有机物

Biochemical Oxygen Demand The BOD is an important measure of water quality.

这是相当数量的措施氧气由细菌和其它微生物需要(在毫克每公升或部份每百万)氧化有机物当前在水样在5 天中。

The oxygen consumed,or biochemical oxygen demand,is proportional to the organic matter converted ,and therefore BOD is a relative measure of the biologically degradable organic matter present in the system .

氧消耗量，或生化需氧量，是成正比的有机质转换，因此，生化需氧量是一个相对的措施，生物可降解的有机物，目前在该系统。

He wastewater of azo dye is characterized with high CODCr,high colority and complication of organic components.

偶氮染料废水具有高CODCr、高色度、有机物成分复杂等特点。

In these paper, ultrasonic degradation of methyl orange by adding lower concentration of CCl4 and effects of organic specials on photocatalytic reduction of hexavalent chromium over different TiO2 photocatalysts have been explored, the results are as follows:(1) Effects of CCl4 were investigated on the ultrasonic degradation of azo dye methyl orange.

本文主要研究了低浓度的CCl4对超声降解甲基橙的影响及有机物对不同TiO2催化剂光催化还原Cr的影响，研究结果如下：(1)研究了低浓度的CCl4对超声降解MO的影响，结果表明少量的CCl4能促进MO的超声降解。

The good news is that, although Urey heats its samples, it does so in water, so the organics cannot burn up.

尤里能加热样本，它可在冬天进行加热，因此有机物不会燃烧。

The structure and properties of composites were characterized by SEM, XRD and DSC.

所采用的相变材料主要包括无机物和有机物二大类。

Methods Decorated houses within 6 months in Changchun were selected with the method of cluster radom sampling.

采用随机整群抽样的方法，在长春市选择装修6个月内的住户，监测甲醛、氨和总挥发性有机物的

Methods Decorated houses within 6 months in Changchun were selected with the method of cluster radom sampling.To examine densities of formaldehyde,ammonia,total volatile organic compounds and complete questionaire.

采用随机整群抽样的方法，在长春市选择装修6个月内的住户，监测甲醛、氨和总挥发性有机物的浓度，同时进行问卷调查。

This paper introduces the studies of Gerhard Ertl, who is awarded the Nobel Prize in Chemistry 2007, in adsorption of hydrogen on metal surfaces, the mechanism of catalytic reaction in Haber- Bosch process for synthesis of ammonia, and the process of catalytic oxidation of CO.

格哈德·埃特尔的重要贡献主要有3方面：(1)解决了氢原子是如何在Pd、Pt和Ni等金属表面组织排列的问题；(2)对哈伯一博施法合成氨反应催化机理的研究；(3)对C催化氧化的研究及非线性动力学理论的建立。1 氢在金属表面吸附的研究萨巴蒂埃因发现精细金属颗粒催化有机物加氢的方法而获1912年度诺贝尔化学奖。

"Regular attendance at chlorinated pools by young children is associated with an exposure dependent increase in lung epithelium permeability and increase in the risk of developing asthma, especially in association with other risk factors," write Alfred Bernard, from the Catholic University of Louvain in Brussels, Belgium, and colleagues.

引起这种反应的物质可能是三氯胺或三氯化氮，加氯消毒的一种高浓度挥发性副产物，很容易被人体吸入，或是当氯与尿、汗水，或其它有机物接触时产生。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
