Question

翻译一段英文论文的摘要

Strontium and magnesium doped lanthanum gallate, La09Sr01Ga08Mg0.2O2.85 (LSGM), and Ba-incorporated LSGM with compositions La0.9-xBaxSr0,1Ga0.8Mg0.2O2.85; x≤0.15 (LBSGM) were prepared by conventional solid state route. The X-ray diffraction patterns of the LBSGM system showed the main orthorhombic LSGM phases along with a few impure secondary phases. SEM micrographs exhibited fairly densed grain morphology of the system. The XPS spectra of the system indicated the presence of the constituent elements. It was found that sintered samples are stable in air and the constituent elements were found to exist in their characteristic valence states. The electrical conductivity of the LBSGM system was measured in the frequency range 20Hz to 1MHz and a temperature range of 300-800°C. The electrical conductivity of the system was found to increase slightly first up to x = 0.07 and thereafter it decreased for higher dopant concentrations. The formation of additional Ba-derived secondary phases in the compositions with x > 0.07 may lead to a decrease in electrical conductivity.不知道有没有错误，图片我也放上来了不要机翻。。。

Answer 1

锶和镁掺杂镓酸镧,La09Sr01Ga08Mg0.2O2.85(LSGM)和Ba-incorporated LSGM成分La0.9-xBaxSr0,1 ga0.8mg0.2o2.85;x≤0.15(LBSGM)是由传统的固态路线。LBSGM系统显示的x射线衍射模式主要斜方晶系的LSGM阶段以及一些不纯洁的第二阶段。SEM显微图显示出相当密集颗粒系统的形态。系统的XPS谱表示组成元素的存在。发现烧结样品在空气中是稳定的和组成元素被发现存在价态特征。的导电性LBSGM系统测量的频率范围20 hz 1 mhz的温度范围300 - 800°C。系统的导电性增加略首先发现了x = 0.07,此后为更高的掺杂剂浓度增大而减小。作品中的其他Ba-derived中学阶段的形成与x > 0.07可能导致电导率下降。
