     Based on investigating the partially molten products, the authors calculated the vp of bojite at different pressures and temperatures with volume percentages and elastic parameters of minerals and melt. The calculations show the same vp-t correlations with experiment runs, which indicate that at first vp decreases slowly with increasing temperature, and then decreases quickly above about 800℃ to 900℃ at different pressures. The investigations of the products indicate that bojite is dehydrated and partially molten when the temperature is higher than 812℃ at 0.6 GPa, 865℃ at 1.0 GPa and 919℃ at 2.0 GPa respectively. It is believed that partial melting is responsible for quick decrease of vp at high temperature. There is more quick decrease of vp of bojite when volume percentages of melt are lower than about 2%.
