SEG关于极性的原文如下:
For a zero-phase wavelet, a positive reflection coefficient is represented by a central peak, normally plotted black on a variable area or variable density display. This convention is called positive standard polarity and the reverse convention is negative standard polarity or reverse polarity.
就是说子波为零相位时,一个正反射系数界面对应的反射是波峰,即变面积或变密度显示剖面上涂黑的部分。这叫做正标准极性,相反的就叫负标准极性或反极性
