提出了一种用于连续监测真空或单面接触流体介质的石英晶体微天平运动串联谐振频率的新电子设计。本文介绍了一种直接测量动阻的方法，并介绍了一种测量巴特沃斯-范戴克等效电路的L参数和C参数的简便方法。计算结果与阻抗分析仪的测量结果相吻合。(C)2000年美国物理研究所。[S0034-6748(00)04806-1]。
A new electronic design for continuous monitoring of the motional series resonant frequency of a quartz crystal microbalance either in vacuum or in single-face contact with a fluid medium is presented. The motional resistance is directly measured and a simple method for measuring L and C parameters of the Butterworth-Van Dyke equivalent circuit is described. The results are in agreement with impedance analyzer measurements. (C) 2000 American Institute of Physics. [S0034-6748(00)04806-1].
