| 摘 要： | 2008年8月1日,在我国西北的新疆、内蒙、甘肃等地区可以观测到一次日全食的天象,紫金山天文台太阳射电团组在甘肃省金塔用两架太阳射电望远镜对这次日全食进行了观测,并成功地取得了观测资料.为了科学分析观测资料,在日全食的前两天,实测了当地的大气吸收.着重分析这些观测数据,结合太阳射电方法,测得在λ=2.4 cm和λ=8....

| Abstract: | A total solar eclipse was observed successfully by solar radio telescopes at wavelengths of 2.4 cm and 8.6 mm in Jingta,Gansu province on 2008 August 1.Before the eclipse,the local atmospheric absorption was measured at these two wavelengths.Consistent with the previous findings,we obtained that the local absorption factors along the zenith direction are 0.012 Nb and 0.068 Nb,respectively.Using these values,the light curves of total solar eclipse are corrected by the atmospheric absorption atλ=2.4 cm andλ=8.6 mm. However,the results show that these light curves still need to be corrected by other factors, especially the strong absorption from the ground,before the further scientific study. |
