Surface reconstructed SrTiO3 nanocrystals were synthesized by a thermal treatment process in presence of NaBH4 and SrTiO3 nanocrystals.The surface reconstruction of SrTiO3 nanocrystals is attributed to the introduction of surface oxygen vacancies or Ti sites (such as Ti3+ and Ti2+) during the hydrogenation treatment process.The light absorption and the charge transfer ability of SrTiO3 nanocrystals are simultaneously enhanced due to surface oxygen vacancies or Ti sites (such as Ti3+ and Ti2+),which are beneficial to photocatalytic water splitting.Meanwhile,these defects also change the redox potential of the photocatalysts.Since there existed a synergistic effect between the three,the ratio of hydrogen to oxygen production was also regulated.

TBM施工在国内已有20多年的历史,技术比较成熟,适用于15～25km中长距离、围岩状况较完整的中硬度岩石的隧洞工程,具有速度快、清洁环保、可有效降低隧洞施工对人体健康损害的优点,是未来长大深埋隧洞施工的首选工法.TBM施工及造价易受设备选型、围岩条件、渗漏水情况三方面因素的影响.设备选型可通过采购方案比选最大限度降低其对施工及造价的风险;TBM施工遭遇IV、V类围岩和渗漏水往往不可避免,而现阶段相关行业普遍对围岩类别变更、地下渗水量增加两个因素对造价影响的重视程度没有达到应有高度,招标文件相关条款约定普
