2006年11月到2008年2月的所有XRT全日面数据中,筛选一些正好位于日面中心附近时的活动区、宁静区和冕洞区的Al-mesh和,Tj—poly全目面图像,利用Filter Ratio方法分别计算出这些活动区、宁静区和冕洞区的平均温度值.结果表明,活动区、宁静区和冕洞区的温度logT范围分别为6.7~6.85,6.2~6.45和6.1~6.2.
Some of the Al--mesh and Ti--poly filter XRT full disk images of the active regions, quiet re gions and coronal holes which located near the center of the sun are choosed during November 2006 to Feb ruary 2008. The average temperature of the three kinds of regions are computed. The results show that the temperature(logT) range of the active regions, quiet regions and coronal holes are 6.7-6.85,6.2-6 45 and 6.1-6.2.
