vertical fins

同根派生

The prototype to be flown on May 10 has been modified with work done on its air-intakes, strake and vertical fins, besides modifications in the fuselage.
这架重新设计了机身进气道，边条和腹鳍的新型原型机将于5月10日正式试飞。
For the vertical fins and slats on the treehouse we'll be using sustainably-grown pine and poplar respectively.
. 至于那些直鳍形条板和其他板条，我们分别采用可持续生长的松树和白杨木料。”
The two vertical fins on the nose, around 40 cm high, give the car an unconventional look, but fall within regulations regarding bodywork height.
两片位于鼻锥，直立大约40公分高的鳍让这辆车有著非传统的外观，但是并不违反关于车体高度的规定。
They also use longer torsion bars (red arrows), which are covered by two vertical fins in the rear bodywork (see previous engine cover drawing).
车队亦换上了较长的扭力杆（红色箭头处），这些扭力杆被车体后方垂直的鳍所遮罩（见下方引擎外罩的插图）。
Another new detail is on the turning vanes, which now feature a triangular, vertical fin (2).
另一项新细节在导流翼上，现在这片小翼变成一个三角形且垂直的鳍（2）。
