Abstract

The strength and hardness of dental stone were found to have better a correlation with porosity than with water-powder ratio. Within the range of porosity of less than 34 vol-%, the strength and hardness varied logarythmically with a linear change in porosity.

摘要

人们发现，牙科石膏的强度和硬度与孔隙率的相关性比与水粉比的相关性更好。在孔隙率小于34%（体积百分比）的范围内，强度和硬度随孔隙率的线性变化呈对数变化。
