More ammonium sulphate solution is being recovered in the process of distilling oil shale.(在提煉油頁巖的過程中回收的硫酸銨液比過去多了。)

What the prospectors found at Mountain Pass was an igneous ore containing mainly carbonate, sulphate and silicate phases.(勘礦工人們在帕斯山發(fā)現(xiàn)的礦石標(biāo)本是火山熔巖，其主要成分是碳酸鹽、硫酸鹽和硅酸鹽。)

The better baking condition is reached for reclamation of sulphate when the rate of volatilization is 12~18%.(在揮發(fā)量為12～18%時(shí)，是得到較好硫酸鹽實(shí)收率的焙燒條件。)

Adding sulphate to the solution will give a precipitate.(將硫酸鹽加入該溶液會(huì)產(chǎn)生沉淀。)

Injecting sulphate particles into the stratosphere, for instance, would cool the Earth by reflecting more sunlight into space.(向平流層噴灑硫酸鹽顆粒，可以通過反射陽光達(dá)到降低地球溫度的作用。)

What color is copper sulphate solution?(硫酸銅溶液是什么顏色？)

Sulphate particles, meanwhile, survive only a few years in the atmosphere.(而硫酸鹽微粒方案只能在短暫的幾年內(nèi)有效。)

Volcanoes inject sulphur dioxide into the stratosphere, where it eventually forms small particles of sulphate that reflect sunlight back into space.(當(dāng)火山噴發(fā)出的二氧化硫到達(dá)平流層，就會(huì)在那里形成硫酸微粒，可以把太陽光線反射回太空。)

The reclamation of sulphate and output of vola-tirnatter in baking have been researched.(研究了焙燒時(shí)硫酸鹽的實(shí)收率和揮發(fā)分的排出量。)

Chemical wood pulp, soda or sulphate, other than dissolving grades.(堿木漿或硫酸鹽木漿，但溶解級(jí)的除外。)
