In this paper, the relation of sludge and the overlying water was analyzed.

1、摘要部分与本文正文没有很好的结合起来，很大部分阐述底泥与上覆水之间的关系，对疏浚一句带过，这样似乎颠倒了本文的论述重点。

Cu、Ni、Pb and Cd showed more affinity to the oxidizable metal fraction. Bio-availability of all the measured metals, except Cd,decreased with the increase in composting time. Therefore, we conclude that composting could stabilize the heavy metals present in the sludge and decrease the risk of soil pollution.

污泥堆肥中Cu、Ni、Cd、Cr主要以残渣态形式存在，Cu、Ni、Pb、Cd四种重金属元素的可氧化态含量也相对较高，除Cd外，经过堆肥化处理后所有重金属的有效态含量均呈下降趋势，因此，堆肥可以促进污泥中的重金属稳定化，降低土壤的污染风险。

The results showed that the heavy metals in various mediums were mainly Cu and Ni, and those concentrations were, in the descending order, in ditch, tailings, slagheap and cultivated soil. In the tailings and the sludge of the ditch, the concentrations of Ni were obviously higher than those of Cu. Whereas, in the soil and the weathering and atmospheric deposition of the waste slagheap surface, the concentrations of Cu were higher than those of Ni. This means that in the first two mediums, Cu and Ni mainly originated from the tailings, while in the latter two mediums, Cu and Ni mainly came from the atmospheric deposition of airborne particles of the smelting. Cr and Zn were mainly in residual fraction, Cu was mainly in oxidizable and residual fraction.

结果表明：不同区域环境中重金属呈现不同程度累积，其中以Cu、Ni最为显著，含量由高到低依次为尾矿坝排污沟＞尾矿坝＞废渣堆＞农田土壤；尾矿砂和沉积物中重金属分布以Ni含量显著高于Cu含量为特征；而农田土壤和风化物及降尘中重金属分布以Cu含量高于Ni含量为特征，前者Cu、Ni主要来源于尾矿，后者与冶炼烟尘排放有很大关系；样品中除Cr、Zn以残渣态为主外，Cu、Ni、Pb化学形态分布有较大差异，Cu以可氧化态和残渣态为主，Ni以可还原态为主，其次为弱酸提取态，Pb以可还原态为主，其次为残渣态。

Magnesium oxychloride cement was used in the sludge stabilization experiments as a new type stability agent in this paper.

Digestion, alkali-stabilization, composting, irradiation, Pasteurism, and perfection of laws and regulations for stacking and application of sewage sludge are main measures that can be used to abate the pathogenic risks on environment and health.

对污泥的消化、性稳定、沤、射处理和巴氏灭菌，以及完善污泥土地堆放或土地施用的法律法规等是削减污泥中病原物的环境和健康风险的主要措施。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
