- air column resonance 气柱共振
- In wind instruments the sound is produced by a vibrating air column. 管乐器的声音是由振动的气柱产生的。
- A device in a brass wind instrument that permits change in pitch by a rapid varying of the air column in a tube. 活瓣在铜管乐器中通过在管中迅速改变气流而完成音调的改变的一种装置。
- The longer the pipe is, the longer the air column is, and consequently its inherent frequency and resonating frequency along with tone are low too. 管子长，空气柱也长，其固有频率和与噪声共振的频率亦低，声调就低。
- Everything else being equal, a cold air column, because of its higher air density, is heavier than a warm air column and thus produces a higher air pressure. 在一般相同情况下,冷空气柱因其密度较高,会比暖空气柱重,因而产生气压较大。
- Because of inertia, though, the air column continues to move up, leaving a partial vacuum in and above the glottis that acts to slam the folds more strongly together. 不过因为惰性的关系，空气柱还持续往上移动，使得声门及其上方形成半真空状态，这让声带闭得更紧。
- The mechanism and condition of gas column resonance, the influences of some factors on resonant frequencies, and the resonant features were investigated. 对气柱谐振机理、条件、有关因素对谐振激励频率的影响及谐振状态下管内振荡流特性进行了探讨。
- The air in the garden was warm and fragrant. 花园里的空气一片温馨。
- The archers sent their shafts through the air. 弓箭手向空中射出利箭。
- For the 2D photonic crystal (2D PhC) microcavity, a triangular array of air columns was adopted.The lattice constant and air columns radius are 1137nm and 456nm, respectively. 中文摘要本论文主旨在利用电子束微影术，完成边射型雷射、二维光子晶体微共振腔以及用来量测量子点之金属奈米电极之研制。
- In addition, we reduced the air columns around the cavity and simulated the photonic bandgap and fabricated the devices by E-beam lithography and deep dry etching process. 未来将会对共振腔的几何形状做修正来符合光传播时的场型，并以此设计做出元件并加以量测。
- The lack of air in the room make everyone sniffle. 屋子里空气缺乏，使得每个人都频频吸气。
- During the intermission, let's go out for some fresh air. 幕间休息时，我们出去呼吸呼吸新鲜空气吧。
- The air held a foretaste of a storm. 天气有要括大风的迹象。
- The air was reeking with the smell of tobacco. 空气中弥漫着烟草的气味。
- A walk in the fresh air will pep me up. 我在空气新鲜的地方散步就感到精神饱满。
- He served one month with the Air Army in Kuwait. 他在科威特的空军里服役1个月。
- Large air and navel forces were set into action. 庞大的空军和海军部队开始行动了。
- His modesty [air of joviality] was all put on. 他的谦逊[愉快的样子]都是装出来的。
- Ida was choking with the dry air. 空气干燥，艾达感到喘不过气来。
