咨詢內容：
A1:=DIFF<REF(DIFF,1) and REF(DIFF,1)<REF(DIFF,2) and REF(DIFF,2)>max(max(DIFF,REF(DIFF,1)),max(REF(DIFF,3),REF(DIFF,4))) and REF(DIFF,4)<REF(DIFF,3) and REF(DIFF,3)<REF(DIFF,2)；
這里是判斷一個波峰的方法，是以前的版主給的，現在回看到這里，發現這一句不知道目的為何： and REF(DIFF,2)>max(max(DIFF,REF(DIFF,1)),max(REF(DIFF,3),REF(DIFF,4)))
