摘　　要：给出了多孔的金属氧化物半导体气敏晶体的既含晶粒间界传感作用又含晶粒缩颈传感作用的截面电导公式。又利用前文中所求得的Poisson方程的解 。The cross-section conductance formula,which contains the sensing function of grain-boundaries and grain-necks in porous metal oxide semiconductor gas sensing crystals,is proposed.On the basis of the solution of the Poission equation derived above, the best sensitivity crystal-grain dimension is proved by means of a combination of experiments and theoretical calculations.
