摘要
研究了金属罐中具有频散性质波的传播特性,通过测量位移和波传播的时间导出计算公式,而得出声发射波在金属罐中的波速、幅值衰减随时间的变化规律,具有一定理论意义和工程应用价值。
This paper investigated the propagation property of dispersed wave in metal tank,educed calculation formula by measuring the movement and wave propagation time,concluded obtained the rule of time variation of wave velocity and crest value attenuation,and has a certain theoretical meaning and engineering application value.
