摘要：
By introducing the concept of modified sound pressure, Helmholtz' equation is converted into another form of differential equation. On this basis, an infinite element approach is proposed to solve transient acoustic radiation in unbounded domain by establishing a new type of shape function, which does not need a wave-like factor. Numerical tests indicate that this approach is free from "rule of thumb" mesh adjustments. (C) 2002 Elsevier Science Ltd. All rights reserved.
