vertical projection distance的意思|示意

In a vertical seismic profile, offset is the horizontal distance between the source and the wellhead or the surface projection of the receiver in the case of a deviated well.

在垂直地震剖面中，偏移距是震源和井口之间的水平距离。在斜井的情况下，偏移距是震源和检波器在地表的投影之间的距离。

Meanwhile, for a droplet falling freely under gravity with horizontal projection, the track model and the longest distance in both horizontal and vertical directions are obtained.

建立重力作用下作平抛运动液滴的轨道模型，得出了水平方向与竖直方向上的最大输运距离。
