论文摘要
通过拟合观察到的等效宽度以及光谱线的中心深度和太阳能磁盘的中心和肢体的中心深度,可以通过越过太阳光球中大型和小规模运动的速度分布。我们使用了大约200菲I线条。根据我们的结果,光球的运动是各向异性的。微涡轮速度的径向分量从1.0降低至0.3 km/s,而切向速度的径向速度从200至500 km处从1.7 km/c降低至1.3 km/c(log tau_5 = -1.4和-3.5)。在相同的高度下,大型尿液速度的径向分量从1.8降低至1.2 km/s,切向切角从2.3至0.8 km/s降低。
The velocity distribution of the large and small-scale motion in solar photosphere has been obtained by crossing method based on fitting the observed and calculated equivalent widths as well as the central depths of the spectral lines at the center of the and the limb of the solar disk. We used about 200 Fe I lines. According to our results the motions in photosphere are anisotropic. The radial component of microturbulent velocity decreases from 1.0 to 0.3 km/s and the tangential one from 1.7 to 1.3 km/c at the photosphere heights from 200 to 500 km (log tau_5 = -1.4 and -3.5). At the same heights the radial component of the macroturbulent velocity decreases from 1.8 to 1.2 km/s and the tangential one from 2.3 to 0.8 km/s.
