请教各位老师:我在一篇投稿中写道:Amplitude of low-frequency fluctuations (ALFF), which measures the total power of a given time course within a predefined frequency range (e.g., 0.01–0.08 Hz), has been proven to be a valuable parameter to reflect the intensity of regional spontaneous neural activity (Zang et al., 2007). 审稿人的回复意见是:“ALFF reflects the *power* but not intensity of regional spontaneous neural activity.”这里我有点困惑,请问我该怎么回复审稿人呢? 谢谢!

Re: 请问ALFF反映的是 "power" or " intensity" of regional ...
实际上,ALFF与power的平均根是比例关系。intensity一般指信号的强度,而amplitude of fluctuation反映的时间序列的波动幅度。比如,一个人多次的考试的平均成绩相当于信号的平均强度,而成绩的波动幅度就是信号的波动幅度。
