The study of non-linear EEG is of great significance in clinical practice and research work. This paper has gone into the feasibility of calculating the correlation dimension and has developed some subjects with the characters of correlation dimension and the difference under four conditions: (1) passive eyes closed(PEC); (2) mental arithmetic with eyes closed(MAEC); (3) passive eyes open(PEO); (4) mental reasoning with eyes open (MRED). The results show it is feasible and meaningful to calculate correlation dimension and the correlation dimension can reflect the regular patterns of mental activity.
非线性脑电图的研究在临床实践和科研工作中具有重要意义。本文探讨了计算关联维数的可行性，并对具有关联维数特征及在四种条件下存在差异的一些受试者进行了研究：（1）被动闭眼（PEC）；（2）闭眼心算（MAEC）；（3）被动睁眼（PEO）；（4）睁眼进行心理推理（MRED）。结果表明，计算关联维数是可行且有意义的，关联维数能够反映心理活动的规律模式。
