- 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。
- Silica gel column separation method and spectrophotography were used to determine the content of urson in the preparation. 采用硅胶柱分离分光光度法,对制剂中所含熊果酸成分进行含量测定,结果含量测定的标准品线性关系好,检测数据稳定。
- English: The item spacing decides the distance (in pixels) between the items and anything else: the view borders, other items or column separators. 条目间隔决定了条目之间以及条目和其它部件,比如视图边框、其它条目或者栏分隔线之间的距离(以像素点数计)。
- The name and definition of the table columns separated by commas. 指定表中列的名字和定义,列之间用逗号分隔。
- The principle of EPC has been introduced herein, and its application whereto sample injection and column separation was demonstrated on the analysis of pesticides by GC/MS. 文章叙述了电子压力控制技术在气相色谱中应用的基本原理,并以农药样品分析为例介绍了它在进样和柱分离时的作用。
- 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。
- By using a non-polar column separation, the equilibrium conditions for the determination of residual solvents in edible vegetable oils by headspace gas chromatography (HSGC) have been developed. 在采用非极性色谱柱对溶剂组分进行分离的基础上,对食用植物油残留溶剂顶空分析的相平衡条件进行研究。
- 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。
