摘要：

All theoretical models of nanoflare heating in the solar corona predict loops with an unresolved multistrand structure, which is in discrepancy with the quasi-isothermal cross sections of the finest coronal loop structures observed with TRACE, which have spatially resolved widths of km. We suggest modifying the w approximate to 1000 - 2000 theoretical models by relocating the hypothetical nanoflare events from their coronal location down to the chromosphere/ transition region.
