摘要
针对瞬态声学散射问题中的第一类带Bessel核的Volterra积分方程,通过将变形方程与原方程联立求解,给出了Hermite配置方法.该格式的特点是振荡性越强,计算越精确.数值实验验证了格式的高效性.
For Volterra integral equation of the first kind with Bessel kernel of transient acoustic scattering problem,by combing transformed equation and primitive equation,Hermite collocation method is presented.The features of this method is that the higher the oscillation the more accurate the calculation.The high efficiency is verified by numerical experiment.
