| Abstract: | According thermodynamics analyzing and calculating, it was discussed under the volume via center stack that the effects of expanding and shrinking mechanism about Huadong sintering model on the changing of general surface energy, and the conclusion was given that shrinking mechanism basically plays leading role in the whole sintering process. In detail, the paper focuses on two kinds of the volume via center stack, which are the equi-radius sphere and the symmetric inequi-radius sphere. |
