“热点”中局域声子的动力过程

Dynamic Process of Local Phonon in"Hot Spot

利用玻尔兹曼方程研究“热点”中的非平衡局域声子气，得到了反映“热点”中局域声子气分布的弧子型解，并对该解的物理意义进行讨论。结果与实验符合得很好。

Nonequilibrium local phonon gas was investigated by solving nonliner Boltzmann equation. The solitonic solution of local phonon gas in 'hot spot' was obtained, and then the physical meanings were discussed. The theoretical result was good agreement with the experiments.
