开放式圆柱形管的末端修正：理论和实验确定。对于零频和低频，采用有限差分法对波动方程进行数值求解。对于较高的频率，测量了复辐射阻抗；对于圆形范围，用边界元法计算。对于低频，边界元与频分复用相结合，对于高频，边界元与实验结果相吻合。在乐器中发现的各种范围被考虑：各种尺寸的圆形范围，球形和圆柱形法兰，方形范围：标准化范围（用于扬声器测试），短喇叭口和开放端以上一定距离的磁盘。针对每种情况提出了解析拟合公式。(C) 2001学术出版社。
End corrections for open-ended cylindrical tubes art: determined theoretically and experimentally. For the zero and low frequencies, the wave equation is solved numerically by using a finite difference method. For higher frequencies the complex radiation impedance is measured and For circular Ranges, calculated with the boundary element method. For low frequencies the BEM links up with the FDM and for higher frequencies fits with experimental results. Various Ranges found in particular in musical instruments are considered: circular Ranges of various sizes, spherical and cylindrical flanges, square Ranges: the normalised Range (used for loudspeaker testing), short flaring horns and a disk at a certain distance above the open end. Analytical fit formulas are proposed for each case. (C) 2001 Academic Press.
