Description
Horo ПОЛЯ проход т параллельно плоскости пленочного проводника и перпендикул рно его оси. Такое расположение резонатора в магнитном поле дает возможность получить относительное изменение частоты резонатора до дес тых долей процента. Благодар взаимодействию тока, протекающего через контур, с магнитным полем на резонатор действует крут щий момент.Horo FIELDS run parallel to the plane of the film conductor and perpendicular to its axis. Such an arrangement of the resonator in a magnetic field makes it possible to obtain a relative change in the frequency of the resonator up to tenths of a percent. Due to the interaction of the current flowing through the circuit with a magnetic field, a torque acts on the resonator.
Величина усили , действующего на резонатор , пропорциональна величине тока, протекающего через контур и индукции магнитного пол . Перестройка частоты происходит в результате изменени момента инерции резонатора.The magnitude of the force acting on the resonator is proportional to the magnitude of the current flowing through the circuit and the induction of the magnetic field. The frequency tuning occurs as a result of a change in the inertia moment of the resonator.
Благодар высокой упругости кварца и отсутствию остаточных деформаций за счет быстрого изменени тока, протекающе-го через контур, достигаютс высока точность и быстродействие управлени . ,Due to the high elasticity of quartz and the absence of residual deformations due to the rapid change in the current flowing through the circuit, high control accuracy and speed are achieved. ,
Таким образом, нанесение на поверхность резонатора токопровод щего контура из немагнитного материала с высокой электропроводностью и помещение резонатора в однородное поле посто нного магнита так, чтоThus, the deposition of a conducting contour of a nonmagnetic material with high electrical conductivity on the surface of the resonator and the placement of the resonator in a uniform field of a permanent magnet so that
силовые линии магнитного пол проход т параллельнд плоскости токопровод щего контура и неперпендикул рно его оси, позвол ет увеличить точность и быстродействие управлени .The magnetic field lines passing parallel to the plane of the conductive loop and non-perpendicular to its axis, allows to increase the accuracy and speed of control.
