flow is sensitive to the change of reynolds number and aft - end cavity configuration
最後，利用冷流模擬與數值模擬相結合的方法，研究了雷諾數、噴管背壁形狀、后封頭形狀和潛入深度對燃燒室尾部流場的影響，結果表明流動的分離對雷諾數和背壁區幾何邊界的變化很敏感。Impact of the shape of the hull back of amphibious vehicle on the inlet flow field of waterjet propulsion
兩棲車輛車體尾部形狀對噴水推進器進口流場的影響According to the character of outer shape of modem buses, the numerical calculations are performed from the simplest shape - cuboid by using ansys / flotran software. first, the foreside of the cuboid is modified step by step in 17 models ( this is equal to the process of modification to the foreside of a bus ). second, the afterbody of the cuboid is modified step by step in 9 models to model flow wake at rear end and get the drag coefficients and lift coefficients in different aterbodies
在本文中，應用ansys flofan軟體，根據現代客車外形的特點，從最簡單的長方體開始進行數值模擬計算，首先對長方體的前部進行逐步改造（相當于對一個客車頭部進行改造的過程） ，這一步驟包括了17個模型；然後再對其尾部進行變化，以模擬客車后車體形狀對空氣阻力系數的影響，該步驟包括9個模型：最後給出兩種現代客車的數值模擬結果。These rules consist of the total fit, the mathematics and fatigue physics, and the safety in tail predictions. an analysis of the test s - n data of 16mn steel weld joints reveals that the four models are reasonable if only considering the total fit as the conventional method did. but if by the present three rules, the appropriate models should be the normal or the extreme maximum value
根據先前提出的有限數據下良好假設分佈的確定方法，包括三個原則，即假設分佈形狀與誤差數據真實分佈形狀的一致性、預測的總體擬合效果、與疲勞失效機制的一致性和尾部預測的安全性，通過對線性均值s - n曲線擬合16mn鋼焊接頭s - n數據誤差的統計分析，說明應用一般推斷方法， 4種分佈都可合理地作為數據的統計模型，綜合考慮三原則后，極大值和正態分佈是可能的良好假設分佈。Abstract : based onmethods of foreign countries of using wi nd tunnel test and numerical flow simulation, optimum nose a nd tail shapes ofhigh - speed trains are studied to achieve optimum aerodynamic performance so as to efficiently reduce the influence of theaerodynamic phenome na on the train operation and the environment. research results of foreign countr ies are introduced
