typical a. 典型的 macroscopic scale 宏观尺度 packets of fluid 流体小包 turbulence viscosity 湍流粘性 eddy viscosity 涡粘性 as a consequence 作为结果 growth rate 增长率 separation of flow 流动分离 immensely ad. 无限地, 广大地, 庞大地 (Pressure gradient is one of the factors that influences a flow immensely.) retarding effect upon the flow 对流动的阻滞减速作用 favourable pressure gradient (negative pressure gradient) 顺压梯度 adverse pressure gradient (positive pressure gradient) 逆压梯度 to separate the flow 使流动分离 counteract vt. 抵消; 阻碍; 中和; 使受挫 from this point onwards 从这点往后 reverse 倒流 （.The flow reverses.） recirculating flow 回流 contour of the body 物体的外轮廓 point of separation 分离点 terminate v. 终止 reattach v. 再附（着） separation bubble 分离气泡 drag 阻力 skin friction drag 表面摩擦阻力 pressure drag or form drag 压差阻力(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…倾向的(to) ②俯伏的, 面向下的 ③倾斜的, 陡的 (.be prone to error 易于出错, prone bombing 俯冲轰炸) 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） 钝体 apparent 明显的 sphere 球体 periodic oscillation 周期性振荡 wake 尾迹 the eddies break off from the cylinder 涡从柱体上脱落 vortex street 涡街 degeneration of vortices into turbulence 涡退化为湍流 dramatic change (戏剧性的, 引人注目的，奇迹般的)变化 sustain vt. ①支撑[承持] ②持续, 持久 {to sustain for a longer time 支撑更长时间} dimples on golf ball 高尔夫球上的小凹坑 trip v. ①释放, 松开, 拨动 ②(使)跳闸, (使)解扣 {.to trip turbulence in order to decrease drag 触发附面层转捩成湍流以减小（压差）阻力 } bowling 保龄球(运动) bowlers 玩保龄球者；（板球）投手 cricket 蟋蟀，板球 vi 打板球 bowl [b.ul] n.①碗，钵，盆 ②[量词]一碗一钵③(草地滚木球用之)木球；保龄球 v.滚(球），投(球) shin 攀，爬 delaying or stopping separation of flow 延迟或停止流动分离 |
