摘要
从分布在欧亚美太平洋几个质量较好的台站的dY/dt变化曲线看,2000年或2001年似乎没出现新的Jerk(Y)。
The variations of dY/dt for several geomagnetic observatories were analyzed in this paper. It is believed that the qualities of these observatories are, relatively speaking, good. The results reveal that the 2000 or 2001 Jerk（Y） is not existed.
