When the acoustic waves that make sound cause the fibres to vibrate it produces a corresponding electrical signal that can be detected.
In four locations where a sunspot was soon to emerge, acoustic waves returned to the solar surface with anomalous rapidity —more than a dozen seconds faster than normal.
Thus, acoustic waves retain more of their energy when they reflect off the ground.
The acoustic wave propagation in one dimension photonic crystal with defects was studied by eigen matrix method.
Array acoustic wave data are widely applied in well logging evaluation due to its abundant stratigraphic information.
In this paper some parameters of the plasma are measured by means of the acoustic waves produced by the interaction between high power laser and target materials.
A pulse acoustic wave and its relationship with OAO flurescence are recorded.
In chapter two, the small but infinite amplitude dust acoustic wave (DAW) in a collisionless, unmagnetized two-ion-temperature cold dusty plasma has been studied.
化学吸附敏感膜是声表面波 (SAW) 气体传感器的关键组成部分。
Chemical sensing film is the key component of surface acoustic wave (SAW) gas sensor.
Piezoelectric ceramic is used widely for ultrasonic surface Acoustic wave touch screen.
