摘要：
The spatial location of the Surface at which most of the prominence mass is concentrated is compared with the location of the "neutral Surface" where B-r = 0 (B-r is the magnetic field) calculated in a potential approximation using photospheric data. More than Fifty prominences (filaments) observed in 1999-2003 are Studied. The vertical deviations of the prominences (predominantly toward the west) correspond well to the inclination of the neutral surface. The results provide evidence for the magnetic Support of filaments of opposite polarities (the magnetic-rope model). (C) 2005 Pleiades Publishing, Inc.
