绝大多数这样的涡流完全是能量向上运转的螺旋.
Venus Express also focused on vast rotating vortexes of clouds at Venus'poles.
“金星快车”号还集中观测了金星极地的大型旋涡云.
In comparison with 30 ° air inlet, the generated vortexes are fewer, weaker and nearer to the air inlets when the inlet angle is 45 ° along the axial cross section.
与30°进气道相比,沿轴向横截面上45°进气道所形成的回流区向进气道一侧偏移,回流区区域减少,强度减弱。
