acoustic impedance造句

seismic acoustic impedance log

Ultrasonic determination of carbon fiber composite porosity using acoustic impedance

Reflection coefficient changing of acoustic impedance interface during oilfield development

Instruments for the measurement of aural acoustic impedance/admittance

In consideration of the drawbacks in conventional acoustic impedance inversion method, the homotopy method with vast convergence was applied to the acoustic impedance inversion in seismic exploration.

The product of the velocity and density of a rock is termed in the acoustic impedance.

Code for measurement of sound-absorbing coefficient and specific acoustic impedance of standing-wave meter

opposition to the flow of sound through a surface; acoustic resistance is the real component of acoustic impedance and acoustic reactance is the imaginary component.

Methods to check on objective acoustic impedance and subjective pure tone audiometry.

In this paper, the acoustic impact testing method has been presented with two different excitation methods: the tap testing method and the acoustic impedance testing method.

The post-stack wavelet processing (estimate of determining reflectivity) is considered the first step to perform the acoustic impedance inversion.

Based on the numerical results, the curve-fitting expressions for the acoustic impedance of perforated plates with cross flow and grazing flow are obtained.

The proposed finite difference boundary condition expands the scope of application of FDTD to scattering problems of objects with a finite acoustic impedance but without tangential stress.

In geophysics, reflection refers to the seismic energy or signal that returns from an interface of contrasting acoustic impedance, known as a reflector, according to Snell's law.

For sandstone reservoir, the acoustic impedance of gas-bearing sandstone is lower than that of oil - and water-bearing sandstone, gas in reservoir may be directly recognized by using this difference.

In the process of applying this technology in one reservoir in the CN work area to forecast the oiliness, the results of this research and the results of acoustic impedance inversion have been reciprocally verified, showing that the multi-solution problem is well resolved.
