The development condition about briquettes industry and technology is analyzed and studied in the thesis, and the conclusion is drawn by combing present energy and air pollution condition in our country.

对型煤工业与技术的发展状况进行了深入的分析和研究，结合我国的能源及大气污染现状得出结论，即型煤具有良好的环境和经济效益，是现阶段解决我国北方城市煤烟型大气污染的唯一途径

After all, it was only thirty years ago in the United States that a major river spontaneously combusted and that air pollution would occasionally get so bad that motorists would turn their headlights on during the day to be seen.

毕竟，在短短30年之内，美国的主要河流就有可能被严重污染。空气污染变的如此严重以至汽车司机在白天都要打开车前灯才能看清路况。

This paper discusses in detail that coulometry quickly measures chemical oxygen demand of low polluted domestic sewage of the school and high polluted industrial sewage.

本文详细论述了库仑法快速测定低污染的校区生活污水和高污染的工业污水中的化学耗氧量。

ECOD activity was induced by BaP, TBT or their mixture at high concentrations after 50 days exposure, and it is advisable to use ECOD activity as a biomarker to assess severe PAHs or TBT pollution. UDPGT was analyzed as phase II enzyme.

ECOD活性在BaP、TBT或者二者的联合作用下主要表现出被诱导效应，也能反映出高浓度的BaP和TBT联合污染情况，可以作为高污染环境中的生物标志物参考指标。

EROD and ECOD are both phase I enzymes. There were complicated relations of time-effect and dose-effect between EROD activity and exposure of BaP, TBT or their mixture. Antagonistic interactions occurred after 25 days exposure to the mixure of BaP and TBT. It is fuzzy to merely use EROD activity as biomarker to assess PAHs or TBT pollution.

相解毒酶EROD活性与BaP、TBT及其混合物污染之间存在较为复杂的时间-效应与剂量-效应关系，而且在暴露25 d后，联合作用表现为拮抗作用，仅仅以EROD酶活性指标衡量环境中BaP、TBT或者二者的联合污染水平会出现失真现象。

Objective To explore the clinical value in examining morphology of red cell in urine for those enfants with kidney injury by eating melamine contaminated formula.Methods Examined morphology of red cell in 296 urine samples from enfants eating melamine contaminated formula.Gave statistic analysis to 7 key indices.

目的 探讨尿红细胞位相检测对于服食三聚氰胺污染奶粉造成的儿童肾脏损伤诊断的临床意义方法对296例服食三聚氰胺污染奶粉儿童尿液进行红细胞位相检测，分别得出7项指标，结果进行统计分析。

The effect on diversity of eubacteria in submerged paddy soil with phenanthrene was also studied using the denaturing gradient gel electrophoresis technique.

在传统微生物污染生态研究基础上，运用PCR-DGGE方法，对菲污染条件下稻田土壤真细菌种群的基因多样性进行了初步研究。

Wetlands and Non-Point Source Factsheet - Managing Wetlands to Control Non-Point Source Pollution - This is one in a series of factsheets designed to help the public increase their understanding and management of non-point source pollution in their community.

湿地和非点源资料单张-湿地管理控制非点源污染-这是一个旨在帮助市民增加他们的理解和管理非在他们的社区点源污染概况介绍系列之一。

Protecting fertilizer and preventing pollution Making the leakage losses of soil nutrients reduce more than 85%, improving the utilization efficiency of fertilizers; reducing the pesticide content in the runoff, preventing the pollution of groundwater and river and lake water.

保肥防污染，使土壤养分的渗漏损失减少95%以上，提高肥料的利用率；降低泾水中的农药含量，防止地下水和河湖水体污染。

Because sheet of the known that the leakage will bring the environment problems in early days the power station constructed, generally not adopt technical measure of defending seeping, the groundwater environment changed obvious influence by the ash water leakage, the paper take the ash field of JiNing Power Station as an example, through the data contrast of the plain ash field water level and water quality in the time and on the apace, expresses that the groundwater of ash field district has already suffered pollution, generally, the scope of the pollution is in 1 kilometer.

由于早期电厂建设时对灰场渗漏引起的环境问题缺乏认识，一般不采以专门的防渗措施，灰水渗漏对地下水环境产生了明显的影响。论文以济宁某电厂灰场为例，通过对平原灰场水位、水质在时间和空间上的数据对比表明灰场区地下水已遭受污染，其污染影响范围一般小于1km。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
