| 摘 要： | １９９５年１０月２４日日偏食期间，我们在海南省琼中进行了地磁场总强度的观测和分析，同时运用该地磁台三分量磁照图，分析了地磁Ｄ场Ｄ、Ｈ、Ｚ三分量在日偏食期间的变化特征。结果表明：日偏食期间，磁偏角初亏后逐渐偏东，食甚后偏西；水平强度和总强度初亏后逐渐变小，食甚后上升；垂直强度初亏后逐渐变大，食甚后约１个小时变小。

| Abstract: | Geomagnetic total intensity was observed and analysed at Qiongzhong . Hainan Province . during partial solar eclipse Oct. 24 , 1995, Variation characteristics of geomagnetic three-com- ponent (D . H . Z)during partial solar eclipse were analysed by the three-component magneto- graph of this geomagnetic station. The results show that . during partial solar eclipse . geomag-- netic declination inclines to east after first contact and inclines to west after maximum eclipse , geomagnetic horizontal component and total intensity change small after first contact and rise after maximum eclipse , geomagnetic vertical component change big after first contact and change small in about an hour of after maximum eclipse. |
