Abstract
Изобретение относитс к измерительной технике и может быть использовано при акустических исследовани х конденсированных систем при низких и сверхнизких температурах импульсными методами. Цель изобретени - расширение области применени за счет снижени нижнего температурного предела измерений вследствие уменьшени выделени тепла в процессе излучени ультразвука. Достижение положительного эффекта осуществл етс за счет применени известного метода наложени эхо-импульсов в варианте излучени одиночного импульса. Лини 6 переменной задержки позвол ет выбирать начало отсчета на временной развертке, а генератор 7 парных импульсов позвол ет точно измер ть врем между импульсами и выбирать дл измерени любой эхо-импульс. Использование запоминающего осциллографа 5 в режиме накоплени позвол ет рассматривать в увеличенном масштабе отдельные участки выбранной пары эхо-импульсов. 2 ил.The invention relates to a measurement technique and can be used in acoustic studies of condensed systems at low and ultra low temperatures by pulsed methods. The purpose of the invention is to expand the field of application by reducing the lower temperature limit of measurements due to a decrease in heat generation during the process of ultrasound emission. Achieving a positive effect is accomplished by applying the well-known method of applying echo pulses in a single pulse radiation variant. The variable delay line 6 allows you to select the origin on the time base, and the pair of pulses generator 7 allows you to accurately measure the time between pulses and select any echo pulse for measurement. The use of the storage oscilloscope 5 in the accumulation mode makes it possible to view on an enlarged scale separate portions of the selected pair of echo pulses. 2 Il.
