In this paper we e- valuated that how the electric field affects the diffusion of vacancy and interstice ion, and drew a conclusion that this is the reason why Microwave can enhance the desitifaction, and further more pointed out that the shrinkage parallel to the direc- tion of electric field is larger than those other direction.

分析了微波对扩散的促进作用，进而指出在微波烧结中，相对于常规烧结，微波只是促进了平行于电场方向的致密化，在宏观上对于电场方向不随时间转向的偏振电磁波，应能观察到平行电场方向的收缩率大于垂直于电场方向的收缩率。

The results show that coal tar pitch and PMB can be used to synthesize COPNA resin, the reaction mechanism of which is a positive ion-typed condensation polymerization catalyzed by acid. There exist many micro fibers with a uniform distribution in the COPNA resin. The fibers grow with increase of modification time, and then intertwist and amalgamate. Moreover, the COPNA resin possesses good thermo-stability and high coke value.
