论文摘要
染色层中各种明亮的结构在其动力学和进化中起着至关重要的作用。暂时识别外部太阳大气中的波特征有助于更好地理解这一层。这些特征最重要的方面之一是波相速度（PS），这是太阳冠状和太阳大气层中太阳能加热和能量分布的主要贡献。为了获得能量通量（EF），有必要计算填充因子（FF）和PS。在这项研究中，FF是通过跟踪虹膜明亮点（BPS）的大小和强度来确定的。为了估计精确的PS和EF，有必要了解色球圈和过渡区域（TR）厚度以及两个所需水平之间的相位差。染色体和TR厚度不能直接在椎间盘上测量；这项研究是使用光谱数据进行的，并基于多普勒速度进行校准。结果，已经使用多普勒速度的交叉动力小波变换计算了AR和CH中的PSS以及IRIS BPS。因此，关于CH，PS的平均值在网络上为40至180 km/s，在互联网工作中为30至140 km/s；大约是AR，网络上的80至540 km/s，在互联网工作中为70至220 km/s。最后，已经以三个不同频率计算了虹膜BPS的EF。结果表明，网络BP在加热较高的层中具有影响力的作用，而在互联网bps中，大多数能量都返回到下层。
Various bright structures abound in the chromosphere playing an essential role in the dynamics and evolution therein. Tentatively identifying the wave characteristics in the outer solar atmosphere helps to understand this layer better. One of the most significant aspects of these characteristics is the wave phase speed (PS), which is a dominant contribution to solar coronal heating and Energy distribution in the Sun's atmosphere layers. To obtain energy flux (EF), it is necessary to calculate the filling factor (FF) and the PS. In this study, the FF was determined by tracking the size and intensity of the IRIS bright points (BPs). To estimate an accurate PS and EF, it is necessary to know the chromosphere and transition region (TR) thickness and the phase difference between the two desired levels. chromosphere and TR thickness cannot be measured directly on the disc; This study is performed using spectral data and calibrated based on Doppler velocities. As a result, the PSs in AR and CH, as well as for IRIS BPs have been calculated using the cross-power wavelet transform of Doppler velocities. Consequently, about CH, the PS mean values are from 40 to 180 km/s at network and from 30 to 140 km/s at internetwork; And about AR, are from 80 to 540 km/s at network and 70 to 220 km/s at internetwork. Finally, the EF for the IRIS BPs has been calculated in three different frequencies. The results indicate that the network BPs have an influential role in heating the higher layers while in the internetwork BPs, most of the energy returns to the lower layers.
