▎ 摘　　要

NOVELTY - The method involves carrying out a preparation process of a bismuth superconducting material. A surface of a growing graphene is formed on a metal baseband. Bismuth/Silver superconductive strip material surface is welded with two sides of the growing graphene. The metal strip is connected to a reaction chamber. A reaction chamber vacuumizing process is carried out for 10-1-10-3Pa. Hydrogen is filled into the reaction chamber. The reaction chamber is heated. A heat preservation process of a metal strip is uniformly carried out. Methane gas is filled into the reaction chamber. USE - Bismuth superconducting material strengthening method. ADVANTAGE - The method enables achieving high strength characteristic of graphene, which effectively improves strength of the Bismuth/Silver superconductive strip material and expands application range of the Bismuth/Silver superconductive strip material. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a bismuth superconducting material strengthening method.
