Comparing with water, the optimal heat transfer enhancement is achieved near the critical micelle concentrations of surfactants. The degree of heat transfer enhancement is different with different surfactants and is influenced by solubility characteristic, ionic nature and chemical structure of surfactants. Boiling in surfactant solutions, when compared with that in water, is observed to be more vigorous with smaller-sized, more regularly shaped and faster departure frequency bubbles, but the surfactant solutions of Triton X-100 and Triton X-114 become cloudy for the cloud point of surfactants.

The completely diagonalized Hamiltonian matrices of 3d2/3d8 ion configuration in the trigonal symmetry have been established by irreducible representation method. Taken into account the influence of the spin-spin coupling interactions omitted in previous publications, the spectra and the constants of crystal structure and zero-field splitting parameters of CsNiCl3 crystal and CsNiCl3: Mg2+ crystal are calculated and the influence of the doping to the spectra, the constants of crystal structure, zero-field splitting parameters and Jahn-Teller effect are studied. The results show that doping can change the structure of crystal which brings about the changes in the spectra and zero-field splitting parameters as well as Jahn-Teller effect.
