用原位原子力显微镜研究了BaTiO_3单晶的电致疲劳裂纹和畴变现象。结果表明，交变电场作用下，畴变由周期性畴变变为随机畴变，正、负电场均能使止裂裂纹重新萌生。
Domain switching and electrically induced fatigue cracking in BaTiO3single crystal have been studied by in situ atomic force microscopy. The results show that an alternating electric field generates a random domain switching instead of a cyclic domain switching and an arrest crack is re-initiated by both positive and negative electric field.
