  new phase

A solution to this system allows one to find the surface tension of new phase nucleus of any size (including minimal) and any sign of surface curvature.

The calculation of the formation work of a new phase with account of both the thermodynamic parameters and stress state makes it possible to estimate the probability of the formation of precipitates on grain boundaries depending on their orientation.

The calculation of the formation work of a new phase with account of both the thermodynamic parameters and stress state makes it possible to estimate the probability of the formation of precipitates on grain boundaries depending on their orientation.

At a molar nonionic surfactant/protein ratio in the range of 6-10, the additional binding of Tween 80 molecules by the particles of the new phase due to hydrophobic interactions is observed.

Allowance is made for the influence of surface tension, which plays a critical part in the formation of nucleating centers of a new phase [2].

The characteristics of TFM signal are determined by its phase function. A new phase function which meets the requirments of TFM and makes the recovery of carrier and clock easier is presented in this paper. Then, the performance of TFM system using a multi-level decision method following a frequency discriminator is analysed. Finally, according to the properties of TFM signal, a new timing circuit is proposed.

An improved method involving three optical phase conjugators for measuring the phase of complex third-order nonlinear susceptibility (χ(3) ) directly has been developed. The χ(3)'s phases of two saturable absorption dye-doped polymers, i. e.,Eosin Y/polyvinyl alcohol (Eo/PVA ) and Erythrosin B/polyvinyl acohol (Er/PVA)have been measured by using this method. We found that their χ(3)'s phases originating from saturable absorption effect has a tendency approaching to - π from -π/2 as the wavelength used goes far...

An improved method involving three optical phase conjugators for measuring the phase of complex third-order nonlinear susceptibility (χ(3) ) directly has been developed. The χ(3)'s phases of two saturable absorption dye-doped polymers, i. e.,Eosin Y/polyvinyl alcohol (Eo/PVA ) and Erythrosin B/polyvinyl acohol (Er/PVA)have been measured by using this method. We found that their χ(3)'s phases originating from saturable absorption effect has a tendency approaching to - π from -π/2 as the wavelength used goes far away from the absorption peak. Otherwise, χ(3)'s phase originating from dye-bleached effect was about-17/18π.
