日冕及其观测演示实验

摘要

搭建了日冕演示实验系统，通过模拟STEREO双子卫星围绕太阳轨道观测日冕的工作模式，可直观演示太阳表面的常见日冕结构、外掩式日冕仪遮挡光球观测的原理，以及由双星观测结果进行日冕三维重建的方法。讨论了将该演示实验系统用于太阳物理和空间探测技术课程教学的意义和实验方法。%An experimental demonstration of shape of solar corona and its observation was set up for teaching purposes ,which could simulate the operating mode of the two STEREO solar‐corona‐pro‐bing satellites orbiting the sun .Owing to the simulation system ,the common corona structures ,the working principle of externally occulted coronagraph ,and the 3D reconstruction of corona on the basis of the observations of the two satellites could be visually demonstrated .The significance and experi‐mental method of utilizing the simulator in solar physics and space probing technology courses were discussed .
