简介:【摘要】:阳极效应是电解槽熔盐电解特有的现象,在电解铝生产过程中表现极为明显 。电解槽运行过程中,如果发生阳极效应,会造成电解槽电压急剧升高,达到2OV甚至60V以上,阳极效应的发生对整个电解系列影响很大,一是降低电流效率,影响电解各个技术指标;二是瞬时高峰值电压可能到达短路口上限阈值,击穿短路口,形成极大的安全隐患;并且,阳极效应发生时,造成电能消耗增大,氟化盐的挥发加剧,原材料损失增大等。本文针对铝电解槽发生阳极效应的机理以及其发生的利与弊展开分析,找出有力措施降低阳极效应系数。
简介: 【摘 要】目的:分析不同护理干预模式在静脉溶栓桥接动脉取栓治疗急性脑梗死患者中的应用对心理状况以及预后的影响。方法:将 110例静脉溶栓桥接动脉取栓治疗的急性脑梗死患者随机分成对照组( 55例)和研究组( 55例),分别行以常规护理、综合护理干预,对比两组心理状况以及预后。结果:经护理干预后,研究组 SAS评分、 SDS评分均明显低于对照组,且 Barthel指数高于对照组、 NIHSS评分低于对照组( P<0.05)。结论:针對静脉溶栓桥接动脉取栓治疗的急性脑梗死患者来说,采取综合护理干预可以有效改善患者心理状况,改善患者预后,临床价值显著。 【关键词】静脉溶栓桥接动脉取栓 ;急性脑梗死 ;不同护理干预模式 ;心理状况 ;预后 [Abstract] Objective: to analyze the influence of different nursing intervention modes on the psychological status and prognosis of patients with acute cerebral infarction treated by intravenous thrombolysis bridging artery thrombectomy. Methods: 110 patients with acute cerebral infarction were randomly divided into the control group (55 cases) and the study group (55 cases). Routine nursing and comprehensive nursing intervention were used to compare the psychological status and prognosis of the two groups. Results: after nursing intervention, SAS and SDS scores of the study group were significantly lower than those of the control group, and Barthel index was higher than that of the control group and NIHSS score was lower than that of the control group (P < 0.05). Conclusion: for the patients with acute cerebral infarction treated by intravenous thrombolysis and bridging artery thrombectomy, comprehensive nursing intervention can effectively improve the psychological status and prognosis of the patients, with significant clinical value.
