《振声学(第2卷)(精)》由尼尔森·A.C.和刘碧龙著，主要内容：The second volume of Vibro-Acoustics includes eight chapters. As in the first volume, each chapter ends with a number of problems. The solutions are given in a separate volume, which also contains a summary of some of the most important governing equations from the first two volumes.
