Owing to the higher sound-propagation velocity of water, ultrasonic waves
move faster between the two transducers.
t] ultrasonic wave
satisfy the wave-equations of (3) and (4) and have the forms:
Numerous studies have been investigated polymer processing using ultrasonic waves
The purpose of this study was to investigate whether ultrasonic wave
velocity varied with the MC of frozen and unfrozen spruce lumber.
Plaque grows in bacterial chains which cling to tooth enamel, but the ultrasonic wave
breaks these chains making them ineffective.
Because different defects interact differently with the ultrasonic wave
, each generates a "signature" reflected signal.
PERFLOWSort adopts non-droplet cell sorting method based on mechanical flow changeover instead of the common techniques including ultrasonic wave
and high-voltage charging which might do damage to living cells.
TEHRAN (FNA)- Iranian researchers produced a new catalyst that is able to decompose dye organic pollutants in the presence of ultrasonic waves
to purify the wastewater.
The 11 papers here consider such topics as photonic properties of non-crystalline solids, ultrasonic wave
transport in strongly scattering media, Anderson localization of ultrasound in three dimensions, time reversal focusing and the diffraction limit, and strongly correlated ultracold bosonic and fermionic quantum gases in optical lattices.
t] is the velocity of a transverse ultrasonic wave
which is determined by elastic coefficients.
The first sample is made form material without ultrasonic wave
treatment and the second one is made from material treated with ultrasonic waves
When polymer is present in the mold, a proportion of the incident ultrasonic wave
will be propagated in the polymer, and reflected from the next boundary to be encountered.
