Известные устройства дл  исследовани  частотных спектров кварцевых пластин не позвол ют определ ть непрерывные спектры.The prior art devices for studying the frequency spectra of quartz plates do not allow the determination of continuous spectra.

В описываемом устройстве дл  исследовани  частотных спектров кварцевых пластин определение непрерывных спектров, особенно при многоволнистости кварцев , достигнуто тем, что исследуема  кварцева  пластинка включена кеос плечо Б мостиковую схему, остальные плечи которой образованы анодными сопротивлени ми двухтактной ступени, питаемой напр жением качающейс  частоты, и емкостью нейтрализующего конденсатора.In the described device for studying the frequency spectra of quartz plates, the determination of continuous spectra, especially when quartz is multi-wavelength, is achieved by the fact that the quartz plate under study turns on the keos shoulder B bridge circuit, the remaining arms of which are formed by the anode resistances of a push-pull stage fed by voltage sweep and capacitance neutralizing capacitor.

На чертеже изобрааена принципиальна  электрическа  схема предлагаемого устройства.In the drawing, the circuit diagram of the proposed device is shown in principle.

Двухтактна  ступень выходной части устройства выполнена на лампах I и 2,к сеткам 3-4 которых подводитс  напр жение качающейс  частоты посто нной амплитуды от генератора. Анодные сопротивлени  6 и 5, нейтрализующий конденсатор 7 и кварцева  пластинка 8 образуют соответствующие плечи измерительного uocia. Набор сопротивлений 9,10 и II, включенных параллельно кварцевой пластинке В, служит дл  регулировки чувствительности измерительногоThe two-stroke stage of the output part of the device is made on lamps I and 2, to the grids 3-4 of which the voltage of the oscillating frequency of a constant amplitude from the generator is supplied. The anode resistances 6 and 5, the neutralizing capacitor 7 and the quartz plate 8 form the corresponding shoulders of the measuring uocia. A set of resistances 9, 10 and II, connected in parallel to the quartz plate B, serves to adjust the sensitivity of the measuring
