- W2391895295 abstract "Working principles and specifications of a liquid film resonant absorption mechanical spectrometer were presented. By using this home made spectrometer, the resonant absorption mechanical spectrum of water film with thickness of 0.1 mm was obtained. There were 8 resonant absorption peaks in a frequency range of 150 Hz to 550 Hz. Compared with the resonant frequency of the empty apparatus system, which was lower than 150 Hz, the resonant frequency of the apparatus system with 0.1 mm thick water film was higher than 550 Hz. It indicated that the water film had participated in the mechanical vibration and provided restoring moment to the apparatus system. Therefore, all 8 resonant absorption peaks obtained are inherent resonant absorption peaks of water film and the resonant absorption peaks of 178 Hz and 476 Hz are resonant absorption peaks resulting from the cooperation of water film and copper thread, a vibration producing element." @default.
