为探讨正常人脑电压缩谱阵特征，本文对３０例正常人按不同年龄分为三组，进行脑电图与ＣＳＡ对比分析。结果发现：α峰幅各组均以枕区最高，额区最低，但谱阵图型儿童组为α主峰型，青年组为单α峰型，中年组为单α峰型或峰不突出型；中心频率与边缘频率亦各有其相应特征，并能与谱阵图型一样实时显示出睁眼与过度换气时脑电图的变化。提示ＣＳＡ是一有用的脑电分析与监测方法
In order to explore the characteristics of normal people’s brain voltage depreciation matrix, 30 normal people were divided into three groups according to different ages in this article, and the comparative analysis of EEG and CSA was made. The results showed that: α peak amplitude in each group are the highest in the occipital region, the lowest amount of the frontal area, but the spectral pattern of the child group α main peak type, the young group of single α peak type, the middle group single α peak type or peak is not prominent Type; the center frequency and the edge frequency also have their own corresponding characteristics, and with the same spectral pattern shows open eyes and hyperventilation EEG changes. Tip CSA is a useful method of EEG analysis and monitoring
