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.
针对该区的特点，在资料处理中建立了全区统一浮动基准面，应用折射静校正方法解决静校正问题。
To cope with these problems, we establish a floating datum in the whole area, and perform static correction with refraction static correction.
浮动基准面方法是将相对固定基准面的一份静校正量分解成两部分，并分别在动校正前、后应用的一种处理手段，这种分解是以CMP道集为单位的。
Floating datum method is divide the static of relative fixed datum into two parts that are applied to seismic data before and after NMO respectively and the division is done on CMP gather.
