摘要
根据多面体重、磁异常频谱的表达式,编制了在微机上频率域作正演的程序。为了获得满意的结果,我们合理地解决好三个问题。第一是频率等于零时取极限值的问题,我们采用的是线性外推方案;第二是频率的采样密度;第三是截止频率的选取。
A progrom is written to compute the gravity and the magnetic anomaly of a polyhedron from spectrum. TO obtain satisfactory results, three problems must be solved reasonably. 1. Treatment of zerofrequency. 2.Interval of sampling in frequency domain. 3. Cut-off frequency.
