Liu, D. Lin, X. Wang] The magnitude of critical current density J c (or critical magnetic induction B c), is closely related to the flux pinning property of the high-temperature superconductors (HTSC) materials. So, the investigation on flux pinning mechanism is an important research field in the high-temperature superconductors. There are different pinning centers by analyzing the flux pinning force of the HTSC. In this study, based on Sun and Zou et al.'s previous works, we studied the flux pinning mechanism in Bi-2212 single crystals with an improved scaling function of pinning density, which is simplified and possesses determined physical meaning. Then, a computer simulation was conducted to determine the category of flux pinning in Bi-2212 according to Sun's experimental data. It is revealed that the simulation result is consistent with the experiment.
