【摘要】 Westervelt关于两个共线传播波束相互作用的理论结果仅适用于进行远场计算。本文从科研实际需要出发,将这一分析声波之间非线性作用的方法延伸到参量声源的源区内部。更多还原

【Abstract】 Westervelt’s approach to the calculation of non-linear effects in acoustic propagation is extended to the cases where transverse-dimensions of primary beams are taken into account and the observation point is within the interaction region.更多还原
