Description
мощью приемного пьезопреобразовател 7 и подаютс на вертикальный усилитель 6 электронного осциллографа 5, развертка которого синхронизуетс задающим генератором 2.by the power of the piezoelectric transducer 7 and fed to the vertical amplifier 6 of the electronic oscilloscope 5, the sweep of which is synchronized by the master oscillator 2.
Перестройкой генератора достигаетс полна согласованность пр мого частотно-манипулированного сигнала с многократно отраженной волной на одной из двух частот манипул ции , что находит отражение на экране осциллографа 5 в виде максимума сигнала. Дисперси скорости ультразвука определ етс по измеренным значени м скоростей ультразвука на частотах манипул ции.By tuning the oscillator, full consistency of the direct frequency-manipulated signal is achieved with a multiply reflected wave at one of the two manipulation frequencies, which is reflected on the screen of the oscilloscope 5 as a signal maximum. The dispersion of the ultrasound velocity is determined from the measured values of the ultrasound velocity at the frequencies of manipulation.
