摘要
In this work, the processes of ice film disappearance under a stimulant convection conditions and absorption to ethanol vapor to ice film were monitored by a quartz crystal microbalance (QCM) technique. The influence of the thickness of ice film on the response of the QCM was investigated by an impedance analysis method. It is shown that part of freshly prepared amorphous ice film on QCM is disappeared gradually during a stimulant convection process at -18 degrees C. We report a mulriple resonance phenomenon in QCM with unsymmetrical mass loading. The shape of the conductance-frequency spectrum of QCM depends on the thickness and distribution of the ice film deposited. After adsorption of ethanol vapor, the rigidity of the ice film is decreased gradually. With a large amount of ethanol adsorbed, the ice film is dissolved and evaporated completely. The QCM is a useful tool to monitor the mass and rigidity change of ice film.
