The dissertation is dedicated to the problems of choice of rational thermal mode of quartz resonator (QR) on the stage of oscillation fixing. The research proposes and investigates the complete dynamic model of multifrequency quartz oscillator (MQO), in which, for the first time, the temperature dynamic characteristics of quartz resonator are taken into account. The possibility of QR thermal mode regulation by means of MQO parameters variation to minimize the influence of thermodynamic characteristics of QR on the time fixing of multifrequency mode of oscillations is demonstrated.The optimization of heat–exchange processes quartz crystal sensor with modeled interelectrode clearance on the basis of worked-out algorithms and software is carried out. It proved the effectiveness of their use for reducing the time of fixing the thermal mode of resonator.
