The nasal channel serves as nothing more than a resonator for the vocal vibrations that pass through it.
鼻腔的用途只是為通過它的聲音振動作共鳴器。The poem swung in majestic rhythm to the cool tumult of interstellar conflict, to the onset of starry hosts, to the impact of cold suns and the flaming up of nebular in the darkened void ; and through it all, unceasing and faint, like a silver shuttle, ran the frail, piping voice of man, a querulous chirp amid the screaming of planets and the crash of systems
那詩以莊重的節奏振蕩起伏，伴隨著星際沖突的清冷的波濤萬千星宿的前進步伐和無數冷冰冰的太陽的沖擊，伴隨著最黑暗的空虛望的星雲的燃燒而在這一切之間，卻傳來了入類微弱細小的聲音，有如一支銀梭，不斷地無力地吶喊著，在星球的呼嘯和天體的撞擊聲中只不過是幾聲哀怨悲嗟的唧唧啾鳴。Firstly the dissertation analyses the reason of vibration and noise of the transmission gear and the box, drawing a conclusion that the change of gear mesh rigidity and transmission error are the crucial causation to engender vibration and noise of the gear - box ; the main source of the noise is the syntonic noise in box vibration and noise
本文首先分別分析了變速箱傳動齒輪和變速箱箱體的振動噪聲產生機理，得知產生變速箱傳動齒輪振動噪聲的主要因素是輪齒嚙合剛度的變化和傳動誤差的影響;且在變速箱箱體振動噪聲中自鳴噪聲是汽車變速箱的主要噪聲源。Analysis of signal features about fruit fly ' s wing fluttering vibration
果蠅振翅鳴聲信號特徵分析So the pipe system sends out noise because of resonance. especially the frequency 250hz of pulsating water is in close proximity to natural frequency of pipe, so the 250hz is a dangerous frequency to the pipe system. there is another reason why the noise is reached to 110db ( a ) in pump room that the noise is magnified by the cistern because of the resonance of cistern
特別是激勵頻率為250hz的頻率分量恰好與管道系統的固有頻率相接近，其引起的管道振動對噪聲的貢獻最突出，同時也與水泵房房腔的固有頻率相接近，從而引起房腔共鳴發聲，使噪聲進一步被放大，以至於噪聲最大處高達105db （ a ） 。Note : do not over adjust. adjust only to the point where vibration or hum stops, not further. see fig. # 2
注：不要調節過度。調節過程要在振動或蜂鳴聲停止為止，不要過分。參閱圖2 。If adjustment is required, turn adjustment control with screwdriver in either direction slowly until vibration or hum stops
如果需要調節，則用螺絲刀從兩個方向慢慢旋轉調節控制，直到振動或蜂鳴聲停止。These regulators are provided with a compensating feature so that an adjustment can be made externally to eliminate any vibration, hum, or chatter conditions which may exist in the system due to certain operating flow requirements
這些調節閥都配置補償器，因此可以在外部進行調節，避免由於某種工作流需求而可能存在系統內的任何振動，蜂鳴或咔噠聲。分享友人
