| 摘 要： | 本文提供了一个事实:同纬度不同经度台站的S_q曲线可以有很大的差异。对拉萨台的S_q异常作了一些初步的、定性的分析与解释。对八丈台的S_q异常则认为难以解释,值得深入研究。

| Abstract: | This paper shows a picture that the S_q variations for different observatories,which are located at the same latitude but different longitude,may have quite different features. The anomalous feature in the S_q variation for the Lhasa observaitory can be qualitatively interpreted as that a shallower highly conductive layer might exist in this region.However,it is very difficult to give a reasonable explanation to the anomalous feature in S_q variation for the hatizyo observatory. |
