X-ray diffraction reciprocal space mapping measurements were conducted to investigate the crystal structure of ice of the Dome Fuji ice core. The broadening of the rocking curve of the ice crystals was caused by the dislocations introduced during the ice sheet flow. The dislocation density decrease with the increasing depth. The lattice constant c of ice is larger than that of the laboratory ice and decreases with the increasing depth while the lattice constant a is only slightly larger than that of the laboratory and increases a little with the increasing depth. These can be attributed to micro bubbles in the ice samples.

利用X射线衍射倒易空间成像技术研究了富士冰穹冰芯的晶体结构。冰晶摇摆曲线的加宽是由冰盖流动过程中引入的位错引起的。位错密度随深度的增加而减小。冰的晶格常数c大于实验室冰的晶格常数c，并随深度的增加而减小，而晶格常数a仅略大于实验室冰的晶格常数a，并随深度的增加而略有增加。这些可以归因于冰样品中的微气泡。
