摘要：

The high mass sensitivity of the quartz-crystal microbalance is explained by the very high acceleration of the particles on the surface of the quartz resonators. The sensing properties of quartz resonators in contact with a solid, liquid or gas medium are explained within the energy transfer model. The use of the quartz-crystal microbalance is extended up to the Curie point (573 degrees C) by employing a dual resonator. Standing compressional waves, generated by a shear-mode quartz resonator in a liquid or by a compressional-mode quartz resonator in a gas, are used for sensing small changes in the composition of a liquid or gas, respectively.
