Introducing the theory and application of boundary element method on the sound radiation , giving the process of solving vibration noise radiation problem using boundary element analysis software ; presenting the coupling theory and the combination analysis of finite element method and boundary element method , and doing relevant analysis based on close drum shell ; programming the noise data simulation program using the numerical calculation software , simulating the acoustic and pressure data of a key point in the transient response acoustic field of the close drum shell , realizing the audibility of the noise , using the virtual reality tools to simulate the vibration noise of the drum shell ; combining the finite element method and boundary element method to analyze the vibration noise radiation of some gear box , and completing the whole simulation process of the vibration noise of the gear box 綜合介紹了邊界元法在聲輻射問題上的理論及應用;并給出了運用邊界元法分析軟件求解振動聲輻射問題的過程。闡述了有限元法和邊界元法的耦合理論及組合分析方法,并以封閉鼓形薄殼為分析對象進行了相應的分析。利用數字計算軟件編制了噪聲數據模擬程序,并模擬了通過組合方法分析封閉鼓形薄殼瞬態響應聲場而獲得一關鍵點的聲壓數據,實現聲音的可聽化,隨后通過虛擬現實工具實現了該情形下橢球殼振動噪聲的虛擬仿真。

Youth sometimes audibility the 3rd heart sounds , originate diastolic when blood the room wall that from atrium irruptive ventricle produces is oscillatory 年輕人有時可聽到第三心音,來源于心臟舒張時血液從心房沖入心室產生的室壁振動。

Will stethoscopic wall of bosom of the area before be being put to the heart , audibility every normal cardiac cycle by “ dong “ , “ da “ two composition 將聽診器放至心前區胸壁,可聽到每個正常心動周期由“咚“ 、 “噠“兩聲組成。

Sometimes audibility is other heart sounds or murmur , likely disease place causes want an attention 有時可聽到其他心音或者雜音,要注重有可能是疾病所引起的。
