The carbon layers stacking sequence of stage 2 K GIC inferred by the model is same as that determined by experiment. The carbon layers stacking sequence of stage (2 4) guessed by the model should be a|ab|bcbc|ca|abab|bc|caca.

• 利用我们提出的模型推测 3阶钾 -石墨层间化合物向 2阶转化过程中碳层堆积顺序的演变 ,从理论上推测出的 2阶钾 -石墨层间化合物碳层堆积顺序与实验测定的结果完全一致 ,并推测 (2 - 4)阶的堆积顺序为 a|ab|bcbc|ca|abab|bc|caca
