| Abstract: | 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. |
