摘　　要：目的:探讨气功意守状态下脑电非线性变化特点。方法:用多道动态生理记录仪对正常人和气功练习者进行脑电信号采样,分析多道脑电相空间重构的相关维数D2。结果:意守状态下D2都有升高,气功练习者在意守状态下有较长时间的稳定期。结论:意守状态下较长时间的D2稳定期有可能反映气功意守能力。Objective： To explore the characteristics of nonlinear changes of eleetroencephalograph（EEG） at Qigong medi- tation. Method： Multi-channel Hoher was adopted to sample the eleetrocerebral signals in 8 Qigong practitioners and 11 ordinal people, and analyze the correlation dimension D2 of EEG phase-space reconstruction. Results： D2 increased at Qigong meditation in all testees and sustained for a longer period in Qigong practitioners. Conclusions： Sustained period of D2 increase at Qigong meditation may reflect the level of Qigong practitioners＇ meditation.
