测氧法 meaning in Chinese

oximetry

By contrasting the dimension and appearance of fe of different precursors , verified it is true that the dimension and appearance of precursor affect these facets of fe . modern measures , for instance xrd , tem , sem , laser and infrared technique etc . are used to research the technique indexes of sfp of fe , such as crystalline , dimensions and its distribution , shape and appearance , assemble status and its oxygen content
