试验结果表明，采用水平基准面两步法静校正，时间剖面反演深度误差最小；
The results were as follows. The horizontal datum and two-pass statics method gave minimum depth error on time section.
实际上浮动基准面还是水平基准面，只是不同CMP的水平基准面高程可以变化。
Actually, floating datum is still horizontal datum, but the datum elevation of different CMP is variable.
在作偏移处理时，一般要求偏移基准面是水平的，且偏移的零点应在激发和接收的地表。
In migration processing, we usually require that migration datum is horizontal and that zero point for migration should be on the ground surface on which shot point and receiving points lie.
在基准面重建时，利用CRS运动学波场参数可将CRS叠加剖面校正到一选定的水平面上。
The CRS-stacked zero-offset section can be corrected (redatumed) to a given planar level by kinematic wave field attributes.
