This review first summarizes the general theory of spin diffusion in solids, including semi-classical description and the more exact approach, i.
实验装置原理图如摘要附图1所示，可以测量电子自旋的双极扩散常数；
The experiment device schematic diagram is shown in the drawing 1 of the abstract and can be used to measure the ambipolar diffusion constant of electron spin;
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。
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.
