On the basis of the analysis of existing models of equivalent electric circuits (EEC) of the quartz piezoresonators the possibility of application Batterworth-Van Dyke (BVD) EEC for a case of a piezoelement (PE) with an interelectrode air-gap and one-sided mass-loading is shown. The method of determination of parameters of EEC for quartz PE with an interelectrode airgap and one-sided mass-loading is given. The parameters of parallel and serial branches of EES and correlations for quality and capacity relation of PE is given. Comparison of the known and got correlations is conducted.
