| 1 | 喷嘴雾化特性实验研究显示文摘液体雾化是当前两相流研究中非常重要的课题,在农业、能源以及环境工程中具有广泛的应用价值,进行深入系统的研究具有重要意义。本文以空气、水为工质,使用马尔文粒度仪对单相和两相雾化器喷嘴的雾化特性进行了比较实验研究。测量了不同压力配比条件下液体雾化粒子的粒径分布,详细讨论了压力对于喷嘴雾化效果的影响。同时得出了两相流量与压力之间的变化规律。 | 陈斌 郭烈锦 张西民 高晖 Panidis Th. Papailiou D.D. | 2001 | 工程热物理学报2001,22,2: | 102 |
| 2 | 中国大陆社区心理学发展的现状、困难与机遇显示文摘对CNKI'学术文献总库'中有关社区心理学的研究成果进行检索,使用Endnote的文献管理与分析功能、CNKI的学科类别分组功能以及内容分析法对检索结果进行分析,得出中国大陆社区心理学研究的现状:(1)成果总量不多,2000年以后出现增长趋势;(2)尚未出现特定的'研究中心',包括具有明显领先优势的研究者或研究机构、集中发表该领域研究成果的专业刊物或出版单位等;(3)出自心理学的研究成果最多(约占成果总数的1/3),其他学科类别依次为医学、社会学及统计学、医疗卫生政策与法律、教育与管理等;(4)研究对象集中于'老年人'和'青少年'两个群体,关注心理健康和心理干预问题;(5)主要采用测量和调查等实证研究方法,研究对社区实践的卷入不深。中国大陆社区心理学的发展面临三重阻力:(1)自上而下的行政化社区管理体制造成公民(包括心理学家在内)社区意识的普遍淡漠,致使社区心理难以进入心理学研究的视域;(2)心理学家普遍重视理论研究,对参与社会实践较少兴趣和经验;(3)实证主义研究范式的心理禁锢。社区心理学在中国同时也面临发展机遇:首先,社会改革与发展过程中涌现出大量的社会心理问题,政府和社会对解决这些问题的迫切需求为社区心理学的发展创造了契机;其次,大型组织和企业积极参与行动研究对社区心理学的发展起到助推作用;第三,心理学学科自身生存与发展的需要为社区心理学的发展提供了内在动力。 | 杨莉萍 D.D.珀金斯 | 2012 | 华东师范大学学报(教育科学版)2012,30,2: | 32 |
| 3 | Electrical and optical properties of lithium borate glasses doped with Nd_2O_3显示文摘Glass series with general formula 25Li2O-(75-x)B2O3-xNd2O3 was prepared by conventional melt quench technique. Electrical and optical characterizations of these glasses were carried out. It was observed that conductivity of glasses decreased and activation energy increased with the addition of Nd2O3. The density and refractive index of the glasses increased while optical band gap and radiation length decreased due to structural changes. | R.S. Gedam D.D.

| 9 | 应用超临界温度氢吸附数据表征活性炭结构显示文摘为准确研究氢在活性炭上的吸附平衡,本文对比分析了由氮和氢在活性炭上吸附数据确定的活性炭的孔径分布(PSD)。首先,应用容积法,在0~12.5MPa压力范围、3个温度(113.15K、193.15K、273.15K)下测定氢在K05活性炭上的吸附平衡数据,并由引入系统内氢的质量衡算确定吸附池内氢的总量。其次,以77K氮吸附数据确定的PSD为初值、以吸附池内氢的总量为基准,通过优化非局域密度泛函理论(NDFT)计算值确定活性炭的PSD,进而比较表征介质、温度及平衡压力对PSD的影响。研究表明,应用氢吸附数据表征孔宽小于0.8nm的超细微孔的微分容积较大;平衡压力较高时,由不同温度氢吸附数据确定的超细微孔的PSD相近;孔宽大于1.2nm时,不同温度氢吸附数据确定的PSD间有明显偏差。须应用超临界温度高压氢或氢在亚临界温度区域的吸附数据,同时结合77K氮吸附等温线来表征吸附剂在超细微孔和微孔范围的PSD。 | 郑青榕 Do D.D. 陈武 蔡振雄 | 2010 | 离子交换与吸附2010,26,6: | 2 |

| 12 | 南非水权发展历程显示文摘简要地回顾了南非水权近300余年来的发展历史。早在1652年,荷兰公司的管理者宣布:水是公共商品,河流属国家所有,在该国强制推行罗马-荷兰法律。而英国则相反,水被私有化,并将其与土地占有制结合起来,从而确立了河岸权制至高无上的原则(supremacyoftheriparianprinciple);南非种族隔离政府试图再一次偏重于罗马-荷兰法律。但是,民主制度下的现代法已经将中央政府指定为水资源的托管人,其主要目的是为了公众利益促进水资源的有效、可持续以及有益的利用,并向全体人民提供公平用水。但是,它的职责比立法者赋予的多得多。 | D.D.特瓦里 孔祥林(译) 刘忆瑛(校) | 2006 | 水利水电快报2006,27,22: | 2 |

| 14 | 甲氨蝶呤治疗前后银屑病皮损中ICAM-3、Ki-67、PCNA及CD31表达的变化显示文摘Although the effectiveness of methotrexate (MTX) in the treatment of psoriasis is very well established, the mechanism of action is poorly understood. It was suggested that the therapeutic effect of MTX in psoriasis might be mediated by inhibition of adhesion molecule expression. The aim of our study was to investigate the different effects of MTX treatment on cell proliferation, inflammatory infiltrate, adhesion molecules, and angiogenesis in psoriasis, and to clarify the mechanism by which MTX exerts its therapeutic effects. Clinical response, the morpho- phenot- ypic changes, epidermal thickness, and mitosis count were analyzed and the expression of CD31 and ICAM- 3, proliferative markers such as Ki- 67, PCNA, were evaluated by immunohistochemical techniques in lesional psoriatic epidermis, before and after the treatment with MTX in ten patients. In posttreatment biopsies a decrease in the degree of epidermal hyperplasia and a significant reduction in the severity of the inflammatory infiltrate (P< 0.05) were observed. In addition,CD31 and ICAM- 3 expression was significantly decreased ondermal cellular infiltrate, (respectively; P< 0.05,P< 0.01). Ki67 and PCNA expression were suppressed concurrently in about 90% of cases (P< 0.01). We suggest that MTX may have an inhibitory effect on an initial integral component of the pathways that lead to psoriasis. Immunopharmacologic intervention in adhesion event has the potential to improve psoriasis. Inhibition of revascularization may be another mechanism of actionof MTX. | Yazici A.C. Tursen U.
