1 受压炮孔波辐射的快速而有效的解 (D .P .Blair -澳大利亚 )柱状炮孔波辐射标准时域解已改写为傅立叶逆变换 ,这就能够使用快速傅立叶变换 (FFT)技术求解。FFT技术既快捷又有效 ,尤其是 ,FFT方法曾经比用梯形法则求值的标准时域积分平均快 4 4 0 0倍以上 ,比标准积分由Euler
1 A Fast and Efficient Solution of Compressive Barrel Wave Radiation (D.P. Blair - Australia) The standard time-domain solution to columnar shothole wave radiation has been rewritten as an inverse Fourier transform, which can be solved using Fast Fourier Transform (FFT) techniques. The FFT technique is both fast and efficient. In particular, the FFT method has averaged more than 4 4 0 0 times faster than the standard time-domain integral evaluated with the trapezoidal rule,
