extraction n. 1.抽出,拔出。 2.【化学】提取(法);萃取(法);回收物,提出物;精炼。 3.精选,摘要。 4.血统,家世,出身。 5.【数学】开方,求根。 spirit of the first extraction 原汁酒。 a man of foreign extraction 外国(血统的)人。 extractions from a book 一本书的内容摘录。 an extraction of 81 percent 百分之八十一的出粉率,八一粉。 the extraction of root 【数学】开方法,求根法。
The recovery of the extraction agent can reach 85 % 萃取剂回收利用率可达85 % 。
We use different extraction agent in the manufacturing and we can provide low lincomycin b with different content on demand . this is one of our strong advantage on quality 生产采用不同于其他厂家的萃取剂,可根据客户需求生产不同含量的低b组份林可霉素,具有很强的质量优势。
Abstract : the chromium leaching - out toxicity was determined with different extraction agents , different extracting time , different solid - liquid rate and different extracting method . in accordance with petroleum drilling engineering and protecting environment , a test method suited to evaluate the leaching - out toxicity of waste drilling mud was suggested 文摘:以铬为分析指标,探讨了钻井废弃泥浆在不同的提取剂、不同的提取时间、不同的固液比以及不同的提取方式下铬的浸出毒性大小,提出了适合评价钻井废弃泥浆中铬的浸出毒性的试验方法。
