文中针对修船浮船坞作业存在的污染水域风险，在综合分析评判两起海损事故船浮船坞作业防污染措施得与失的基础上，分析原因、总结经验、寻找依据，提出了相应的管理对策措施和建议。

The organisms in the mine drainage, which lie in a pink slick on pools of acidic green water, obtain energy by oxidizing iron - that is, generating rust -- and in the process create sulfuric acid and dissole pyrite (iron sulfide or fool's gold) to release more iron and sulfur.

在铁矿排水的地方，这些微生物靠氧化铁离子来获得能量，在这过程中产生更多的硫酸融解黄铁矿，于是产生更多的离子和硫化物，造成水源污染，作者试验的地点中微生物造成了很大污染。

Vegetable and fruitage are subsidiary foodstuffs and one of the important nourishment source in human life.

蔬菜、水果是人们生活中不可缺少的副食品和重要营养来源之一，但化肥及化学农药污染阻碍蔬菜产业的健康发展，其食品安全和潜在的环境污染也令人不安。

Vegetable and fruitage are subsidiary foodstuffs and one of the important nourishment source in human life. But chemical fertilizer and chemical pesticide pollution hindrance the healthy development of vegetable industry, food safety and latent environment pollution always let us uneasy.

蔬菜、水果是人们生活中不可缺少的副食品和重要营养来源之一，但化肥及化学农药污染阻碍蔬菜产业的健康发展，其食品安全和潜在的环境污染也令人不安。

Guards against the facture and the correlation stipulation based on the air pollution defines, the air pollutant may divide into four big projects, respectively be the gaseity pollutant (including sulfur oxide compound bucket carbon monoxide, nitrogen oxide compound, hydrocarbon, chlorine, gasified hydrogen, fluoride, chlorhydrocarbon and so on), the granular pollutant (including suspended particulate matter, golden bureau coal smoke, black smoke, acid fog, falls dust and so on), two pollutant (refers to pollutant to pass through photochemical reaction in air to have pollution again, including photochemistry fog, photochemistry high oxide compound and so on) and odor matter (including chlorine, hydrogen sulfide, curing methyl, sulfur alcohol type, methyl amines) and so on.

依据空气污染防制法及相关规定所定义，空气污染物可分为四大项目，分别为气状污染物（包括硫氧化物勺一氧化碳、氮氧化物、碳氢化合物、氯气、气化氢、氟化物、氯化烃等）、粒状污染物(包括悬浮微粒、金局煤烟、黑烟、酸雾、落尘等)、二次污染物（指污染物在空气中再经光化学反应而产生之污染，包括光化学雾、光化学性高氧化物等）及恶臭物质(包括氯气、硫化氢、硫化甲基、硫醇类、甲基胺类)等。

The most polluted areas is near Tianjin second gasworks and around sewage river as well as sewage irrigation area. So we can conclude the major sources of pollution is atmospheric deposition and sewage irrigation. Second, It is positive correlation between the heavy-metal contamination and layered silicate minerals, while it is negative correlation between heavy-metals and quartz , feldspar as well as other minerals.

二、重金属污染元素含量与层状硅酸盐矿物含量呈正相关，而与石英长石等矿物含量呈负相关，充分说明污染元素主要赋存在层状硅酸盐矿物中，这与矿物自身的结构有着密切的关系，层状硅酸盐矿物具有很大的层间域，有利于对其他物质的吸附作用。

Based on the data of aerosol chemical compositions obtained at WMO GAW (World Meteorological Organization Global Atmospheric Watch) station in eastern China－Lin'An regional background air pollution monitoring station, two methods (referred as Malm method and Stelson method) that were described by Malm (Malm et al.,1994) and Stelson (Stelson and Seinfeld, 1981) were used to study the mass closure of sampled aerosols.

本文通过在WMO GAW 区域大气本底污染监测站－临安大气本底污染监测站采集的气溶胶样品的化学成分的分析结果，分别用Malm（1994）和Stelson（1981）提出的方法（分别记为Malm方法和Stelson方法）重建气溶胶质量浓度，并与称重获得的质量浓度进行对比，发现虽然Stelson和Malm方法所考虑的物质组成及所使用的化学成分个数并不相同，其计算结果略有差异，但总的来说两种方法都能较好的反映绝大部分的气溶胶质量，在实际应用中可以根据所分析的化学成分数据情况和研究的目的采用不同的质量重建方法。

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。
