dope composition meaning in English

纺丝液组分

The materials were characterized by room - temperature x - ray diffraction ( xrd ) , scanning electron microscopy ( sem ) and ac - impedance spectroscopy . firstly , the region of the single - phase , cubic - perovskite , the two - phase , cubic - perovskite and lasrgao4 or cubic - perovskite and lasrga3o7 , and the three - phase , cubic - perovskite and lasrgao4 and lasrga3o7 , shown in the region of the doped composition was determined from room - temperature xrd of the prepared materials
通过对所制备的材料进行xrd分析，在掺杂成分区作出了单相立方钙钛矿结构相区、两相(立方钙钛矿结构和lasrgao _ 4或者立方钙钛矿结构和lasrga _ 3o _ 7 )区以及三相(立方钙钛矿结构、 lasrgao _ 4和lasrga _ 3o _ 7 )区。
