| 摘 要： | 日全食是观测日冕的最佳机会。壮观的日冕显示复杂的形态结构和活动现象。日冕发射很强的紫外线和X射线，高温物质不断外流而形成“太阳风”，还常发生强烈的“日冕物质抛射事件”。日冕活动严重地影响空间环境和太空天气，因此日冕的观测研究成为对航天和地球有意义的热门领域。

| Abstract: | The total solar eclipse is the best opportunity to observe the solar corona on the ground. Magnificent solar corona shows very complex morphological structures and active phenomenon. The solar corona gives out strong ultraviolet and X ray，its matter with high temperature outflows continuously to form the solar wind. It often occurs with violent events of the coronal mass ejection . Coronal activities influence seriously on space environment and space weather，especially on spaceflight and the Earth. The observation and research of the solar corona becomes current hot field with important significance. |
