1我国城市非点源污染特征及其模型应用探讨显示文摘总结了城市非点源污染的定义,探讨了城市非点源污染的种类、来源、危害、影响因素等特征。为估算城市非点源污染负荷,国外学者研发了许多模型,如SWMM、STORM、MOUSE等。但因我国城市非点源污染具有浓度高,来源多(包括城市道路、屋面、广场、天然降雨、路边垃圾、重点生活源、管网淤积等),且主要来自于城市道路等特点,国内学者在应用国外模型计算城市非点源污染负荷时可能会遇到一些问题和困难。基于我国城市非点源污染特征及当前SWMM模型在我国的应用,提出了我国在应用模型模拟计算城市非点源污染时需注意的模型参数取值及验证、模拟污染物类型选取、基础资料获取等相关问题,并展望了我国未来城市非点源污染的研究方向。秦攀 雷坤 KHU Soon-Thiam 乔飞 2016环境工程技术学报2016,6,4:10
2子汇水区划分精度对SWMM模拟城市非点源的影响显示文摘SWMM作为动态模拟的城市非点源污染模型,被广泛应用于城市非点源负荷估算研究,并在很多小尺度研究中取得了很好的效果。随着中国城市发展不断加快,城市非点源污染研究的空间尺度也随之变大,如何科学合理选择建模时子汇水区划分精度成为研究中一个重要问题。文章主要分析SWMM应用于城市区域非点源污染模拟时,不同子汇水区划分精度对水质模拟结果的影响,并在此基础上,以降低SWMM建模工作量并保证模拟结果的准确度为原则,对如何选择子汇水区的精度进行了深入的探讨。结果表明事件降雨为降雨输入时,子汇水区划分精度对水质模拟结果影响较大,宜采用高精度或高中精度模型;单月份和雨季连续降雨为降雨输入时,子汇水区划分精度对水质模拟结果影响较小,可以使用低精度模型。秦攀 雷坤 乔飞 Soon-Thiam KHU 2016环境科学与技术2016,39,6:10
3Activated carbon derived from rice husk by NaOH activation and its application in supercapacitor显示文摘Four activated carbon(AC) samples prepared from rice husk under different activation temperatures have been characterized by N2adsorption–desorption isotherms, thermogravimetric analysis(TGA–DTA), Fourier transform infrared spectroscopy(FTIR) and scanning electron microscopy(SEM). The specific surface area of AC sample reached 2681 m2 g 1under activation temperature of 800 1C. The AC samples were then tested as electrode material; the specific capacitance of the as-prepared activated carbon electrode was found to be 172.3 F g 1using cyclic voltammetry at a scan rate of 5 mV s 1and 198.4 F g 1at current density 1000 mA g 1in the charge/discharge mode.& 2014 Chinese Materials Research Society.

4Application of the Dermatology Life Quality Index in Clinical Trials of Biologics for Psoriasis显示文摘The significance of patient-reported outcomes(PROs) is increasingly being acknowledged and quality of life(QOL) has become an integral element of the assessment of overall burden of disease.Psoriasis has been known for its major impact on patients' QOL and various generic,dermatology-specific and psoriasis-specific self- administered psychometric instruments have been used over the years to assess the QOL of psoriasis patients.However,the Dermatology Life Quality Index(DLQI) is the most widely used QOL measure among these measures in psoriasis-related clinical trials. A number of topical and systemic treatments have been used in the management of psoriasis and lately biologics have emerged as a new and promising treatment modality for difficuIt-to-treat psoriasis.The evidence on the efficacy of these agents has been growing dramatically with QOL being used as one of the primary outcome measures in many clinical trials.The aim of this paper is to give an overview of the use of the DLQI as an outcome measure for assessing the QOL impact of biologies on psoriasis patients.Furthermore,the efficacy of five commonly used biologics has been compared in terms of their ability to improve the QOL assessed by the DLQI.This review has revealed that there is a variation in the efficacy of various biologies in terms of QOL improvement with the mean reduction in the DLQI scores being highest for ustekinumab 90 mg(mean DLQI score reduction=9.5),followed by infliximab(8.5),etanercept 50 mg,twice a week(7.7),adalimumab(6.3),and alefacept(4.0).Mohammad Khu rshid Azam Basra Sadath Hussain 2012Chinese Journal of Integrative Medicine2012,18,3:4
5永定河三家店以上流域径流减少归因分析显示文摘20世纪70年代以来,永定河流域径流特征发生了巨大变化,下游常年处于断流状态。根据1956—1991年及2006—2018年永定河三家店以上流域各站的气象与水文数据,利用M-K检验和小波分析方法分析了永定河流域的气象要素及径流变化趋势,利用双累积曲线和基于Budyko假设的弹性系数法进行了径流减少归因分析。结果表明:①1956—2018年间永定河流域的降雨无明显增加或减少趋势,气温有显著上升趋势,蒸发能力略有下降,径流减少非常明显,达到99.9%置信水平。②永定河流域大部分站点的降雨和径流变化存在大概11或23 a的波动周期。③永定河10个水文站的降雨-径流双累积曲线均发生了2~4次较为明显的偏移,在20世纪的60年代中期、70年代初期、80年中期和90年代初期都发生了偏向径流的偏移,这表明在降雨量水平未发生明显变化的情况下,径流减少了。④永定河流域是强人类活动区域,弹性系数绝对值依次为:降水>下垫面参数>蒸发能力,人类活动对径流减少的平均贡献率约为95%。彭弢 贾仰文 牛存稳 刘欢 KHU Soon-Thiam 2022水利水运工程学报2022,,1:3
6中水回用对社区景观水体叶绿素a变化的影响显示文摘由于中水的营养盐含量较高,以中水为补水水源的社区景观水体存在较大的水华暴发风险.基于中水回用于景观水体的换水控制实验,建立了中水景观水体的富营养化模型,模拟了连续换水时和终止换水后叶绿素a的变化过程,分析了中水水质和换水周期对水体藻类生长的影响.结果表明,提高中水水质可以降低水体的叶绿素a峰值;在连续换水期,随着换水周期的缩短,水体的叶绿素a峰值降低,并且从开始换水至达到峰值的时间增长;在连续换水期后终止换水,叶绿素a会重新达到峰值,并且原来的换水周期越短,水体的叶绿素a峰值反而越高,达到峰值所需时间越长.模型应用可为中水回用于社区景观水体的水量水质设计与维护提供依据.李畅 秦华鹏 Soon-Thiam Khu 王波 2010中国环境科学2010,30,10:2
