本文讨论了三个问题:一、对固体与液体中纵波声场作了对比,指出了固体中声场的特殊性,阐明了自液体中导出的声场公式适用于固体的条件范围;二、论述了脉冲波与连续波的区别与联系,脉冲波可以按傅里叶分析作为无限个正弦和余弦波之和,在此基础上可以用连续波声场的结果分析脉冲波声场,还指出连续波声场公式适用于脉冲波声场的条件和范围;三、介绍了严仁博有关横波声场理论和计算工作,综合概述了 I.N.Ermolov 和 J.Prepechal 两人的有关工作,并给出了斜探头横波声场的理论结果。
In this paper, we discuss three problems: Firstly, we contrast the longitudinal wave field in solid and liquid, point out the particularity of the acoustic field in the solid, and clarify that the formula of sound field derived from the liquid is suitable for the range of solid condition. Secondly, The difference between wave and continuous wave, the pulse wave can be Fourier analysis as an infinite sum of sine and cosine wave, on the basis of the continuous wave sound field results can be analyzed pulse wave field, also pointed out that continuous wave sound field formula applies The conditions and range of the sound field of the pulse wave are introduced. Third, Yan Renbo’s theory and calculation of shear wave sound field are introduced. The related work of INErmolov and J.Prepechal are summarized.
