So, instead of'intermediate layer correction', we should adopt free air gravity anomaly and'topographic trend surface correction', which result in topographic trend surface free air gravity anomaly.
为此，应当不做“中间层校正”，而应代之采用自由空气重力异常加上“地形趋势面校正”之结果，以形成地形趋势面自由空气重力异常。
The tomographic inversion of the surface layer velocity model with the first break is the important base of the tomographic static correction.
初至波表层速度模型层析反演是层析静校正的重要基础。
This method is widely applicable because it considers how both static correction values and varied coupling of surface layer to shot point (or receiving points) influence wavelet phases.
由于该方法同时考虑静校正量及近地表和炮点、检波点耦会的变化对子波相位的影响。所以，此法具有更广泛的适用性。
