分析仪器在继六十年代的跃进之后,从七十年代初期以来,又有了更大的发展。随着石油化学工业的发展以及冶金、造纸、制药和其他一些工业生产过程自动化水平的提高,要求新的控制方法对原料、半成品和成品的化学成份有更多、更精确的了解,并主要根据了解的成份量参数来调节和 After leaping in the 1960s, analytical instruments have seen even greater growth since the early 1970s. As the petrochemical industry develops and the automation of metallurgical, paper, pharmaceutical and other industrial processes increases, new control methods are required to have more and more accurate understanding of the chemical composition of raw materials, semi-finished products and finished products and are based mainly on Understand the ingredients of the parameters to adjust and
