At the same time , the external microporous carbon shell can also efficiently trap guest Cr ( VI ) and prevent Fe / Fe3C nanoparticles from corrosion and subsequent leaching problem .
同时，外部微孔炭壳也可以有效地防止Fe/Fe3C纳米粒子的腐蚀和随后浸出问题。

The reaction stops until pH reaches the end of point 4.2.The XRD , element-analysis and TG are applied in the study to explore the dark substance in the process . The substance is considered as cementile ( Fe3C ), which is not generated in this process .
本文采用X射线衍射方法、元素分析和热重分析研究了工艺过程存在的黑色杂质，并做出了理论解释，认为黑色物质是炼钢工艺中的渗碳体（Fe3C），不是本工艺中产生的。
