| Abstract: | In this paper, a further study is made on extracting information about the crustal vertical movements by Fourier--analysis. The relations between the upper--limited order of the model and the adjacent distance of levelling bench marks are derived. Also, the ways to obtain the reasonable solutions are given. |
