Three phases were formed by adding ammonium sulphate and t-butanol into the slurry of rice bran and water. 在稳定化米糠和水的悬浮液中加入硫酸铵(E517)和叔丁醇可以形成三相。
These mines supply the raw material for making ammonium sulphate. 这些矿提供了制造了硫酸氨的原抖。
More ammonium sulphate solution is being recovered in the process of distilling oil shale. 在提炼油页岩的过程中回收的硫酸铵(E517)液比过去多了。
Calculate the percentage by mass of nitrogen in urea and ammonium sulphate. 试计算氮在尿素及硫酸氨的质量百分率。
An antagonistic substance produced by A30 was purified by ammonium sulphate precipitation, FPLC and HPLC and named P1. A30菌株培养液经硫酸铵(E517)沉淀、FPLC疏水色谱、HPLC反相色谱后,纯化得到一种拮抗活性物质,命名为P1。
