    本文研究了聲強測量技術在汽車噪聲源識別中的應用。通過使用兩個微型雙麥克風和支撐它們的框架，我們設計了一個小型的聲強探測器，用它來實現對汽車噪聲源的聲強探測。
  2. It is proved by measuring noise of fan room of jcfk, that there are pretty good agreements between estimation and experiments. then, this model is applied for the practical engineering of noise control in fan room. the ways to connection qualitative with quantitative, analysis in theory with policy decision in practice are successfully used and the optimal scheme of noise control is achieved. moreover, the effect of the optimal scheme is estimated. this paper makes considerable headway about not only the research range and content but also the theoretical basis and research method. it has the important practical value

    把模型運用於復烤廠風機房噪聲污染治理的實際，採用定性分析與定量分析，理論計算與經驗決策相結合的方法，對風機房車間噪聲控制，隔聲間噪聲控制和傳播途徑噪聲控制三方面系統研究，制定風機房噪聲控制優化方案，並編程預測治理效果。這不僅將噪聲污染監測，評價治理，預測的研究有機地結合起來，拓展了研究范圍和內容，而且研究方法有所創新，對當前工業噪聲優化控制有較強的推廣和應用價值。
  3. This will be dealt with in this paper. the discrimination for noise source from qn700 indicates : the fan noise ( 625hz ), the electromagnetism noise ( 962hz ) and the burning noise are the main noise sources

    對汽車燃油空氣加熱器中具有典型代表結構的qn700型樣機的測試分析表明：風扇噪聲（ 625hz ） 、電機噪聲（ 962hz ）和燃燒噪聲是加熱器的主要噪聲源。
