For uniform mixing of seawater within the vertical column, techniques have been developed for the estimation of the effective attenuation coefficient of the system and the volume absorption coefficient, volume attenuation coefficient and volume scattering coefficient of the seawater by the data collected from tests.

Locus of reflectivity in complex coordinates during surface plasma resonance;

The results show that the reflectivity or amplitude versus incidence varies with the aspect ratio change under the condition of th.

Using an algorithm of neural networks,a deconvolution for seismic data can be made by iteration and, thereby, wavelet and reflectivity series can be get at the same time.

The effects on the reflectance of chiral materials by the constitutive parameters of helix;

In allusion to parameters of the model, made quantitative study on transformed wave offsets by introducing two methods of reflectance and elastic wave staggered.

By using a set of simple formula and calculating method with the rotating of coordinate axis, this paper gives the concrete expression of the reflectance and transmissivity of monopodium with discretional optical axis.

It leads to a conclusion that the reflection factor is a time dependent function.

Quasi-quantitative measuring principle of metallic film reflection factors, by means of Fabry-Perot interferometer is to be elaborated, with a few known reflection factors (R) tested and some ideas fully developed.

When the velocity proportion of longitudinal wave to transverse wave of a bed is distinctly different from that of another bed, the reflection factor will be changed with the variation of incident angle according to the elastic wave mechanics, which is the foundation of AVO theory.
