The spectra in the IR line He I 10830 Å, the soft X-ray images taken from the Yohkoh satellite, and the magnetic structure in places of bright solar-activity regions, where intense coronal heating in the absence of flares has been recorded, are studied. Several regularities in the interaction between an active region with a strong magnetic shear and a neighboring coronal hole are established. It is assumed that, as a result of magnetic reconnection processes, which constantly take place and involve the open lines of force of the magnetic field of the coronal hole and the (basically) closed lines of force of the active region, bright coronal structures are formed.
