监舍外墙内侧墙面霉斑的处理方法

<正> 由于新疆冬季寒冷,气温低,室内外温差大,房屋建筑外墙、拐角处(构造柱位置)普遍存在容易形成结露和霉斑等现象。特别是看守所监舍建筑更为突出,由于室内相应居住人员多、湿度大,通风换气量小,在监舍内墙面上往往会形成大面积的结露,在冬季供暖期间(室内平均温度可达18℃以上时),内墙面上逐渐呈霉点直致蔓延到房间的整个内墙面,甚至出现部分内墙面粉抹层膨胀、开裂、脱落的现象,针对这种情况,通过现场实地观察,我们从两方面入手,一是采取提高暖气温度,二是加大通风换气措施,这样实施一段情况后,收效甚微,经过分析,我们认为,由于监舍的自身的使用特点,室内湿度大,而进入冬季室内外温差较大,极易在内墙面上聚生霉斑,虽然我们采取了以上措施,未阻止霉斑的产生,只能说明墙体保温是应重点解决的问题。     

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.     

船舶坐墩墩反力的分析计算

剖析了传统的船舶坐墩反力计算方法，并用有限元法进行了对比分析计算，指出了前者存在着适应范围的局限性和计算结果不完整及不直观等问题，认为采用有限元法进行船舶坐墩墩反力分析计算较适宜。最后讨论了墩木刚性对船体结构安全性的影响，提出了墩木设置的一般原则。
