以下为句子列表:
英文: In the wavefield-spread area, we uses the phase-shift operator as constraint in frequency-wavenumber field, while beyond the wavefield-spread data, we uses zero point at the ends of phase-shift operator as constraint to take discrete smooth interpolation
中文: 通过离散光滑插值法,在频率-波数域中,以传播区内的相移算子为约束,在传播区外的算子两端处以零点为约束,进行离散光滑插值,使得所得算子具有二阶光滑可导性,则其对应的频率-空间域中的算子就可以取得很短。
