污染

With this precaution, there was no possibility of contamination and there is no record that any occurred.

在这种预防措施下，不会有发生污染的可能，也没有污染出现的记录。

The strategy and controller are coming from combined analysis of combustion mechanism, generation mechanism of pollutants, influential elements, present application status of PID control method in combustion, as well as sum-up of controlling experience and contradistinctive researches of control strategies. It is shown that this method, when applied to furnace temperature controlling and activated-sludge process, is able to ensure controlling objects tracking in the presence of varying operation conditions, as verified via computer simulation. The thesis consists of chapters as following: Chapter 1 generalizes the research objective and brings forward the inferior theme; generation mechanisms of pollutants

The contamination of atmosphere still give priority to type of coom in our country.the main contaminations is SO2 and soot.

摘要我国的大气环境污染仍然以煤烟型为主，主要污染是SO_2和烟尘，酸雨问题依然严重。

The question of how to coordinately handle the relationship between environment protection and social development has became an important topic and is being discussed worldwide.

作为污染的一种，海洋环境污染尤其是船舶油污对人类生存环境的严重危害性同样引起各国的广泛关注，防止船舶油污亦成为国际间的热门话题。

The ecosystems were classified into 13 types including valley rain forest, mountainous rain forest, tropical monsoon forest, mountainous coppice forest, mountainous ever green forest, tropical coniferous forest, shrubs, plantation, timber forest, windbreak forest, mangrove, savanna, and crop land, and then, the regulation services and their economic values of Hainan Island ecosystem were assessed and evaluated by terms of water-holding, soil-conservancy, nutrient cycle, C fixation, and windbreak function.

研究表明，2004年海南岛基于生态系统服务功能的绿色GDP为1042.80—1072.84亿元。其中传统GDP为769.36亿元、环境污染经济损失为10.54亿元、生态GDP为283.98—314.02亿元。经分析可知道：海南岛由于工业并不发达，其环境污染损失并不严重，只占传统GDP的1.4％；然而海南岛生态系统服务功能所提供的价值却是非常大，其中生态GDP是传统GDP的37％—41％。

Coal as fuel is an important sources for heavy metals in Chengdu city. At present, there are lack of studies on corelation between the content of heavy metals in Chengdu coal and urban environmental pollution.

燃煤是成都市重金属污染的一个重要来源，目前对成都燃煤中重金属元素含量与城市环境污染的相关性研究相对较少。

This paper is focus on the measurement of laminar flame propagation velocity of premixed CH4 with air under two kinds of conditions through the counterflow experimental system.one is with steam catalytic reforming reactions;the other is not.

燃烧系统的各种排放物是空气的主要污染源，城市中的机动车的污染已形成越来越大的威胁。自上世纪70年代末，我国机动车的污染排放量以每年12.7%的速度递增。

Cresol is a common pollutant from industries, it impacts on the aquatic ecosystem and environmental balance extremely, and biodegradation is a very economic technique, which is the best choice of the cresol contaminated soil remediation.

摘要 甲酚为工业上常见的污染物质之一，对水域生态与环境平衡冲击甚大，以生物降解方式因具较高之经济效益，故可做为土壤甲酚污染整治的最佳选择之一。

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.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
