模拟地磁总强度的形态为近直线型，而数字化地磁总强度则有显著的日动态变化。
The change shapes of the imitative data of the geomagnetic total intensity shows a straight line and the one of the digital data appears a daily change.
模拟地磁总强度的形态为近直线型，而数字化地磁总强度则有显著的日动态变化。
The digital data of the geomagnetic total intensity observed more than 2 years and the imitative one are compared with each other.
与此同时，我们还统计了1957与1958年高纬度区31个地磁台在平静时每天的平均日变化。
We have also calculated the mean daily variation of K index of 31 stations of high latitude during the relative magnetic quiet period of year 1957 and 1958.
