The contents of hydroxy and bridge oxygen on the surface of TiO2 film have direct influences on the hydrophilicity. 表面羟基和表面桥氧的含量对TiO2薄膜的亲水性能均有直接影响。
The nature of the molecular orbitals and the electronic structure suggest that the tetrahedral [ WO4] site with single bridge oxygen is the most probable active center responsible for methane activation. 以单个桥氧担载的[WO4]四面体是最可能的甲烷活化中心。
Furthermore, an automatically balanced Wheatstone bridge circuit, which is necessary for O 2 ( 1 △) detection on the SOG of short operation period, is designed and tested by measuring the heat capacity of oxygen. 此外,还详细介绍了在短时间工作的SOG上进行O2(1△)绝对浓度测量所必须的自动平衡电桥装置,并通过氧气热容的测量检验了它的可靠性。
In the above m range the LiF also has the action of fracturing bridge oxygen as Li_2O, the F~-ions enter the network structure and phosphate groups containing F~-ions are formed, but the LiBr exists in free state. 在上述m范围内,LiF也和Li2O一样起断桥氧作用,F~-进入网络结构,生成含F~-的磷酸盐基团;LiBr则以游离形式存在。
By analyzing the IR spectrum, we found the reaction activity center is at bridge-oxygen atom. 通过红外谱图分析,发现二者的反应活性点处于多酸阴离子的桥氧上。
It is found that the bridge oxygen on is the most favorite trapping site of hole and the trapped hole orbital has the feature of the p orbital of O atom. 我们的计算表明表面的桥氧原子是空穴的最稳定俘获位,且空穴轨道具有。原子的p轨道的特征。
