电生H2O2协同电解絮凝法处理餐饮废水实验研究

采用电生H2O2协同电解絮凝法处理餐饮废水，研究了废水初始浓度、电解时间、电压、电极材料、pH等因素对降解餐饮废水的影响．结果表明，进水CODCr在1200mg／L以内、pH值为中性的餐饮废水，在10V电压、电磁搅拌、曝气条件下，电解15min后，COD去除率在80％以上．该法利用了铝阳极反应生成的絮凝剂Al(OH)3和阴极上电合成的H2O2对有机物的去除作用，同时阳极产生的H^ 与阴极产生的OH^-中和又促进了两极的反应，使有机物降解更彻底．

根据西安地区原型摩擦桩基的地层特点和土性条件,运用有限元基础理论,依据相应的边界条件与假设条件建立单桩、两桩、四桩的数学模型,得出单桩、桩群的沉降与土的共同作用的影响因素,对黄土地区单桩桩土相互作用和群桩效应的机理进行了研究.     

突显公正原则量化法律责任——读《电力监管条例》

《电力监管条例》旨在规范电力监管行为，只有规范才能公正，规范是执法的前提，也是执法的宗旨，没有规范，就没有政策与秩序。《电力监管条例》体现了公正性宗旨，其实施必将推进和规范电力的商业化运营。电力行业协会应充分利用公正的立场，发挥行业协会特殊的中介作用和协调功能，配合电力监管机构宣传、贯彻、执行好《电力监管条例》。[编者按]     

市场五大因素对电力的影响

置身于市场经济大背景下的电力市场化改革，既受电力经济自身特性与电力生产固有特点的制约，也受市场经济五大因素的左右。政府作用、企业权利与行为、投入要素的成本与价格、贸易环境、金融参数这市场经济五大因素在西方被称为：政府行为规范化、经济主体自由化、生产要素市场化、贸易环境公平化、金融参数合理化。分析并采取措施应对市场经济五大因素对电力市场的影响，有助于电力行业处变不惊，把握电力市场化改革主动权，推进电力市场建设，提升经济效益，坚持可持续发展。

溴化锂吸收式制冷机维修特例

蒸汽双效型演化锂吸收式冷水机组是一种应用普遍的机组。它是以蒸汽为驱动热源，溴化锂溶液为吸收剂、水为制冷剂而制取工艺或空调用冷水的设备，冷水机组的高真空度是保证机组正常运行的必要条件，下面将我们耐某机组维修时碰到的一起特殊故障处理过程进行分析，希望对从事空调运行和维护的同行有一定的参考借鉴作用。     

A New Design of Magnetic Fluid Seal for Liquids

Direct contract between the sealed liquid and the magnetic fluid in a dynamic system under magnetic field may lead to an unstable interface, consequently, break down the seal. Aiming at this problem, a new magnetic fluid seal （MFS） was developed. In this new MFS, a soft iron bushing with high permeability was introduced on the shaft and nonferrous shields were installed beside the bushing and the pole pieces. The parameters of the bushing and the shields were optimized in a seal simulation facility. The results show that the bushing with a thickness of 7 mm and shields with a width of 8 mm are best for sealing a shaft 20 mm in diameter. The MFS designed based on the optimum parameters shows good performance and long life span for sealing lubricating oil.

Adaptation of a Biomineralization Strategy for Remineralization of Enamel and Dentin

The bio- inspired strategy of triggered release of Ca^2＋ , Pi, F from prosomal compartments was used to induce rapid formation of FHA for potential dental use ： Calcium and inorganic phosphate salts were separately loaded into temperature-sensitive liposome composed of 90% DPPC and 10% DMPC. When heated from the room temperature to 35- 37 ℃ , the entrapped calcium, inorganic phosphate and fl~rin released from the liposome,A mixture of Ca- Pi and F-loaded liposome formed apatite. The mineral was indicated by a rapid drop in suspension PH from 7.4 approximately 6. This was illustrated by applying a liposome suspension warmed human dentin and enamel surface which resulted in deposition of apatite onto the tissue substrates.     

Preparation of Hemodialyzer Made from Polyethersulfone Membrane by Dual-bath Coagulation Method

The dual-bath coagulation method was used for the preparation of PES membrane in this experiment. The main intent of this stndy was to assess the efforts of gelation conditions on the structures and properties. The dense top layer as well as porous supporting layer can be made by duel-bath coagulation method simultaneous- ly. Different internal quench medium obtained different membrane with different structures. With the increase in time in the first coagulation bath, pure water flux decreased and the clearance rates of urea and creatinine both first increased then decreased and increased slightly in the end. With the temperature of the second coagtdation bath increasing, pure water flux increases and the clearance rates of urea and creatinine first increases then de- creases and increases a little at last. Higher DMSO concentration （wt/wt） in the second coagulation bath results in the increase of pure water flux and the decrease of urea ＆ creatinine clearance rates.
