| 摘 要： | 本文采用低频涨落、耗散、弛豫过程的统一理论来研究玻璃热活化弛豫过程的超声吸收。与现有的弛豫时间分布理论不同,只采用单一弛豫时间τp,但可以说明弛豫时间分布理论所不能解决的玻璃超声吸收的实验特征,并解释这些实验特征与具体材料无关的普适性。

| Abstract: | Starting from the unified theory of low-frequency fluctuation, dissipation, and relexation processes, we studied the ultrasonic absorption in the thermal activation pro-cess in glasses. The theory involves only a single relaxation time and differs from the theory of distributed relaxation times. Nontheless, it can explain the experimental cha-racteristics of the ultrasonic absorption in glasses and the universality of these charac-teristics independent of kinds of materials, which couldn't be interpreted by the pre-vious theory with the distribution of relaxation times. |
