Description
(54) СПОСОБ СТАБИЛИЗАЦИИ АКУСТИЧЕСКОГО KOHTAICTA(54) METHOD FOR STABILIZING ACOUSTIC KOHTAICTA
После сн ти вибрации отсчет измер емого параыагр сигшла ведут не сразу, а через промежуток времени, равный времени, в течение которого снимаетс внутреннее напр жение в преобразователе.After the removal of the vibration, the measurement of the measured signal pairs is not conducted immediately, but after a period of time equal to the time during which the internal voltage is removed in the converter.
