In the surveys, some very closely spaced survey lines displayed remarkable differences in crustal structure. To find the reasons for the differences and to analyze the reliability of crustal structure, ocean bottom seismometer data from the west and east sides of the Dongsha Islands were reprocessed and inverted with tomography technique. The routine processing and inversion procedures include clock correction, position correction, finite-difference ray-tracing-based tomography, checkerboard test and comparison of the inverted crustal model with initial models. As a key step, we analyzed the lateral velocity resolution and smoothed out the short wavelength velocity variation which maybe most probably artifacts in the final velocity models.

在一些相隔很近的测线上，探测的深部地壳结构却相差较大，为了分析这些探测结果中差异的原因和地壳结构变化的可靠性，本文以东沙东侧海域测线和东沙西侧海域测线为例，对采集的海底地震仪记录进行了时间、位置校正和初至波走时拾取，利用有限差分地震走时层析成像进行了走时反演，获得所在剖面的地壳速度结构，并分析了模型的横向分辨率，剔除模型中短波长的横向速度变化。
