  • neutral : adj 1 中立的；中立國的。2 不偏不倚，公平的；中庸的；中間的；不倫不類的，不明確的；不鮮艷的，暗淡...
  • buoyancy : n. 1. 浮力；浮性。2. 活潑，輕快；開朗。3. 【商業】漲風，上漲行情；（國家歲入的）增長趨勢。
  1. Around 40 ; the neutral curve obtained by the growth rates of the temperature fluctuation has a ringlike curve separated from the main branch of nachtsheim s calculation by velocity fluctuation at the lower grashof number side ; and its phase velocity is close to the maximum mean velocity where the critical layer of the eigenmode locates. the thermal fluctuation decays rapidly as the nondimensional frequency above 0. 4, so that it means that the coupling effect between instability wave generated by buoyancy fluctuation and velocity waves by invicid instability seems weak enough for their critical layers in the range of the nondimensional frequency

    詳細研究了自然對流邊界層中最早失穩的浮力振型的功率譜波長波速與臨界層位置等基本特徵和它為主導其他振型尚未失穩時按線性理論得到的3種相互獨立振型的振幅分佈。系統地測量了它所對應的溫度和速度漲落的振幅增長規律和中性曲線，實驗結果表明，溫度漲落的中性曲線在低格拉斯霍夫grashof數
  2. Buoyancy instability ; neutral curve ; vortex wave ; eigenmode
