Halo phenomena in nuclei are driving forces for the development of the physics with radioactive ion beams. They are threshold effects and have been first observed in the weakly bound system *** that most open shell nuclei are deformed,the interplay between deformation and weak binding raises interesting questions,such as whether or not there exist halos in deformed nuclei and,if yes,what are their new features. In order to describe adequately the halo phenomena in deformed nuclei,contributions of the halo,deformation effects,and large spatial extensions of these systems should be considered in a fully self-consistent way.A deformed relativistic Hartree Bogoliubov（DRHB） theory has been developed in which the DRHB equations are solved in a spherical Woods-Saxon basis with the proper asymptotic behavior at large distance from the nuclear center.

The phase inversion emulsification technique (PIET) is an effective physical method for preparing waterborne dispersions of polymer resins. Some results concerning the preparation of bisphenol A epoxy resin waterborne dispersions by PIET in our laboratory were summarized. Electrical properties, rheological behavior and morphological evolution during phase inversion progress were systematically characterized. The effects of the emulsifier concentration and emulsification temperature on phase inversion progress and the structural features of the waterborne particles were studied as well. The deformation and break up of water drops in a shear field were analyzed in terms of micro-theology, while the interaction and coalescence dynamics of water drops were discussed in terms of DLVO theory and Smoluchowski effective collision theory, respectively. Based on the experimental results and theoretical analysis, a physical model of phase inversion progress was suggested, by which the effects of the parameters on phase inversion progress and the structural features of the waterborne particles were interpreted and predicted.
