%) and Al-28%Mg-14%Zn alloys used for thermal energy storage applications,such as the specific heat capacity including solid and liquid state;the mass density in the temperature range 30～500℃;the melting temperature and the latent heat of fusion.

We report the calculated results of the latent heat of fusion Δμ ls and the melting temperature T m as a function of cluster size.

Experimental instrument of measuring the melting heat of ice by electrothemal method;

The thermal properties of trans-ferulic acid such as melting point,melting heat,decomposition temperature,and so on,were studied by DSC and DTA-TGA.

According to the data of the melting heat of iron, the author corrected the solidus of FeC binary phase diagram in the rich iron end,and according to the corrected solidus e-valuated the carbon content at point H in 0.

The fusion heat and the degree of crystallinity of the various composites were got by DSC and XRD, which were related to the tribological performance.

The effects of natural convection and moving of solid PCM on melting heat transfer are compared.

In order to simulate the cooling of electronic devices by solid -liquid phase change materials (PCM ) the problem on two-dimensional melting heat transfer in a rectangularenclosure with discrete heat sources on one of its vertical walls has been solved numerically.
