摘　　要：为了更好地发挥正念的应用价值,探索并揭示其作用机制已成为相关研究的重中之重。脑电信号是一种方便且非常有效的研究手段,几乎蕴藏着正念过程中心理状态变化的全部信息。结合信号处理技术,从时域、频域、时频结合以及非线性特征量等方面分析正念脑电信号在不同角度下的物理意义及应用方法,这些方法有望为挖掘正念的作用机制提供理论、技术上的支持。In order to use the application value of mindfulness better,it is very important to explore and reveal its mechanism in relevant researches.EEG signal is a convenient and effective research means,and contains all information about the psychological change in mindfulness process.In combination with signal processing technology,the physical meanings and application methods of mindfulness EEG signal under different conditions are analyzed in the aspects of time domain,frequency domain,time-frequency combination and nonlinear characteristic quantity.The method is expected to provide the theoretical andtechnical supports for mining the mechanism of mindfulness.
