The low temperature thermodynamics of the stable phase of silver was assessed by the polynomial model and Debye model from the experimental data available in the literature. By means of the constrained non-linear least squares curve fitting arithmetic, two sets of parameter values were determined. The expression of the thermodynamic functions cp(T) and G(T)-H (298.15K) at 0-298.15K were presented. Only the low temperature thermodynamics of the metastable phase of silver can be extrapolated by the Debye model. The expression of the thermodynamic functions cp(T) at 0-298.15K was presented.

On the basis of energy and shape method for the determination of the valence bond (VB) structures of crystal, the valence bond
structure of titanium is redetermined at room temperature and calculated in the whole temperature range of 0-1943K. The outer
shell electronic distribution of Ti is ec2.9907 · (sc0.4980 + dc2.4927) ef1.0093 in crystal. The temperature dependences of the VB structures of hcp and bcc phases are the same. The VB structures of hcp and bcc phases monotonically increase or decrease with the increase in temperature, but show discontinuous changes at the phase-transformation temperature 1155K.
