近年来,几乎遍及全国的中小氮肥厂,不断进行改建、扩建,设计能力一翻再翻。为使生产过程稳定合理和经济运行,首先要提高生产中的成分分析水平。目前通用的奥氏分析法,周期长,误差大,远不能满足现代化生产管理的要求。多年来,许多人在色 In recent years, almost all over the country’s small and medium-sized nitrogen fertilizer plant, ongoing renovation, expansion, design capacity doubled. In order to make the production process stable and reasonable and economic operation, we must first increase the level of compositional analysis in production. The current common Austrian analysis, long cycle, error, far can not meet the requirements of modern production management. Over the years, many people are in color
