[求助] 溶出伏安分析法求助翻译一段文字

The BiBEwasmade in-house bymelting bismuth needles (99.998% purity, Alfa Aesar) into a hand-blown glass casing.
The melting process involved placing several rods of bismuth needles into the glass casing. A tin-coated copper wire was inserted partially into the glass casing such that the bismuth would melt around it and would act as the electrical lead. This ensemble was vertically inserted into a glass tube, which was then sealed and
connected to a vacuum line. Air from the tube was removed by vacuumand replacedwith nitrogen repeatedly to ensure complete removal of the air. The tube was held over a Bunsen burner until the bismuth was melted completely (melting point: 271.5 ◦C) This process was done under continuous vacuumto ensure that no air bubbles developed in the sealed tube. After cooling, the electrode was removed from the tubing and the end was cut with a diamond band saw, serving as the surface of the electrode.
