Studies of Several Systems with Air Electrode Electro-Synthesizing H2O2 on the Spot for Degrading Aniline in Aqueous

A gas diffusion electrode (air electrode) with a high current efficiency of electro-synthesizing H2O2 using O2 in air was prepared. The several systems with air electrode as cathode of electro-synthesizing H2O2 on the reaction spot for degrading aniline in aqueous--electro-Fenton system, photo-excitation electro-H2O2 system and photo-electro-Fenton system, were developed. The rates of decomposition of H2O2 and mineralization of aniline were experimentally measured respectively under different conditions, and the results indicated there has an excellent parallel relation between decomposition rate of H2O2 and mineralization rate of aniline. Especially, photo-electro-Fenton system, where H2O2 is decomposed the fastest, is the best system of oxidizing and degrading organic toxicants. Compared photo-electro-Fenton system with photo-Fenton system, important role is revealed in the interface of air electrode. In this paper, the mineralization mechanism of aniline in the photo-electro-Fenton system was also discussed.

TiO2对合成渣中Fe2O3还原发泡过程的影响

研究了不同条件下TiO2和Fe2O3在合成渣中被碳还原时的发泡过程．计算了该发泡过程的发泡系数、消泡系数、平均发泡寿命、发泡强度和消泡过程开始的时间．用熔渣发泡参数定量地讨论了温度、TiO2加入量和初渣中TiC的含量对熔渣发泡过程的影响，发现当初渣中TiC的含量和TiO2加入量较多时，在发泡时会产生二次发泡现象．     

赵文鼎老师治疗女性更年期综合征的临床经验

更年期综合征是妇科常见病、多发病,此病严重影响了妇女的身心健康.本病肾虚为本,但往往会累及肝、心、脾及冲任之脉,在辨证时应谨守病机,通常变达,治疗时应补而不宜过于滋腻,用药轻灵平淡,泻火少用大苦大寒的栀子、龙胆草等,慎用重镇之品,滋阴勿寒凉,温阳勿干燥,灵活运用,同时,要善言开导,使病人心情舒畅,消除恐惧心理,生活要有规律,劳逸结合,才能取得较好的治疗效果.     

离子束改性对颗粒膜巨磁电阻效应的影响

用射频磁控溅射方法在Si/SiO2衬底上制备了(NiFeCo)36Ag64颗粒膜.用四探针法测量了注入Co离子前后(NiFeCo)36Ag64颗粒膜巨磁电阻效应的变化.用场发射扫描电镜分析了颗粒膜的形貌及成分.实验结果表明:注入Co离子对颗粒膜巨磁电阻有显著的影响,在相同退火温度下,注入离子可使GMR效应提高一倍以上.随着退火温度增加,颗粒膜巨磁电阻效应先增加而后减小,在360℃下退火可获得10.2%的最大室温巨磁电阻效应.
