Study on the Corrosive Effect of Sediment on Carbon Steel

摘要: 本文对银杏叶用不同浓度乙醇溶液热浸和冷浸两种方法进行了提取黄酮类化合物的试验，结果表明热浸６０％乙醇为溶剂、冷浸７０％乙醇为溶剂时浸取效果最佳。

Abstract: This paper studies the corrosive effects of CaCO 3(A,R),BaCO 3(C,R),Fe 2O 3(A,R),Saponite (C,R),Fe 3O 4(C,R) and filting residue ,etc.on A 3 carbon steel through measuring their self-corrosion electrical potential and couple current of sediment.
