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.

Study on characteristic of the absorption and scattering coefficients of Taihu Lake waters;

The results indicate that the mean value of the scattering coefficient was (850.

Through the observing system of water inherent optical properties,which were developed by WETlabs Inc,the backscattering and scattering coefficients of Lake Taihu had been obtained in Oct.

The plane wave algorithm was employed to calculate the band gap structures of two-dimensional aluminum alloy / air phononic crystals with three different shapes of scatterers.

This paper caculated physical parameters of a single scatterer in ideal condition(displacement and stress are continual),deducing the specific expressions of elements in the T matrix for cylinder scatterer and the equations to compute the scattering cross section.
