连续式磁性颗粒去除器在轧钢废水处理中的应用

连续式磁性颗粒去除器，是利用稀土永磁Ｎｄ－Ｆｅ－Ｂ为材质，处理含磁性颗粒废水的装置，其主要结构由动力传递，磁块组合体，磁条移动，设备本体，进出口流道及分离部件等组成，该文阐述了永磁分离机理，并通过磁性悬浮颗粒的理论驱进速度和最小捕获粒径的求解，探讨了提高砒生粒去除器捕 方法，实践证明，该装置用于冶金轧钢废水处理中，能代替传统的轧钢废水三级处理工艺，节约投资成本７０％，占地减少８５％，运行费用亦大幅     

Prenatal application of fluorescent in situ hybridization (FISH) for identification of a mosaic Y-chromosome marker,IDIC(Yp)

An amniocentesis was performed at 13.3 weeks' gestation for advanced maternal age. A mosaic sex chromosome pattern was found: of 50 cells examined, 34 had a 45,X karyotype. In 14 cells with a modal number of 46, a recognizable Y was substituted by a small non-fluorescent marker. C-banding identified the marker as an isodicentric in 12 cells. In two cells, the non-fluorescent marker appeared to be monocentric and looked like a non-fluorescent del (Yq), but could have been an isodicentric Y with inactivation of one of the centromeres. Two cells with a modal number of 47 showed two copies of the monocentric marker. Fluorescent in situ hybridization with an alpha satellite Y-specific centromeric probe confirmed the Y-chromosome origin of the markers and allowed for more accurate prenatal diagnostic information.     

锰砂表面改性去除酚类化合物的研究

本文叙述了锰砂表面改性(以下简称旧锰砂)处理含酚饮用水的实验研究,陈酚率可达99％。本实验对除酚因素(温度、pH值、流速和接触时间等)进行了实验研究。当进水酚浓度≤2.0mg/l时,经旧锰砂的吸附,可使酚浓度≤0.002mg/l。     

企业污染治理设施运行存在的问题和政府管理对策

由浙江省嘉兴市环境保护主管部门的环境处罚案件表明,排污企业污染治理设施运行存在的问题是导致超标排污的主要原因.在通过对该市大量排污企业污染治理设施运行管理情况调查分析的基础上,总结出目前企业内部污染治理设施运行管理中存在的主要问题有:企业对环保工作主观重视程度不够、污染治理设施建设滞后引起超负荷运行、疏于维护管理导致不能发挥正常治污效果、操作管理人员专业文化素质偏低引起操作不当以及处理设施被擅自改变、拆除或者闲置;同时对这些问题的产生原因进行了分析.并从宣传教育、加强企业环境管理、严格执法和推行政策等方面提出了相应的管理对策.     

印尼8.7级和8.5级强震后江苏体应变同震效应分析

2004年12月26日和2005年3月29日在印尼苏门答腊北部分别发生8.7级和8.5级强烈地震后,对江苏地区前兆体应变资料进行分析发现,在这两次地震的震后都记录到了显著的异常,且异常的表现形式各不相同。本文列出这些异常并浅析,以期对进一步深入研究印尼大震对我国未来地震趋势的影响有所帮助。     

Community response to hazard information

The impact of flood hazard information on public acceptance of a selected flood mitigation strategy was assessed by an analysis of the content of newspaper reports of community reaction and letters to the editor. The impact of personal delivery of a flood hazard map on individual perception of risk and attitude to such information was assessed using personal interviews. The results indicated that media coverage of the flood hazard information reduced public criticism of the works. This result must be partially attributable to the dramatic style of media coverage and the fact that the media only emphasized the positive value of the works. The interview demonstrated that personal delivery of the information raised perception of risk, improved comprehension of flood risk, had no impact on acceptability of risk but discouraged some respondents from seeking such information in the future. Factors to explain the last negative change were identified to be the format of the map sheet and low salience of flood hazard. On the basis of all results, methods to improve community response to hazard information are provided.     

对高校扩招有关问题的思考

高等院校扩大招生,满足了广大群众迫切希望接受高等教育的愿望,满足了社会对各种高级专门人才日益增长的需求。伴随着连续的扩招,在高教界普遍出现了基础设施不足,教育质量受到影响的现象,本文针对这一问题进行分析与探讨,并提出了改进的建议。
