A new form of the sing-around technique for ultra-sonic velocity measurements

Новая форма техники для иэмерений сверхэвуковых скоростей

  • Published:
Il Nuovo Cimento B (1965-1970)

Summary

A new improvement of the sing-around technique for the measurement of the speed of ultra-sounds in liquids and solids is presented. This is accomplished by using a differentiation method in order to stabilize the trigger point of the singing pulse. Measurements of velocity in bidistilled water are carried out using this technique in order to evaluate its performance. Satisfactory results are obtained.

Riassunto

Si presenta un nuovo miglioramento della tecnica del sing-around per la misura della velocità degli ultrasuoni nei liquidi e nei solidi. Si è raggiunto il risultato usando un metodo di differenziazione per stabilizzare il punto di innesco dell’impulso sonoro. Si sono eseguite misure della velocità nell’acqua bidistillata con questa tecnica per valutarne l’efficienza. Si ottengono dei risultati soddisfacenti.

Реэюме

Предлагается новое усоверщенствование техники для иэмерения сверхэвуковых скоростей в жидкостях и твердых телах. Это усоверщенствование достигается эа счет испольэования дифференциального метода, для того чтобы стабилиэировать триггерную точку свистяшего импульса. Для оценки характеристик зтой техники с ее помошью проводятся иэмерения скорости в бидистиллированной воде. Получаются удовлетворительнеые реэультаты.
