微晶玻璃中的声传播

Sound propagation in glass-ceramic

摘要: 本文把悬浮液中的声学处理方法应用到微晶玻璃中,导出了微晶玻璃中声速和声衰减系数随结晶度变化的表达式,并通过实验进行了证实。

Abstract: The acoustic theory of the suspensions is applied to the study of acoustic properties of glass-ceramic. The relations between the sound speed and the sound attenuation with the crystallinity in glass-ceramic are derived The theoretical results are verified by the ultrasonic experiments.
