Direct Mode‐Resolved Measurement of Interfacial Phonon Transport by Acoustic Phonon Reflectometry
Advanced Materials Interfaces, EarlyView.We introduce a novel analysis, acoustic phonon reflectometry, that measures the mode‐resolved phonon reflection coefficient at semiconductor interfaces. In aluminum nitride, we observe excellent agreement with the acoustic mismatch model across three distinct interfaces.

基于COMSOL Multiphysics的连续雷电流分量对OPGW断股分析
Dianci bileiqi, 2020 光纤复合架空地线（OPGW）的断股严重影响着电力系统的安全稳定性,为了研究雷电流对OPGW断股的影响,应用COMSOL Multiphysics对雷击点局部温度进行仿真,对雷电流C分量单独作用和连续雷电流A、C分量作用下的OPGW断股特性进行分析。结果表明:雷电流C分量对OPGW的破坏性较为严重,转移电荷量是产生断股的主要原因。连续雷电流A、C分量作用产生温度与断股程度均高于C分量单独作用,雷电流A分量对断股有明显影响。仿真结果为今后OPGW的抗雷击性能与机械性能研究提供参考。
