| 摘 要： | 我们对１９８３年日食闪光谱中的Ｄ３线进行了光度测量，加上比较可靠的定标系数，得到了氦Ｄ３线的绝对表面亮度分布，由此还求出了氦的密芳随高度的分布。其结果与以前观测结果大体一致。Ｇｕｌｙａｅｖ由统计发现，Ｄ３线的绝对亮度有着随太阳黑子数增加而下降这一趋势。我们的结果符合这一趋势。

| Abstract: | The flash spectra, obtained at the 1983 total solar eclipse, have undergone absolute calibration relably and have been reduced photometrically.We have obtained the surface brightness distribution of D3 line and then the density distribution of helium atoms.Our results are in agreement with those of some other observers. Gulyaev found that the absolute brightness of D3 line tends to decrease with the increase of sunspot numbers.Our result is conformable to this trend. |
