摘　　要：通过对93例成年人头部电导纳图的导纳微分环及功率谱的测定分析,发现导纳图为弧形波和低平波两种波形的导纳微分环中的Ⅰ、Ⅲ、Ⅳ相面积有显著性差异(P<0.05),功率谱中的某些指标也有显著性差异(P<0.05)。By means of measuring 96 adults of the admittance differential loops and power spectral of electrical admittance cephalogram, significant difference(P < 0.05) was fond in some indexes of power spectral and in I II IV phases area of admittance differential loop between arc wave shape and low flat wave shape.
