The maximum nitrogen concentration was about 14 times its bulk level for the steel containing 0.28 % N; 含氮量越高,氮在钝化膜中的富集程度越大,对于含0.28%N的钢,其最高富集系数可达14;
In the ELISA test, the expression of antibody part is not high, but the expression of interferon has been reached nanogram ( 10-9g ) level, the maximum reached 9ng / ml, the concentration of the general role of interferon only picogram ( 10-12g ) level. 经ELISA检测,抗体部分的表达量不高,但干扰素的表达却已经达到了纳克(10-9g)级,最高已达9ng/ml,而一般干扰素的作用浓度只需皮克(10-12g)级。
