| 1. | A variety of dilute mineral acids are used to extract the anions . 用各种稀的无机酸来萃取阴离子。 |
| 2. | Nitrosoguanidine crystallizes when the solution is cooled to 0℃ . 当萃取液冷却至0时,亚硝基胍结晶析出。 |
| 3. | Hence a variety of dilute mineral acids are used to extract the anions . 因此用各种稀的无机酸来萃取阴离子。 |
| 4. | The waxes are classed as alcohol or organic solvent extracted materials . 这种蜡质属于乙醇有机溶剂的萃取物。 |
| 5. | The waxes are classed as alcohol or organic solvent extracted materials . 这种蜡质属于乙醇或有机溶剂的萃取物。 |
| 6. | Solvent extraction is accomplished by the addition of an immiscible solvent to the wastewater . 溶剂萃取是向废水中投加不溶于水的溶剂。 |
| 7. | Such extraction modifies the whole cell-membrance network throughout the wool fiber . 这种萃取改变了整个毛纤维中所有细胞膜的网状结构。 |
| 8. | It is difficult to define the detection limits obtained by chelation-solvent extraction . 确定螯合--溶剂萃取法所得到的检测限颇为困难。 |
| 9. | In the u.s. much of the desolventized crude oil is degummed at the extraction plant . 在美国,多数脱溶原油,是在萃取加工厂内进行脱胶处理。 |
| 10. | Extraction of humic substances from sediments is often the first task that confronts the investigator . 从沉积物中萃取腐植物是研究工作者遇到的第一个问题。 |
