| Abstract: | What highlights first in the paper is general aspects of velocity On the basis of the effects of velocity on different stages, the basic definition of each type, the specifically applicable scope and the obstacles to estimate The methodology of iteration is stressed with three actual instances First one is modelbased while the second one is processingprocedurebased Both of them are usimate stacking velocity The third one, an iterative procedure with feedback control conception, which is used in residual interval velocity analysis, is deliberately illustrated All of them together reveals the significance of that methodology Therefore, the importance of the methodology of iteration in geophysics is clearified |
