GIS在环境影响评价中的应用

简要介绍了环境影响评价（EIA）和地理信息系统（GIS）技术的特点，阐述了两者结合的必要性。讨论了GIS技术在环境影响评价领域中的应用现状，重点介绍了GIS技术在项目EIA、区域EIA、累积EIA及战略EIA，环境影响后评价中的应用。在此基础上进一步对GIS在环境影响评价中的应用进行了展望，重点介绍了GIS在公众参与中的应用及基于“5S”的EIA。     

全程自养脱氮工艺的研究

以悬浮填料床作为全程自养脱氮反应器，用不含有机碳的合成氨氮废水进行反应器的启动。系统的氨氮和总氮去除率分别达80％和60％左右。通过批式实验对全程自脱氮做进一步的研究。结果表明，通过控制反应器中DO的浓度，可以控制氨氧化和反硝化的比率；当DO为0.8mg/L时，氨氮几乎完全转化为氮气，氨氧化和反硝化在此时达到了动态平衡；在低DO情况下，氨氮和亚硝氮同时存在，氨氮和总氮的转化率都大幅度的提高，说明氨氮可以亚硝氮为电子受体，在无外加有机碳源的情况下进行反硝化。     

煤矿轴流式局部通风机的降噪试验研究

煤矿局部通风机（简称“局扇”）的噪声是煤矿掘进中的主要噪声源，分析了局扇噪声的产生机理，提出了减少局扇的动叶叶顶与机壳间隙，在局扇入口加阻性消声器和在机壳涂上一层阻尼材料等方法来控制局扇的噪声方法，方法在JBT52－2型局扇的试验研究表明，实施上海降噪措施，局扇的噪声有大幅度降低，可使局扇的噪声达到工矿企业噪声卫生标准要求。

安钢高炉出铁场除尘工程实践

六号高炉炉前出铁场工程是一项工业污染治理项目，该项目结合安钢实际，利用较少的投资，解决了多年困扰炼铁厂的炉前烟尘污染的问题，该技术结合目前国内中小高炉出铁场综合治理的经验，提出了顶吸加侧吸的综合捕集方式，极大地改善了出铁场的烟尘污染状况，同时回收的粉尘又有极高的利用价值，取得了一定的经济效益。     

移动床生物膜反应器充氧能力的试验研究

对移动床生物膜反应器的充氧能力进行了试验研究，结果表明：反应器充氧能力在添加填料比无填料时大；在悬浮载体能够均匀流化的填充率范围内，反应器充氧能力随着填充率的增大而增大；当填充率大于可以均匀流化的最大填充率时，反应器的充氧能力略有下降。     

Cultural and individual differences in self‐rating behavior: an extension and refinement of the cultural relativity hypothesis

This study examined the relationships between culture, individual attributes, and self‐rating behavior among 1,786 university students in Canada, Hong Kong, Taiwan, mainland China, and Japan, and in doing so extended and refined the cultural relativity hypothesis. It explored the difference between vertical and horizontal individualists in self‐rating behavior, and examined the mediating effects of two individual attributes, self‐enhancement propensity and general self‐efficacy in the relationship between individualism and self‐rating behavior. The results confirmed that individualism is the cultural driver for self‐rating leniency, and that the individual‐level assessment of individualism is a stronger predictor of self‐rating leniency than are culture‐level differences. Vertical individualism was found to be positively related to self‐enhancement propensity, which in turn was positively related to self‐rating. Whereas, horizontal individualism was positively related to general self‐efficacy, which in turn had a positive relationship with self‐rating. We discuss the implications of the results for academic research and practical management. Copyright © 2006 John Wiley & Sons, Ltd.

Characterization of cattle fecal Streptomyces strains converting cellulose and hemicelluloses into reducing sugars

To characterize Streptomyces isolated from cattle feces for converting lignocellulose into reducing sugars, five Streptomyces strains were screened. All the strains could convert lignocellulose into reducing sugars. The strain A16 accumulate 3.3-folds more reducing sugars on cottonseed shells treated with ethanol than without the treatment (P?<?0.05). The five strains did not accumulate more reducing sugars on rice straws and wheat brans than those on cottonseed shells. Compared with A10 alone, the microbial combination of F1 + A10 accumulated 19, 61, and 25 % less reducing sugars on cottonseed shell, rice straw, and wheat bran than those by A10 solely, respectively (P?<?0.05). Further studies indicated that the activities of avicelase and xylanase were not correlated with the reducing sugar amount accumulated by the test strains. Strain A7 could produce more cellular lipids with xylose and glucose as the sole carbon sources. This study shows the potential for Streptomyces strains from herbivore feces to convert lignocelluloses into lipids and reducing sugars for fuel production.
