| 摘 要： | 本文采用时间连续无规行走(CTRW)的分形理论(Fractal),讨论玻璃超声弛豫过程中时间和空间无序对缺陷态激发寿命几率分布和特征弛豫时间的影响,并由此修正红外发散响应(IDR)理论,使其可能解释金属玻璃态超声弛豫现象。

| Abstract: | The effects of the space and time disorder on the survival probability of tunneling states and the relaxation time are analysed with the theory of continuous-time random walk (CTRW) on fractals. The infrared divergence response (IDR) theory is generalized and made possible to explain the relaxation phenomena in metal glasses. |
