中文摘要：
提出了以混合波叠加法作为声场的全息变换算法，建立了基于混合波叠加法在声源识别中的理论模型。此法用相对少量的测点数据就可重建任意形状源表面的声场，克服了基于边界元法的声全息中的奇异值积分和解的非唯一性难题，数值仿真结果表明：它具有计算速度快、重建精度高、测量成本低和容易实施等优点，可以精确地识别和定位机械噪声源，在工程实践中具有广泛的应用前景。
英文摘要：
A combined wave superposition method is proposed to transform near-field acoustic holography. A theoretical model to identify sound sources is established. The method allows reconstruction of the acoustic field from an arbitrary object with relatively few measurements, and overcomes nonuniqueness and ill-posedness difficulties. Numerical simulation shows that it can identify and localize sound sources. avoid reconstruction very time, and reduce cost, thus significantly enhancing the reconstruction efficiency. It can become a powerful noise diagnostic tool in engineering.
