查询词典 contaminants

In addition to the movement of contaminants in water, there is a myriad of complex chemical and microbiological processes

由于水中污染物的迁移，会发生大量的复杂的化学和微生物转化过程

These contaminants will acidify the water once they begin to decompose and therefore you will end up drinking acidic water which pushes your already high level of acidity even higher.

这些污染物将酸化水一旦开始腐烂，因此，您最终将饮用酸性水，你已经把高水平的酸度甚至更高。

There's even an afterword from real astronaut Buzz Aldrin in which he stresses the impossibility of the existence of flies or other contaminants aboard the historic space shuttle.

甚至还有一个后记从真正的宇航员奥尔德林，他强调存在不可能的苍蝇或航天飞机其他污染物登上历史。

Chunk-light tuna is preferable to albacore or sushi, because it usually contains fewer contaminants, such as mercury.

吞拿鱼比青花海产鱼更好，更加适合做生鱼片，因为它所含的污染物比如汞比较少。

So it is necessary and imperious to develop a new method to sample organic contaminants continuously in the exposed medium in a certain range of time and to concentrate organic contaminants to a detected degree.

因此，寻找新的可在一定时间范围内连续采集暴露介质中的有机污染物，并将其浓度浓缩到一定程度的采样方法，显得非常必要和迫切。

Semiconductor industry has been a central figure to the economic growth in Taiwan, especially for the fabrication sector of integrated circuit that has evolved into world-leading status. The fabrication technology advances so far that the feature size (or critical line-width) of IC devices has now broken the 0.1 ?慆 barrier and into the nano-scale age. This progress discloses that the traditional definition of a "cleanroom" environment may become increasingly inadequate because prevention of particulate contamination may no longer be a critical issue. As the condensable organic airborne molecular contaminants depositing on wafer surfaces, it results in deterioration on device performance and reduces semiconductor device yield.

半导体产业已成为我国最重要的经济发展产业，其中积体电路制造技术的快速发展，使我国早已跃升成为世界晶圆代工重镇之一，然而当制程的关键线宽尺寸突破0.1微米而正式进入奈米等级之际，传统针对微粒污染控制所设计之洁净室将无法符合气态分子污染物之洁净需求，其中凝结性有机分子污染物质(organic airborne molecular contaminants)一旦沈积吸附於晶圆表面，将导致元件缺陷与制程良率下降。

Active hydrogen atom and oxygen ion form Hydroperoxy radicals which surround the positively charged biological contaminants, and then react with three hydrogen elements of its protein structure, destroying and detoxicating the biological contaminants nature.

活性氢和氧离子(O2-)形成的氢过氧自由基，会包围着带正电荷的生物污染物，每一枚黏附在污染物表层的氢过氧自由基，会与其蛋白质结构中三个氢元素产生反应，完全破坏其结构，变成无毒状态。

Experimental results indicated that the contaminants generally existed in mussel, such as α-HCH,β-HCH,γ-HCH,δ-HCH, o·p-DDT, p·p-DDT, p·p-DDD, were degraded completely under the above conditions, whereas DDE, aldrin and dieldrin were partly degraded. No detectable degradation of PCB 1242 and PCB 1248 were observed. Thus the conventional preparation of the contaminants using the columns packed with Florisil or SiO〓 could be left out.

测定贻贝中的PCBs时，以KOH甲醇溶液处理试样，在微波能作用下，试样的微波皂化与有机氯农药的微波碱解同时进行；测定土壤和沉积物中的PCBs时，以KOH甲醇溶液处理试样，在微波能作用下，PCBs的微波萃取与有机氯农药的微波碱解同时进行，1M KOH甲醇溶液对PCBs的微波萃取能力与纯甲醇溶剂相当。

The application of fish, frogs, and minks as sentinel animals for human health risk evaluation of environmental contaminants was reviewed in this paper, and their merits and disadvantages and applicable ranges were discussed, respectively. Finally, we suggested that ecotoxicological survey on sentinel animals in China should be developed to promote human health risk evaluation of environmental contaminants.

论文对作为前哨动物的某些鱼类、两栖动物和哺乳动物在环境污染物人体健康风险评价中的应用进行了简要概述，讨论了它们作为前哨动物各自的优缺点和适用范围，最后建议在国内大力开展前哨动物生态毒理学调查，以促进人体健康风险评价工作。

On the PRBs. Experiments results indicated that under the same condition, the treatment effect of contaminants directly correlated with retention time of contaminants in rectors; ZVI take an important role on decomposing the complex non-biodegradable or difficult biodegradable org...

实验结果表明：在相同条件下，污染物的处理效果与滞留时间直接相关；零价铁对复杂的不可生物降解或难生物降解的有机物向简单有机物的转化起了重要作用，经过反应器后使ρ(BOD5)/ρ值从初始0.32增至0.5~0.79，增强了有机物的可生物降解性；不同的辅助反应介质对污染物的去除具有一定的选择性。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
