The results shown that both [Cu_2]~2+ and NR molecular can intercalates into the DNA double helix layer, and there is a competition between these two interactions. Furthermore, chemometrics approach, parallel factor analysis, was used to resolve the measured three-way CW-SFS data, which provided simultaneously the concentration information for the three reaction components, NR, [Cu_2]~2+ and NR-DNA, for the system at each equilibrium point. This PARAFAC analysis indicated that the intercalation of the [Cu_2]~2+ molecule into the DNA proceeds by exchanging with the NR probe, and can be attributed to two parallel reactions.

A new 3D human face model is put forward in this paper after some characters of the human face and the muscle tissues on the face are researched and some actions of the facial expression are analyzed. In this model we divide the whole face into some parts according to its structure. To each part, we apply the principle of elastomer metamorphosing to our face model, so a specific face model can be easily gotten by modifying a common face model.
