７８例健康人（７～７９岁），头部取四对电极点（ＦＰ１，２，Ｔ５，６，Ｏ１，２，Ｃ３，４），以三种常用谱分析法（功率，相对功率Ⅰ和Ⅱ）观察四个经典频带各参量量值的某些特征：１．多数频带量值与年龄相关。２．经多种年龄组合的Ｆ检验，可将７８例分为五组：７～１４岁、１５～１９岁、２０～３９岁、４０～５９岁、６０～７９岁。其中少年组（７～１４）、多数参量量值和老年组（６０～７９）α量值与其它年龄组的差异最显著。３．相对功率Ⅰ以及功率经Ｌｏｇ转换后多数量值呈（或近）正态分布。但并非各频段参量均能满足统计学要求。
78 healthy subjects (7 to 79 years old), four pairs of electrodes on the head (FP1, 2, T5, 6, O1, 2, C3 and 4) Ⅱ) Observe some features of the magnitude of each of the four classical frequency bands: 1. Most frequency bands are age related. 2. By a variety of age combinations of F test, 78 cases can be divided into five groups: 7 to 14 years old, 15 to 19 years old, 20 to 39 years old, 40 to 59 years old, 60 to 79 years old. Among them, juvenile group (7 ~ 14), most of the parameter values and the elderly group (60 ~ 79) α value of the most significant difference with other age groups. 3. The relative power I and the logarithm of the power after Log conversion are (or near) normal distribution. However, not all band parameters can meet the statistical requirements.
