摘要：

In the present work, we used optical and X-ray data from the Hinode satellite to study the response of the solar chromosphere and the corona to the emerging flux in the photosphere. In total, twelve emerging flux regions (EFRs) were selected to conduct this study. The average separation of the two polarities and the lifetime of these EFRs were 3 ''.2 and 40 min, respectively. All of these regions showed corresponding enhanced emission in the Ca II H line and soft X-rays with different filters, indicating that these small-scale and short-lived EFRs heat the chromosphere and the corona to some extent.
