residue term

It shows that this industry plot of soil really exists the heavy metals pollution and the heavy metals Cr particularly supers mark severely, which has something to do with the long-term pilling-up waste residue that contains Cr and letting out wastewater that contains Cr.

说明该工业用地土壤确实存在重金属污染，尤其是重金属Cr超标严重，这与该地块长期堆放含铬浸出渣和排放含铬废水有关。

Long age strength test shows that different mineral admixture doped has different effects to the early strength and long-term strength of soda residue stabilize stone chips, single-doped slag powder is favorable to the early strength, and slag and fly ash mixed is favorable to long-term strength.

长龄期强度试验结果表明，掺不同矿物掺和料对水泥-碱渣稳定石屑的早期强度与长期强度有不同的影响，掺矿渣微粉对早期强度有利，掺矿渣微粉和粉煤灰对长期强度有利。

The vacuum residue system cannot guarantee long term running without fouling due to oil residue.
