[en] 回顾了有关石墨扩散的可用数据。这导致了一个悖论：虽然石墨是一种高度各向异性的材料，但扩散几乎是各向同性的。此外，与金属中的自扩散不同，扩散不是通过空位过程发生的。考虑有关点缺陷的已知信息，随后将其用于检查可能的扩散过程。这些过程与其他元素的扩散形成对比。最后简单考虑一下石墨化的过程
[en] Data available concerning diffusion in graphite are reviewed. This leads to the paradox that, while graphite is a highly anisotropic material, diffusion is almost isotropic. Furthermore, unlike self-diffusion in metals, diffusion does not occur by a vacancy process. The known information about point defects, which is subsequently used to examine possible diffusion processes, is considered. These processes are contrasted with diffusion in other elements. Finally, the process of graphitization is briefly considered
