To measure the lateralvariation of a property, such as gravity or magnetic fields.
测量某种性质如重力场或磁场的横向变化。

The velocity points at the part where geological structure is complicated should be appropriately densified in order to picture the lateralvariation of velocity.
合成平均速度点的疏密主要由作图比例尺而定，在构造复杂的部位应适当地加密，以便控制速度的横向变化。
