大地电流野外记录的整理一般要求较长的时间与较大的注意力,这是由于有必要找到许多变化矢量以便达到所需精度的缘故。下面我们将叙述一种利用一个简单的工具即可大大提高解释工作速度的方法。大家都知道,大地电流变化矢量终点的平均值,如果是在一段适当的时间内记录下来的,表明橢圆的 The finishing of field current field records generally requires longer time and greater attention due to the need to find many variation vectors in order to achieve the desired accuracy. Below we will describe a way to greatly improve the speed of interpretation using a simple tool. As we all know, the average of the endpoints of the vector of the earth current change, if recorded for a reasonable period of time, indicates that the elliptical
