Popis:	Withintroductionofthefirst-orderstrain-gradie- nt of surface micro-beams into the energy density function, we developed a two-dimensional dynamic model for a com- pound quartz crystal resonator (QCR) system, consisting of a QCR and surface micro-beam arrays. The frequency shift that was induced by micro-beams with consideration of strain-gradients is discussed in detail and some useful results are obtained, which have important significance in resonator design and applications.
