说明：  在三维地震勘探领域,野外实测坐标在资料处理时一般需要换算为相对坐标,这个需要进行根据已知方位角的计算相对应的坐标
(Three-dimensional seismic exploration in the field, field coordinates measured in the data generally need to handle the conversion for the relative coordinates, the need for the calculation of the basis of known azimuth corresponding to the coordinates)
