nonstoichiometric meaning in Chinese
非化学计量
Examples
- Influences of nonstoichiometric ratio on the gas - sensing properties of sno2 - x thin films
薄膜非化学计量比对气敏性能的影响 - As a comparison , ba1 . 03ce0 . 8gd0 . 2o3 - was synthesized by sol - gel method . among these samples , nonstoichiometric samples were synthesized for the first time . the research work involved : the crystal phase of the sinters were determined by xrd ; ionic conduction under different experimental atmospheres was measured by gas concentration cells ; performances of hydrogen - air fuel cells with the sinters as electrolytes and porous pt as electrodes were measured
用粉末x射线衍射仪鉴定它们的结晶相；在( 600 1000 )范围内，以烧结体作为电解质隔膜，多孔性pt黑为正、负电极， pt - rh合金网为集电极，分别组成氢浓差电池、氧浓差电池及氢?空气燃料电池并测定了它们的性能，研究了不同气氛下样品的离子导电特性及影响燃料电池性能的因素。 - Surface states and the topmost surface atoms of the batio3 thin films have been analyzed by x - ray photoelectron spectroscopy ( xps ) and angle - resolved x - ray photoelectron spectroscopy ( arxps ) . the results show that the as - grown batio3 thin films have an enriched - bao nonstoichiometric surface layer which can be removed by ar + ion sputtering , and the atomic ratio of ba to ti decreases with increasing the depth of ar + ion sputtering
用x射线光电子能谱技术( xps )和角分辨x射线光电子能谱技术( arxps )研究了薄膜的表面化学态以及最顶层原子种类和分布状况,结果显示在热处理过程中薄膜表面形成一层富含bao的非计量钛氧化物层,并且钡-钛原子浓度比随着探测深度的增大而逐渐减小。
