摘要：

We made the superconductor of Bi2Sr2CaCu2O7by the solid state reaction. According to the results of measurement by infrared spectrophotometer with the varying of wave number from 4000 to 400 cm-1. We discovered three infrared absorption peaks at room temperature, i.e., peak A, at 500–550 cm-1, peak A2 at 800–840 cm -1 and peak A3 at 1370–1420 cm-1. We find that peak A, is due to impure phase, peak A2 is related with the crystal structure and peak A3 is caused by the vibration of the atom layers of calcium. © 1990, Taylor & Francis Group, LLC.
