It was found that the quenching diameter of porous media is a multi-parametric complicated function, related to the mixture flow speed, the premixed gaseous laminar flame velocity, the pipe flow Reynolds numbers, the coefficient of temperature conductivity, the equivalence ratio and the soUd temperature.

为缓解能源结构不合理造成的环境污染问题，我国加快了天然气的使用力度，发展高效、低污染排放的天然气燃烧技术具有非常重要的现实意义。

In this paper, spectral reflectance of stressed rice by cadmium and copper in soil was discussed. A high resolution spectroradiometer.

中文摘要：本文讨论了水稻受重金属镉和铜污染伤害后的光谱反射特性的变化，为遥感监测污染提供基本依据。

Compared with E. nuttallii, PCs in roots of P. stratiotes L. was sensitive to Cd contamination and may be a sensitive indicator to reflect Cd toxicity in the aquatic ecosystem.

比较而言，水浮莲体内PCs对Cd污染更为敏感，可通过检测其根系PCs的含量来评价和预测实际水环境中Cd的污染。

This paper investigates that the different composition of the headspace gas and polluted sediment slurries can affect the ratios of degradation on benzoic acid, toluic acid and phthalic acid isomers. We found that a sediment slurry which has been polluted can develop a stronger microbial degradation.

此篇文章主要是探讨不同上层气体之组成和被污染过之底泥可影响苯甲酸、甲基苯甲酸异构物及苯二酸异构物被分解的速率，我们发现被污染过之底泥可发展出较强之微生物降解力。

Of particular interest are:Toxic or biologically disruptive impacts of anthropogenic chemicals and by-products;Natural toxins and their impacts;Biotransformation and metabolism of toxigenic compounds, food chains for toxin accumulation or biodegradation;Assays of toxicity, endocrine disruption, mutagenicity, carcinogenicity, ecosystem impact and health hazard;Environmental and public health risk assessment, environmental guidelines, environmental policy for toxicants.

包括人为因素造成的污染；自然因素造成的污染，以及它们的破坏作用；生毒物质的生物转化和新陈代谢，导致毒素积累和生物降解的食物链；毒性、内分泌损害、诱变、致癌、生态系统影响和健康危机；为毒性环境和公众危机评估、环境指导、环境政策。

The government wants to reduce pollution to 120 units, so it gives each firm 40 tradable pollution permits.

政府想减少污染到120个单位，所以给每个企业40个单位的污染许可证。

The success was mainly due to the dilution of sea water to certain extent ( 25-50%) so that the Tradescantia inflorescences could remain alive during the time pe-riod required in the experiment.

我们发现紫露草能于海水中在实验要求的时间内成活，并通过实验证实了微核产生的原因不是海水本身，而是海水中的污染物质，污染物质含量越高，产生微核的频率也越高。

Currently microbioremediation is a long process for the most of oil contamination is undegrading by general bacteria in the soil and the limitation of soil qualification.

微生物修复是一种经济而且无二次污染的污染治理技术，具有其他修复技术难以比拟的优势。

Therefore, the development trends are: to establish the dynamic NSP pollutant transport and transformation model which can be applied easily to ordinary natural watershed; to study the estimation methods of NSP load and model parameterized in terms of geomorphic parameters (Horton's numbers) for ungauged watershed.

因此，发展趋势为：第一，建立以污染物迁移转化机理为基础的、适合于野外流域和便于推广应用的非点源污染负荷模型；第二，研究无资料地区的非点源污染负荷估算方法与模型参数估计途径。

The relation between unhairing effect and residual sodium sulfide in limed water was studied to lead to a complete solution of sulfide, lime and organic substance pollution in unhairing and liming process.

实验首先研究了脱毛废液中残余硫化钠含量与脱毛效果的关系，从理论上和实际应用中都解决了脱毛废液中硫化物、石灰和有机物的污染，将污染消除在生产过程中。

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。
