We describe a novel method to enrich isotopes and isomers via magnetic deflection of optically polarized atomic beam. High electronic polarization with opposite signs for atoms o'f both isotopes respectively is achieved by selective optical pumping using lasers with different frequencies and polarizations and then the isotopes are enriched by deflecting the oppositely polarized isotopes along different directions by the inhomo-geneous magnetic field in the spin selective magnet. Separation selectivity and throughput are evaluated and the advantages, disadvantages and prospects of possible application of the present method are discussed in comparison with other existing methods.

The Polanyi-Dubinin equation was used to predict adsorption isotherms for eight organic vapors at 25℃ and for two organic vapors at 25℃, 40℃ and 60℃ on activated carbon in this analysis. The theoretical affinity coefficient, β, was calculated by three methods(molar volume, molecular parachor and electronic polarization) based on nonpolar and polar reference vapors. The corresponding experimental isotherm data were measured by gravimetric method. A comparison between calculated and measured isotherm data showed that ( 1 ) for optimum isotherm prediction, the reference vapor should be similar in polarity to the vapor whose adsorption is to be predicted, ( 2 ) after choosing an appropriate reference vapor, there is essentially no difference in the accuracy of the isotherm predictions by the three methods, ( 3 )the molar volume mth-od is more applicable for predicting isotherms at different temperatures.

Abstract In view of the nonlinear property of the electronic polarization curve, a MWR pattern for its electric potential distribution evaluation is studied. The results of potential distribution are given when the metal's electrochemistry corrosion occurs in the corrosive medium by means of the boundary disposition method, which coincides with the results by experiment and the BEM. It shows the validity of MWR for nonlinear boundary value problems.
