Abstract: The way to calculate the micro-pore-size distribution measured by Bubble-Point method was improved on the basis of the existent Graphical Solution. The new way avoids the complexity in the process of Graphical Solution, and can directly adopt the data measured in experiments to caJculate the pore-size distribution. Due to considered gas expansion effect, it makes the calculation most likely represent the real situation, and it can be easily processed by computers.

Key words: porous ceramics, bubble-point method, pore-size distritution, calculating way
