Abstract
Bi-2212 superconducting whiskers were obtained by annealing a melt-quenched glass plate in a stream of oxygen for a long time. Different magnetic fiel d orientation was applied to examine the effects on the flux motion. The fl ux flow resistance in Wic is much larger than that in H//a and H//b. The fo ot structure can be treated as a superposition of a long resistance tail an d a dissipation peak regardless of the field orientation. This long resista nce tail was interpreted by K-T scaling behaviour. And the dissipation peak may be due to the hindered flux motion in the whisker with a high density of line dislocations.
