城市轨道交通工程安全验收评价探讨

随着国内城市轨道交通工程的不断建设,其安全问题也变得日益重要。安全评价工作是城市轨道交通建设、运营安全的强力保证,同时也是“三同时”在城市轨道交通中的体现。笔者根据安全评价通则、安全验收评价导则及在南京地铁一号线工程安全验收评价工作的基础上,提出城市轨道交通工程安全验收评价主体思路、评价重点及评价方法。     

浅谈生态影响型建设项目竣工环保验收调查报告编制

阐述了编制生态影响型建设项目竣工验收调查报告的重点和内容。该报告的编制重点应是施工期为减轻施工对周围生态环境影响采取的保护措施调查、竣工后环境恢复措施调查和工程建设前后周围环境质量变化调查与监测;该报告的编制内容包括介绍验收调查任务的由来、验收调查的依据、确定验收调查重点和采用的评价标准,对工程概况和环境概况也需进行简要描述。指出生态环境影响调查水、气、声环境质量调查和环境管理制度调查是调查报告的核心部分,并且环境影响报告结论及有关批复内容和对公众意见调查所起的作用也不容忽视。     

Effect of semantics in the study of tolerance for wolves

As conservation scholars increasingly recognize the critical role of human thought and behavior in determining the persistence of biodiversity across the globe, a growing line of inquiry regarding the validity and comparability of previous applications of core psychological concepts has emerged. Specifically, inconsistent measurement and use of terms, such as attitudes and acceptance, reveal important questions about previous approaches. Given that these concepts differ by definition, yet have been used interchangeably, we explored what drives differences in people's responses when each concept is operationalized in the context of a contested wildlife species, the gray wolf (Canis lupus). To do so, we used data from a 2014 survey of U.S. residents (n = 1287) to test how measures of six concepts (i.e., acceptance, attitudes, benefits, risks, [prior] behavior, and behavioral intentions) often employed in the conservation social sciences were related with a broad set of possible explanatory variables. Despite moderate to strong correlations between all concepts measured (| Pearson's r | = 0.39–0.65, p < 0.001), results revealed considerable variation in their respective relationships with identical explanatory variables. Specifically, although wildlife value orientation (i.e., domination or mutualism) operated fairly consistently across cognitive and behavioral concepts, the relationship between the six concepts and other factors, such as social trust, identification with various interest groups (i.e., hunter, farmer, or rancher, environmentalist, and animal rights advocate), and political ideology (i.e., liberal vs. conservative), varied considerably. Our findings underscore that differences exist in these measures, which could have serious implications for conservationists integrating social science findings in their decision-making processes if they are unaware of the theoretical underpinnings of and distinctions between core psychological concepts.     

化学分析方法校准曲线有关问题的探讨

校准曲线的线性范围为测定下限与测定上限之间的浓度范围,测定上限应尽可能扩大,但要保证校准曲线呈线性,同时,最高点分析后不会对分析系统造成污染物残留。通常应根据分析方法原理、仪器的特点和样品基质情况来确定校准方式。对于线性校准曲线,除了相关系数外,还要根据不同情况,对校准曲线进行检验。校准曲线的合格判定,除考虑相关系数外,还需要用校准曲线重新计算校准点,对于线性校准,所有校准点计算结果拟合值与实际值的相对误差应在±30%以内,对于非线性二阶校准曲线,应进行最大值与最小值检验。     

建设项目竣工环保验收监测中影响数据质量因素分析

煤电项目竣工环保验收监测二氧化硫排放总量问题浅探

将29个煤电项目验收监测核算的二氧化硫排放总量与环保行政主管部门批复的总量控制指标作对比,从运行负荷、脱硫效率、燃煤煤质等方面分析了二者数值存在较大差异的原因。建议在验收监测期间要求企业按环评设计值控制各项参数,并将验收监测总量核算结果作为排污许可或日常监管的参照,进一步强化总量核查与总量控制,推行排污许可证制度。
