逆渦流 的英文怎麼說
中文拼音 [nìguōliú]
逆渦流
英文
back eddy-
The sea was very rough in the straits, full of eddies formed by the counter currents, and the chopping waves broke her course, whilst it became very difficult to stand on deck
海峽中的水流非常急湍，到處都是逆流造成的漩渦。唐卡德爾號走得非常吃力，急促的海浪阻礙旨它的前進。如今在甲板上，很難再站穩腳步。( 6 ) as dean number is increased, the secondary flow firstly becomes symmetry and then the anticlockwise vortexes are enlarged, the contours of axial velocity and the stream function become symmetry, the secondary flow is intensified and the friction factor ratio increases
（ 6 ）增大dean數，二次流先趨于對稱而後逆時針方向的二次渦增大，軸向速度和流函數等值線趨向于對稱，摩擦系數比增大。( 5 ) as torsion is increased, the anticlockwise secondary vortexes and the negative area of the stream function increase ; the axial velocity moves anticlockwise ( annular pipe ) or clockwise ( circular pipe ) ; the friction factor ratio finally reaches the value about 1
（ 5 ）增大撓率，逆時針方向旋轉的一二次渦和流函數的負值區域增大，軸向速度最大值的位置按逆時針（環形截面）或順時針（圓截面）方向旋轉，摩擦系數比最終趨向於1 。Furthermore, the horseshoe shape vortex system occurred to the upstream of the jet exit and the layer structure of vortexes occurred to the wake of the reverse flow region downstream of the jet are also investigated
另外，觀測到射流噴口上流的馬蹄渦系以及射流逆流區下游尾跡區旋渦的層狀結構形式。In chapter 2, a new irreversible cycle model is presented for an absorption refrigerator, in which not only the irreversibilities of heat conduction and heat leakage but also the irreversibilities resulting from the friction, eddy and other irreversible effects inside the working fluid are taken into account
第二章建立了不可逆吸收式製冷循環新模型，模型不僅考慮了熱傳導和熱漏不可逆性，而且也考慮了循環工質內部由於摩擦，渦流及其它不可逆效應所引起的內不可逆性。Finite element preprocessor, eddy current electromagnetic field calculation, the postprocessor and the visualization processor were integrated together in the software system, and good graphic user interface was also offered
該系統將有限元前處理、渦流電磁場計算、滲碳層深度逆問題求解及計算結果的可視化處理結合起來，提供了良好的用戶界面。Mss adopt pairs set of transmission, make two swirl form convection, increase water power shear function, and impel the wasted paper to accelerate hydrate andpulp. meanwhile the knife is adjustable, it can increase the pulp range. in can increase the pulp range. in thecourse of operating, wasted paper in high - speed is adverse current always. it makes paper and paper produce friction each other in order to reach the breaking to pieces fast of paper and raise the efficiency
Mss採用雙套傳動、使用兩個漩渦形成對流，從而增加水利剪切作用，促使廢紙加速水化、碎解：同時，刀盤可調，可以增大碎漿范圍設備在運轉過程中，廢紙總是處在高速逆流中，從而使紙片于紙片之間互產生摩擦，以達到紙片的快速碎解，提高效率。分享友人
