In the BEM model, the radiation impedance boundary condition at air intake surface is used and the results demonstrate that it is superior to the traditional pressure release boundary.
本文中空气入口边界采用辐射阻抗边界，优于传统的将入口边界压力当成零的软压力边界。
The proposed finite difference boundary condition expands the scope of application of FDTD to scattering problems of objects with a finite acoustic impedance but without tangential stress.
导出了水中透声目标表面边界条件的时域有限差分(FDTD)表达形式，将FDTD在水声学中的应用范围扩大到无切应力的有限声阻抗目标的散射问题。
