| 从沉淀室排出的在养殖单元底部积累的固体物质和水的混合物。污水处理中：在大部分液体从污水中被除去后保留下来的泥泞、半固体沉淀物. | sludge |
| 冰水沉积区 | outwash area |
| 土壤沉积 | soil settling Compaction involves the close-packing of the individual grains mainly by the elimination of pore-space and expulsion of entrapped water; this is normally brought about by the weight of the overlying sediments (涉及到个人粮食的紧密包装，主要由消除空隙空间和驱除水质所造成；这通常是由上覆的沉淀物的重力所引起的。) |
| 垃圾沉积 | sinking of waste A manner of waste disposal in which refuse or unwanted material is dumped or submerged beneath the surface of a body of water (一种将垃圾或有害材料倾倒到水体表面的水下方的废物处理方式。) |
| 沉积工业处理, 通过重力或离心作用从液体中分离悬浮在其中的不溶解的固体。 | sedimentation industrial process, The separation of an insoluble solid from a liquid in which it is suspended by settling under the influence of gravity or centrifugation |
| 沉积作用 | deposition The process by which polluting material is precipitated from the atmosphere and accumulates in ecosystems (污染物质从大气中沉降，因而堆积于生态系统的过程。) |
| 沉积学 | sedimentology The scientific study of sedimentary rocks and of the processes by which they were formed; the description, classification, origin, and interpretation of sediments (对沉积岩和它们形成的过程的科学研究；对沉积物的描述、分类、起源和解释。) |
| 沉积物 | sediment Any material transported by water which will ultimately settle to the bottom after the water loses its transporting power (任何被水输送的物质，当水失去了输送力量之后，最后沉到水底。) |
| 沉积物搬运 | sediment transport The movement and carrying- away of sediment by natural agents; especially the conveyance of a stream load by suspension, saltation, solution or traction (通过自然力量移动沉积物；特别是通过溪流的悬浮、跳动、溶解或拖动来搬运。) |
| 沉积物移动 | sediment mobilisation The transport or setting in motion by wind or water of insoluble particulate matter (不能溶解的物质被风或水搬运和放置。) |
| 沉积盆地 | sedimentary basin A geomorphic feature of the earth in which the surface has subsided for a prolonged time, including deep ocean floors, intercontinental rifts and elevated and interior drainage basins (地球的地貌特性，地表通过很长时间的沉降，包括很深的海底、大陆架和升起的以及内陆干涸的盆地。) |
| 沉积盆地 | sedimentation basin A basin in which suspended matter is removed either by quiescent settlement or by continuous flow at high velocity and extended retention time to allow deposition (一个盆地，在那里悬浮物被静态沉降或被连续流体高速移动，经过很长时间使它们沉积下来。) |
| 海洋沉积物 | marine sediment Solid fragmental material, originated from weathering of rocks, that has settled down from a state of suspension in the water (固体断片材料，起源于岩石风化，并由水中的悬浮态沉淀而成。) |
| 自由无影响沉积作用 | unhindered settling |
| 酸沉积 | acid deposition A type of pollution which washes out of the atmosphere as dilute sulphuric and nitric acids. It tends to be a regional rather than a global phenomenon, linked to particular industrial activities and meteorological conditions. It includes rain, more than normally acidic snow, mist, sleet, fog, gas and dry particles. It upsets the balance of nature, disrupting ecosystems, and destroys forests and woodlands, plants and crops; kills aquatic life by altering the chemical balance of lakes and rivers and corrodes building materials and fabrics. The pollutants are caused principally by discharges from power station chimneys of sulphur dioxide and nitrogen oxides released by burning fossil fuels, coal and oil (一种将冲刷大气层后产生硝酸或硫酸污染。酸沉淀往往是地域性而不是全球性的，与某种特定的工业活动或者气象条件相关。酸沉淀包括雨，以及酸性含量较高的酸性雪、雾、冻雨、气体以及干性微粒。它破坏了自然的平衡，破坏生态系统；毁坏了森林、草地、植物以及农作物；改变了江河湖水的化学平衡，进而杀死了水生物；侵蚀了建筑材料和纤维。这种污染主要来源于电厂在燃烧矿物燃料、煤和油时从烟囱排出的二氧化硫和氮氧化物。) |
