根据本文提出的置换溶质原子－空位复合体扩散的机制，估算了ＨＣＰ晶体中某些具有异常快速扩散现象的溶质原子的扩散系数，结果表明复合体扩散机制可以很好地解释此现象。
Based on a mechanism proposed for diffusion of a solute atom-vacancy complex the diffusion coefficients and activation energies of some solute atoms,which diffuse anomalously fast in HCP crystals,are calculated.The mechanism could explain this phenomenon very well.Correspondent:CHEN Ning,Department of Physical Chemistry,University of Science and Technology Beijing,Beijing,100083
