月球风暴洋地区玄武岩厚度的重力研究

利用剩余布格重力异常进行月球表层玄武岩厚度的推断，为月球地质填图提供了一定的证据。文中利用美国GRAIL卫星660阶布格重力异常，采用巴特沃斯（Butterworth）滤波方法，参考Grant H. Herken等的研究成果（即对月球面向地球一面的玄武岩厚度研究推断），以此作为控制条件，提取了风暴洋地区的剩余布格重力异常，参考遥感光谱反映出的玄武岩范围，然后利用边界元方法反复模拟修正，最终得出该区的玄武岩厚度分布，玄武岩的厚度不超过1.5 km。

A study of the depth of basalt in lunar Oceanus Procellarum

The paper uses Residual Bouguer anomaly of gravity to infer the depth of basalt in the lunar regolith, which provides evidence for lunar geological mapping. On the basis of the results of Grant H. Herken et al.(1993), Residual Bouguer anomaly of gravity in Oceanus Procellarum is first extracted by Butterworth filtering from GRAIL 660 Bouguer anomaly of gravity in this area. The extent of basalt in Oceanus Procellarum is outlined by remote sensing spectra. And the boundary element method is used to repeatedly simulate and correct the model. Finally, the basalt depth distribution of this area is attained. The depth of basalt in Oceanus Procellarum is less than 1.5 km.
