Any homogeneous viscoelastic medium subjected to one-dimensional tension and compression can be characterized in terms of the phase velocity c ( w ) and the attenuation coefficient deduce the complex modulus and the other equivalent viscoelastic functions 一維的縱向壓縮波在同質(zhì)的粘彈性介質(zhì)中傳播時,材料的粘彈性特性主要通過縱向波的傳播速度c(w)和衰減系數(shù)a(w)兩項來定義。
