By further surface treatment by TiCl4 or O2 plasma, films with dif- ferent surface properties were obtained. It was found that treatment by TiCl4 plasma enhanced the amount of Ti3+ suiface state and Ti dislocation of the film, detected by the surface photovoltage spectroscopy, while O2 plasma surface treating enhanced its amount of O2 surface state. It was also indicated by the H2O adsorption experiment that film treated by O2 plasma had larger separation efficiency for photogenerated carriers than the one treated by TiCl4 plasma.展开更多

文摘目的 评价整合性心理护理干预措施对血液透析患者抑郁状态的影响.方法 采用贝克抑郁问卷（Beck Depression Rating scales）对血液透析治疗患者心理状况进行评估,了解其抑郁状态,并通过肾脏病生活质量短表（Kidney Disease Quality of Life Short Form,SKDQOL-SFTM）（1.3版）的第24个问题的回答情况对患者进行分层,A层为自我感觉获得医学支持较好的患者,B层为自我感觉获得医学支持较差的患者,然后对所有患者进行整合性心理护理干预,3个月后再度进行Beck评分,通过自身前后对照进行配对t检验,了解整合性心理护理干预前后患者抑郁状态的改善情况,通过独立样本t检验了解A、B两层患者抑郁状态的差别.结果 干预前B层患者的抑郁发生率较A层患者高（P〈0.05）,心理护理干预后两组患者的抑郁状态均有改善,但A、B两层患者进行整合性心理护理干预后抑郁状态的程度仍有差别.结论 整合性心理护理干预可改善血液透析治疗患者抑郁状态,但单纯心理护理干预和医学团队支持并不能完全解决患者的抑郁状态.
