  “声失配理论”译为未确定词的双语例句
     Because there is a limit of roughness and temperature in AMM and DMM, the data of the theory model that is directly built by AMM and DMM is far from the experimental data. Accordingly, with DMM and traditionary methods, the mathematics model is posed by contrast and analyses of the experiment data.
     由于声失配理论和散声失配理论对温度和粗糙度有很严格的要求,所以直接建模所得的理论数据与实验数据有很大的差距,本文采用声失配理论与传统研究方法相结合,通过与实验数据的分析拟合,提出了修正的数学模型,预测误差有了大幅度的提高。

  acoustic mismatch model
The comparison with theoretical model calculations of phonon transmission across the interface yields agreement with the isotropic/anisotropic acoustic mismatch model.
      
Our observations of the reflection or backscattering of high-frequency phonons (v =280 GHz to 1 THz) at silicon-solid interfaces disagree significantly with predictions from the acoustic mismatch model.
      
Those rates may be orders of magnitude larger than obtained by the acoustic mismatch model even in frequency regions with practically linear phonon dispersion relation.
      
To consider the thermal boundary resistance between film and substrate, an interfacial-layer model (ILM) with very low diffusivity and an acoustic mismatch model (AMM) are employed.
      
For a sample with a polished interface, good agreement with acoustic mismatch model was found up to about 20 K.
