Real materials, however, do exhibit an attenuation that must be accounted for in any complete description of an ultrasonic measurement system. Since the processes that generate material attenuation are generally quite complex, we will not attempt to model those processes in detail from a fundameSedative 发表于 2025-3-25 20:42:58
