摘　　要：电化学石英晶体微天平(EQCM)同时结合了电化学检测的高灵敏度和石英晶体微天平(QCM)可实时检测电极表面质量变化及阻尼的特点,在电化学研究中具有非常好的应用前景,已得到越来越广泛的应用。本文设计了一种通用型的EQCM电解池,用恒电流电沉积铜的方法测定了QCM Pt电极的质量灵敏因子Cf,分析了Cf实验测定值与理论值偏差的原因,并讨论了在所设计的EQCM电解池中QCM Pt电极的使用范围,为进一步开展EQCM的应用研究提供可靠的基础。As the electrochemical quartz crystal microbalance （EQCM） is both of the high sensitivity of electrochemical investigation and the ability of detecting the variation of the surface mass and damp in situ as the quartz crystal microbalance （QCM） ,it gets more popular in electrochemical field. Aiming at the disadvantage of the traditional electrochemical cell, we have developed a universal EQCM cell adapted to electrochemical measurement. The design and characteristics of the new cell were presented. The sensitivity factor of the microbalance was determined by copper electro-deposition. Moreover, the reasons of the difference between the theoretical and experimental values of the sensibility factor was analyzed, then the EQCM using range was discussed.
