It was demonstrated that the values of domain strain decreased while the rate in reduction of the domain strain lowered with larger n. combined the xrd with sem results, the non - fracture mechanism of the sample when pure electric fatigue was applied can be described as : at an earlier stage of electric fatigue, the high repeated incompatible strain led the major fracture mode for the fatigued sample to be of inter - granular. the ability of domain switching in a - - > c of the sample along with the direction of an applied electric field kept dropping, hence, reduced the domain strain
結合xrd和sem觀測，提出了純電疲勞作用下試樣不會發生斷裂的機理：電疲勞初始階段，試樣中的非協調高應變導致沿晶微裂紋，隨著微裂紋的增加，使得試樣沿外電場方向發生a c疇的能力不斷降低，從而導致疇變應變減小，當應變減小到一定程度時，將不足以在試樣中引起新的微裂紋或使原有微裂紋繼續伸長。 -
