中文摘要：

为同时研究取向硅钢中纳米级MnS析出物的形貌及其分布特征,本文在非水溶剂选择性恒电位电解侵蚀法的基础上提出采用恒电压电解侵蚀法,既简化了实验装置,又取得良好实验效果,为取向硅钢抑制剂行为研究提供了一种更便捷的实验手段。

英文摘要：

For study the morphology and distribution of MnS in grain-oriented silicon steel,in the same time,the non-aqueous constant electrolyte-voltage etching method was proposed based on the non-aqueous constant electrolyte-potentiostatic etching method in present paper.It is not only made the experimental set-up sample,but also achieved good results as a more convenient experimental method for studying the inhabitation in grain-orientation silicon steel.
