目前电子计算机已经广泛应用于重磁异常的数据处理,借助于电子计算机利用磁异常的二维振幅谱来确定磁性体的埋深,是一个可行的方法。现对该方法作一简单介绍。一个周期函数,只要满足一些并不很严格的条件,就可以展成富里叶级数:
At present, electronic computers have been widely used in the data processing of gravity and magnetic anomalies. It is a feasible method to determine the depth of the magnetic body by means of the two-dimensional amplitude spectrum of magnetic anomalies by means of an electronic computer. Now the method for a brief introduction. A periodic function can be extended to Fourier series as long as some less stringent conditions are satisfied:
