用于反演重力资料以估算地壳构造的压缩质面法最早由刘元龙和王谦身提出。后来,沈剑平与王和明又进一步提出了用于反演不等点距重力资料经预调整的压缩质面法。笔者根据海区的特殊情况,运用此法进行了多项试验性计算。具体作法是:<1>将布格重力异常平滑滤波后不等点距采样并考虑沉积层的影响;<2>等点距取平滑滤波后的布格重力值进行计算;<3>等点距取自由空气重力异常值,用二维方柱体公式正演作水层布格改正,
The compressive surface method used to invert the gravity data to estimate the crustal structure was first proposed by Liu Yuanlong and Wang Qian-shu. Later, Shen Jianping and Wang Heming further proposed the compressive surface method used to inversely reconstruct the unequal-point gravity data. Based on the special circumstances of the sea area, the author conducted a number of tentative calculations using this method. The specific practice is: <1> to Bouguer gravity anomalies smooth filtered unequal spot sampling and taking into account the influence of sediment layer; <2> equal distance to take the smooth filtered Bouguer gravity value calculation; <3> From the free-air gravity anomaly value, using two-dimensional square cylinder formula for forward correction of the water layer Bouguer,
