用X射线衍射方法研究了几种核石墨样品的原子结构。通过传统的Rietveld细化方法以及CARBONXS模型分析了图案，该模型考虑了无序和堆垛层错。与那些从文献中编译的精炼参数揭示了所有石墨试样的结构的通用图片。
The atomic structure of several nuclear graphite samples, an essential moderator material for nuclear reactors, has been investigated by X-ray diffraction. The patterns were analyzed by the conventional Rietveld refinement approach as well as by the CARBONXS model, which takes into account disorder and stacking faults. The refined parameters compiled with those from literature reveal a generic picture for the structure of all graphite specimens.
