“longitudinal wave”造句，怎麼用longitudinal wave造句

The sensor was applied to detect several kinds of laser ultrasonic, such as surface acoustic wave, Lamb wave and longitudinal wave, well-defined waveforms were obtained.

A low frequency multi mode ultrasonic Lamb wave method suitable for characterizing shear and longitudinal wave velocities, thickness and density of ultra thin elastic layers is presented.

This paper deduces the errors sources from the process of ultrasonic longitudinal wave testing and evaluates its uncertainty.

Then the fitting relationships between the longitudinal wave velocity of rock masses and deformation moduli are established. Method of least square regression is used for deformation data processing.

The attenuation factor of longitudinal wave was changing linearly, whereas the attenuation factor of the slow shear wave kept nearly constant with a low frequency on the exploration seismic band.

Radial depth of plane flaw at the root of a weld can be quantitatively tested with a longitudinal wave probe assisted by a straight probe and receiving-transmitting straight probes.

The gliding longitudinal wave contains three parts, longitudinal wave beam, negative exponential gliding ivro-tational wave and positive exponential gliding irrotational wave.

In Zhenzhong Qu, longitudinal wave to the ground moving from top to bottom Britain.

The test results indicate that the above factors do not have much effect on ultrasonic longitudinal wave testing.

Theoretically, when gas exists in reservoir, longitudinal wave offset time will increase and transverse wave offset time will not change and density will decrease and neutron will decrease, too.

The result demonstrates that the twisting wave is longitudinal wave by anglicizing physical meaning of the longitudinal wave equation, transverse wave equation, and twisting wave equation.

The longitudinal wave cannot exist near the surface of a solid, and those exist near it are gliding irrotational waves.

A little apart from the surf ace, the longitudinal wave beam may exist and propagate parallel to the surface, yet has to connect with its corresponding gliding irrotational waves.

The experiment results indicted that there existed fairly good linearity between the grain sizes and longitudinal wave velocities when the measurements were done with 5p14z probe.

It is the gliding irrotational wave pair, not the longitudinal wave beam itself that excites longitudinal wave in mud to generate signal.
