Adaptive Constraint First Arrival lnversion
Realize the "seamless joint" between the LVL data and first arrivals by adopting adaptive constraint inversion.

The arrowhead notes the position of uphloes，through the adaptive constraint the result are much more closer to the velocity of upholes.

Case study of adaptive constraint inversion in loess plateau area，from the interval velocity of each 10 meters down from the topography, there are more low velocity information in the result, and much more closer to the actual geology condition.
