He stationed himself in a room commanding a view of the street, pacing the chamber with restless steps, stopping merely to listen from time to time for the sound of approaching wheels, then to cast an anxious glance on ali ; but the regularity with which the nubian puffed forth the smoke of his chibouque proved that he at least was wholly absorbed in the enjoyment of his favorite occupation
他走進一間面對著街道的房間，不安地在房間里踱來踱去，時不時地站住聽聽有沒有車輪漸近的聲音，然後用焦急的目光看看阿里，但見那黑奴依然含著他的長筒煙悠閑地在吞雲吐霧，這至少證明他是正全神貫注地享受他心愛的玩意兒。 -
Inside wall of pump chamber is adhibited with sound absorption material, equipped with double layer sound isolation door
水泵房等房間內壁貼吸聲材料。採用雙層隔音門。 -
To study the acoustic unsteady combustion of srm, built the acoustic model of chamber. deduced the little amplitude sound wave 3d equation, used the finite volume discrete method to simulate. got the vibration model of three kinds of chamber
為研究固體火箭發動機聲不穩定燃燒特性，建立了燃燒室內聲學特性分析的物理數學模型，推導了小振幅聲波三維波動方程，採用有限體積離散方法進行模擬，得到圓柱型、四片翼柱彤和五片翼柱型藥柱三種燃燒室形狀聲學振動基本模態 -
A rectangular box simulating the axial box of the lathe tool is manufactured ; experimental measurements of the surface vibration on the rectangular box and the acoustic field around the rectangular box corresponding to firstly a series of a homogeneous excitation and secondly two iii independent white noise excitations are taken in a semi - anechoic chamber. taking the vibratory properties as input, the properties of the sound field are calculated by the evsbpm and the sdsbpm respectively. the effectiveness and reliability of the evsbpm and the sdsbpm for the calculation of acoustic radiation problem is further verified from the comparison of the calculated results and measured ones
第五章設計加工了一模擬機床主軸箱的長方箱體，在半消聲室環境下，分別對其在單點處一系列簡諧激勵作用下和兩點處的獨立白噪聲激勵作用下的振動及其輻射聲場進行了實驗研究和分析計算，通過計算結果和實測值之間的比較，進一步驗證了改進體積源邊界合肥工業大學搏士學位論文點方法和統計分佈源邊界點方法計算振動聲輻射問題的有效性和可靠性。
