对“用压缩质面法反演重力资料以估算地壳构造”一文的讨论

“用压缩质面法反演重力资料以估算地壳构造”一文发表在1977年第一期《地球物理学报》上。在应用过程中,我们发现一些问题,在此提出讨论。 1.平均密度问题 假定“深部重力异常”是由康腊界面与莫霍界面的起伏引起的(为了便于讨论,其它界面从略)。我们根据文献[1]作者常用的参数,做了两个起伏界面与对应的重力异常图(见

A DISCUSSION ON THE PAPER "INVERSION OF GRAVITY DATA BY USE OF A METHOD OF 'COMPRESSED MASS PLANE' TO ESTIMATE CRUSTAL STRUCTURE

This paper sets forth an adverse view on the calculation method expounded in the paper "Inversion of Gravity Data by Use of a Method of 'Compressed Mass Plane' to estimate Crustal Structure", published in No. 1, 1977 of Acta Geophysica Sinica. We believe that the author of the above-mentioned paper has adopted self-contradictory hypotheses on the distribution of crustal density in the process of continuous calculations, tus leading to an irrational decomposition of anomalies, forcing an unified solution upon problems which can be solved in many different ways. This is not in conformity with the principles of inferential interpretation of physical field, but also runs counter to the unrelenting logic in mathematics. The inversed computation of the assumed crustal structure models done by us testify to the fact that the results are irrational if we use the method introduced in the said paper to estimate the undulations of crustal interfaces.
