1·Through experimental study of technological plan, the result shows that reclamation rate of sulphuric acid is above 90% and ammonium sulfate is above 70%.
并对技术方案进行了试验研究，试验结果硫酸回收率达到90%以上，硫酸铵回收率达到70%以上。
2·Additionally the microorganisms must be supplied in the growth medium with nitrogen-containing compounds such as ammonium sulfate, ammonia, or urea, as well as with inorganic phosphates.
另外必须提供的微生物在与含氮如硫酸铵，氨水或尿素化合物生长介质，以及与无机磷酸盐。
3·The shelves, with water per acre of topdressing ammonium sulfate 10 kg or less, the use of urea, need appropriate reduction.
插架前，结合浇水每亩可追施硫酸铵10千克以下，使用尿素时，需酌情减量。
4·Ammonium sulfate deposition were used to get kidney bean phytohemagglutinin.
用硫酸铵沉淀法得到芸豆植物凝集素。
5·Through single factor test initially set up a suitable for duck solid fermentation medium optimization formula: plus accessories for the bran, and adding 1.5% ammonium sulfate.
通过单因素试验，初步确定适于鸭粪固体发酵的培养基优化配方为：外加辅料为麸皮，并加入1.5%硫酸铵。
