typical a. 典型的 macroscopic scale 宏觀尺度 packets of fluid 流體小包 turbulence viscosity 湍流粘性 eddy viscosity 渦粘性 as a consequence 作為結(jié)果 growth rate 增長率 separation of flow 流動分離 immensely ad. 無限地, 廣大地, 龐大地 (Pressure gradient is one of the factors that influences a flow immensely.) retarding effect upon the flow 對流動的阻滯減速作用 favourable pressure gradient (negative pressure gradient) 順壓梯度 adverse pressure gradient (positive pressure gradient) 逆壓梯度 to separate the flow 使流動分離 counteract vt. 抵消; 阻礙; 中和; 使受挫 from this point onwards 從這點往后 reverse 倒流 （.The flow reverses.） recirculating flow 回流 contour of the body 物體的外輪廓 point of separation 分離點 terminate v. 終止 reattach v. 再附（著） separation bubble 分離氣泡 drag 阻力 skin friction drag 表面摩擦阻力 pressure drag or form drag 壓差阻力(形阻) (Example sentences: There is another agent that can cause drag. This is the pressure difference upon the flow. This could come about due to geometrical effects that induce separation as happens with a cylinder to be discussed later. This is called Pressure Drag or Form Drag, since it is due to the body geometry. The sum of pressure drag and skin friction drag constitutes Drag about the body or Profile Drag.） prone[pr.un] a. ①易于…的, 有…傾向的(to) ②俯伏的, 面向下的 ③傾斜的, 陡的 (.be prone to error 易于出錯, prone bombing 俯沖轟炸) readily prone for 易受 {.A thick body (large thickness/length ratio) is readily prone for separation and produces considerable pressure drag.} bluff body （blunt body） 鈍體 apparent 明顯的 sphere 球體 periodic oscillation 周期性振蕩 wake 尾跡 the eddies break off from the cylinder 渦從柱體上脫落 vortex street 渦街 degeneration of vortices into turbulence 渦退化為湍流 dramatic change (戲劇性的, 引人注目的，奇跡般的)變化 sustain vt. ①支撐[承持] ②持續(xù), 持久 {to sustain for a longer time 支撐更長時間} dimples on golf ball 高爾夫球上的小凹坑 trip v. ①釋放, 松開, 撥動 ②(使)跳閘, (使)解扣 {.to trip turbulence in order to decrease drag 觸發(fā)附面層轉(zhuǎn)捩成湍流以減�。▔翰睿┳枇� } bowling 保齡球(運動) bowlers 玩保齡球者；（板球）投手 cricket 蟋蟀，板球 vi 打板球 bowl [b.ul] n.①碗，缽，盆 ②[量詞]一碗一缽③(草地滾木球用之)木球；保齡球 v.滾(球），投(球) shin 攀，爬 delaying or stopping separation of flow 延遲或停止流動分離 |
