Предмет изобретени Subject invention
Способ измерени напр женности электрического пол с помощью помещаемого в измер емое поле твердого сегнетоэлектрика, свойства которого измен ютс под действием исследуемого пол , отличающийс тем, что, с целью повыщени точности измерени , значение напр женности электрического пол определ ют по изменению степени поглощени в сегнетоэлектрике ультразвуковых колебаний, возбужд емых с помощью установленного на нем излучател колебаний и воспринимаемых прие;мником этих колебаний, также установленным на поверхности того же сегнетоэлектрика.The method of measuring the electric field intensity by means of a solid ferroelectric placed in the measured field, whose properties change under the action of the field under study, characterized in that, in order to improve the measurement accuracy, the intensity value of the electric field is determined by the change in the degree of absorption in the ferroelectric ultrasonic oscillations excited by the oscillator mounted on it and perceived by the oscillator, also mounted on the surface of the same ferrite electrician.
Известные способы измерени напр женности электрического пол осуществл ютс с помощью помещаемого в измер емое поле твердого сегнетоэлектрика, свойства которого измен ютс под действием исследуемого пол .The known methods for measuring the strength of an electric field are carried out with the help of a solid ferroelectric placed in a measurable field, whose properties are changed by the action of the field under study.
В описываемом способе, основанном на использовании сегнетоэлектрика , помещенного в измер емом поле, значение электрического пол определ ют по изменению степени поглощени в сегнетоэлектрике ультразвуковых колебаний, возбуждаемых с помощью установленного на нем излучател колебаний и воспринимаемых приемником этих колебаний . Осуществление описываемого способа, согласно изобретению, обеспечивает в р де случаев повышение точности измерени .In the described method, based on the use of a ferroelectric placed in a measured field, the value of the electric field is determined by the change in the degree of absorption in the ferroelectric ultrasonic vibrations excited by the oscillator mounted on it and perceived by the receiver of these vibrations. The implementation of the described method according to the invention provides in a number of cases an increase in the measurement accuracy.
На чертеже изображена принципиальна схема изг«1ерени напр женности электрического пол , согласно описываемому способу.The drawing shows a schematic diagram of the circuit of the intensity of the electric field, according to the described method.
Как видно из схемы, в измер емое электрическое поле / помещают твердое тело 2, обладающее сегнетоэлектрическими свойствами, и возбуждают в нем ультразвуковые колебани с помощью излучател 3. Затем приемником 4 измер ют степень поглощени возбужденных колебаний в материале тела 2.As can be seen from the diagram, a solid 2 having ferroelectric properties is placed in the measured electric field / and ultrasonic vibrations are excited in it by means of the emitter 3. Then the receiver 4 measures the degree of absorption of the excited oscillations in the material of the body 2.
