铬

However, Co-Cr alloy will be under various chemical and even electro-chemical reactions with surrounding materials while used in the complicated and relatively chemical active oral environment. The released metallic ions, generated from the consequent corrosions, not only affect the designed material properties, but also have negative effect on human body at different degree.

One gram of Cu-saturated selective ion exchange resin was horizontally embedded in saturated soil pastes and recovered after various time ( 1、2、3、4 days) intervals, and the amounts of Cr adsorbed on the ion exchange resin were measured in order to determine the time needed for equilibrium.

将装有铜饱和树脂(DOWEX M4195)之树脂袋埋入已制备好之水饱和土壤中，分别於1、2、3及4天后取出树脂，振荡后测定树脂抽出土壤中有效性六价铬之含量，以确定抽出水田土壤中有效性六价铬所需平衡之时间。

Through the research of the hereditary mechanism of needle-like carbide, it was found that the same structures were also found in the low chromium cast iron when there was needle-like carbide in the primary material. In particular, the hereditary effect of needle-like carbide in low chromium cast iron were most obvious when primary material was the complete chill pig iron or the returns.
