微电解处理低电导印染废水及热效应研究

针对低电导印染废水难处理的特点，采用微电解法对该废水进行了实验研究。在电压一定的条件下，通过改变NaCl电解质的投放量，得到处理该废水的最佳工况。同时，从实验现象中得出温度的变化是影响该废水处理效果的因素之一的结论。从热力学理论研究的角度出发，进一步论证了该结论。     

Assessing the Vulnerability of Coastal Communities to Extreme Storms: The Case of Revere,MA., USA

Climate change may affect the frequency, intensity, and geographic distribution of severe coastal storms. Concurrent sea-level rise would raise the baseline of flooding during such events. Meanwhile, social vulnerability factors such as poverty and disability hinder the ability to cope with storms and storm damage. While physical changes are likely to remain scientifically uncertain into the foreseeable future, the ability to mitigate potential impacts from coastal flooding may be fostered by better understanding the interplay of social and physical factors that produce human vulnerability. This study does so by integrating the classic causal model of hazards with social, environmental, and spatial dynamics that lead to the differential ability of people to cope with hazards. It uses Census data, factor analysis, data envelopment analysis, and floodplain maps to understand the compound social and physical vulnerability of coastal residents in the city of Revere, MA, USA. This revised version was published online in August 2006 with corrections to the Cover Date.     

酞酸酯类有机毒物在土壤中降解规律的研究

研究了酞酸酯ＤＥＨＰ和ＤＢＦ二种增塑剂在土壤中降解规律，结果表明：土壤中ＤＥＨＰ和ＤＢＰ的降解速率可以用一级动力学方程描述，不同类型土壤对酞酸酯的降解能力是有所差别的，ＤＢＰ在土壤中比ＤＥＨＰ容易降解，土壤灭菌后，降解能力明显降低，按种接解微生物后，土壤中ＤＥＨＰ降解速率明显加快，土壤含水量和温度影响ＤＥＨＰ和ＤＢＰ的降解速率；本试验从土壤中分离出降解ＤＥＨＰ的细菌９株和真菌１１株。     

原子吸收测锰时硅的干扰及消除

用原子吸收空气－－乙炔炎焰法测定锰时，硅会对其产生严重干扰，若等量加入２５ｍｇ／Ｌ钡或１００ｍｇ／Ｌ镧则足以消除这一干扰作用，尤其是加入后者，可获得较真实的测值。     

汉江上游斜坡破坏的变异

滇黔桂地区铊富集的矿化剂和沉淀富集剂及成矿模式

Tl虽然是一种分散元素 ,但在一定条件下也是可以富集的 ,甚至形成独立矿体。笔者在分析滇黔桂地区富铊矿床的地球化学特征后 ,认为Tl在低温阶段富集 ,并提出Tl的富集与沉积盆地局部高地球化学背景有关 ;促使Tl富集成矿的主要条件是矿化剂和沉淀富集剂 ,卤素和有机质是主要的矿化剂 ,富硫流体和热液改造的有机质是主要的沉淀富集剂。在此基础上进一步探讨了铊的二期三阶段成矿模式     

LS系列硫磺回收催化剂工业装置使用总结

对比总结了LS系列催化剂的使用情况，结果表明，在一级转化器均装填LS-931Al2O3基催化剂的前提下，二级转化器上部装填LS－971脱氧保护型催化剂，下部装填LS－811Al2O3催化剂后，与单纯使用LS－931催化剂相比，单器转化率由64．1％提高到70．1％，有机硫水解率由96％提高到接近100％，两项合计使装置总硫转化率由95．1％提高到96．2％，若与两个转化器全部使用LS－811催化剂相比，则装置总硫转化率可由94．49％提高到96．2％使用效果更加显著。

A synergetic model for implementing an integrated management system: an empirical study in China

The implementation and certification of quality, environmental and occupational health and safety management systems have become a priority for many organizations. They are viewed as symbol for success and prerequisite for survival. However, it has been proved to be difficult to operate multiple parallel management systems covering quality, environment, and occupational health and safety and to ensure their alignment with the organization's strategy. To investigate the current status of integrated management system (IMS), a structured questionnaire survey was administrated. It is concluded that the major problems for enterprises to operate multiple parallel management systems include: it causes complexity of internal management, it lowers management efficiency, it incurs cultural incompatibility, it causes employee hostility, and increases management costs. The survey also examined the internal and external factors that affect the implementation of IMS. The internal factors include: (1) human resources, (2) organizational structure, (3) company culture, and (4) understanding and perception. The external factors consist of: (1) technical guidance, (2) certification bodies, (3) stakeholders and customers, and (4) the institutional environment. The article proposes a multi-level synergy model (strategic synergy, organizational structural-resource-cultural synergy, and documentation synergy) for an effective implementation of IMS.
