Description
Предметом изобретени вл етс метод измерени «апр женности электрического пол .The subject of the invention is a method for measuring the "aprility of the electric field."
Диэлектрическа посто нна многих диэлектриков измен етс по величине в весьма широких пределах, Б зависимости от величины напр женности электрического пол , в котором диэлектрик находитс . Согласно изобретению, это свойство диэлектриков используетс дл измерени напр женности электрического пол . В измер емое поле ввод т (Конденсатор с обкладками, разделенными диэлектриком, обладающий значительной крутизной характеристики диэлектрической посто нной в зависимости от напр женности электрического пол . Следовательно, емкость такого .конденсатора будет функционально св зана с напр женностью исследуемого электрического пол . Если указанный измерительный конденсатор-зонд использовать в качестве элемента какой-либо колебательной цепи (контур, гетеродин и т. д.), то резонансна частэта этой цепи будет также известной функцией напр женности измер емого пол .The dielectric constant of many dielectrics varies in magnitude over very wide limits, B depending on the strength of the electric field in which the dielectric is located. According to the invention, this property of dielectrics is used to measure the strength of the electric field. The measured field is introduced (a capacitor with plates separated by a dielectric, having a significant steepness characteristic of the dielectric constant depending on the strength of the electric field. Consequently, the capacity of such a capacitor will be functionally related to the strength of the electric field under study. If the specified measuring capacitor - use the probe as an element of any oscillatory circuit (circuit, local oscillator, etc.), then the resonant part of this circuit will also be a known function the intensity of the measured sex.
В виде частного примера предлагаетс измерительна схема, состо ща из первого гетеродина, в контур которого включен выщеописа ный измерительный конденсатор-зонд, и второго гетеродина, стабилизированного по частоте. Колебани обоих гетеродинов подаютс на какой-либо нелинейный элемент, выдел ющий частоту биений; измерени частоты биений должны дать возможность контролировать напр женность исследуемого электрического пол .As a particular example, a measuring circuit is proposed consisting of a first local oscillator, in the circuit of which a test probe capacitor is included, and a second local oscillator that is frequency stabilized. The oscillations of both local oscillators are applied to a non-linear element that extracts the beat frequency; measurements of the frequency of the beats should make it possible to control the intensity of the electric field under study.
