New methods of measurements of specimen thickness and non-elastically scattering mean free path are proposed based on the electron holograph combining with electron dynamic diffraction.

而且，在电子全息照片和电子动力衍射相结合的基础上我们提出了一种测量电镜样品厚度和样品非弹性散射自由程的新方法。

Because the spin-flip length is longer than the electron mean-free-path in a metal, past studies of spin-flip scattering were limited to the diffusive regime.

金属中自旋翻转散射长度远长于电子平均自由程，近来关于自旋翻转散射效应的研究主要集中于扩散区域。
