摘要
在８小时睡眠脑电波（ＥＥＧ）分析中，通常有３０×１０６的ＥＥＧ信息被记录下来，对如此巨大的数据量进行分析，是一项非常枯燥费时的工作．本文首次提出了彩色统计地图法，极大地提高了信息表达密度，从整体上给出了数据的主要特征，为睡眠分析提供了一个简捷的方法．
During an eight-hour session of sleep analysis, 30×10.6 bytes of data is collected. Analyzing such enormous dare is time-consuming and tedious . This paper presents for the first time a colour map technique for the EEG signal analysis, with which the information can be displayed at a very high density and a general look on the data property is obtained. This technique provides a convenient method for sleep EEG signal anslysis and other biomedical signal analyses.
