电凝聚气浮强化一级处理城市生活污水的试验研究

本文研究电凝聚气浮强化一级处理城市污水的有效性和可行性。采用阳阴级分别为铝板和铁板的电极构造方式进行静态实验、动态实验以及有机物存在状态与去除特性的研究。静态实验结果表明：在原水pH值6．8、电解时间30min、电流密度0．25A／dm^2的条件下，COD、SS及色度去除率分别在70％、70％和88．1％以上，出水COD、SS及色度值分别在120mg／L、40mg／L和40倍以下。动态试验结果表明：COD去除率在70％左右，SS、色度去除率在70％和80％以上，出水COD、SS及色度值分别在120mg／L、50mg／L和50倍以下。     

国产涤纶对出口和内需的贡献

我国被称为世界制造业大国，许多产业排在世界前列，纺织业更是如此。从经贸角度看，一个产品要么在国内消费、要么出口，“拉动内需”和“扩大出口”是经济发展的主题。本文量化地分析了涤纶在国内消费和纺织出口中的作用，并量化分析了国产涤纶和进口涤纶对国内消费和纺织出口的贡献。期望对处于纺织业上游的中石化如何发展自己的聚酯链有所启示。     

Domestic violence, maternal parenting, maternal mental health, and infant externalizing behavior.

This study examined whether maternal functioning mediated the relationship between domestic violence (DV) and infant externalizing behavior. Participants were 203 mother-infant dyads. Support was found for a partially mediated model in which maternal functioning mediated the relationship between current DV and infant externalizing behaviors. Past DV was directly associated with infants' externalizing behavior. Results suggest the need for early intervention and prevention efforts for families living with DV.

试析抽水蓄能电站计算机监控系统国产化的可行性

指出了抽水蓄能电厂与常规水电厂在控制上的主要差别是水泵工况启动和联合抽水控制等问题。水泵工况启动常用变频器(SFC)启动等方式，文中介绍了经国内有关单位改造后的潘家口抽水蓄能电厂计算机监控系统和SFC具有较其他引进系统更为丰富的功能，并分析了引进系统普遍存在的性价比不合理的现象，认为在建和即将建设的大中型抽水蓄能电站采用国产化的计算机监控系统是完全可行的。     

Intergenerational transmission of partner violence: A 20-year prospective study.

An unselected sample of 543 children was followed over 20 years to test the independent effects of parenting, exposure to domestic violence between parents (ETDV), maltreatment, adolescent disruptive behavior disorders, and emerging adult substance abuse disorders, (SUDs) on the risk of violence to and from an adult partner. Conduct disorder (CD) was the strongest risk for perpetrating partner violence for both sexes, followed by ETDV, and power assertive punishment. The effect of child abuse was attributable to these 3 risks. ETDV conferred the greatest risk of receiving partner violence; CD increased the odds of receiving partner violence but did not mediate this effect. Child physical abuse and CD in adolescence were strong independent risks for injury to a partner. SUD mediated the effect of adolescent CD on injury to a partner but not on injury by a partner. Prevention implications are highlighted. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
