| 海陆运动 地壳的缓慢升降运动 ？？ | bradyseism A long-continued, extremely slow vertical instability of the crust, as in the volcanic district west of Naples, Italy, where the Phlegraean bradyseism has involved up-and-down movements between 6 m below sea level and 6 m above over a period of more than 2.000 years (地壳的长期持续的、极其缓慢的垂直不稳定性，如在那不勒斯、意大利火山区西部，在超过2000年的时间里，Phlegraean海陆运动涉及了海拔6m以上和6m以下的升降运动。) |
| 淤泥沉降 | settling of sludge |
| 生物降解 | biodegradability The extent to which a substance can be decomposed - or rotted - by bacteria and fungi. Implies that residues from degradation are nontoxic. One of the most misleading claims in business, because shoppers often assume a biodegradable product to be harmless. Some harmful compounds take much longer to degrade than others and the product can harm the environment while it is rotting. Biodegradation may also be incomplete, sometimes leaving residues in the environment which are more harmful than the original substance. Accumulation in the environment of nonbiodegradable (or poorly biodegradable) substances, such as some biocides, can cause serious problems (物质被细菌和真菌分解或腐烂的程度。暗示降解的残留物的是无毒的。最有误导性的宣称之一就是从购买者经常假设生物降解产品无害。一些有害的复合需要比其他物质长得多的时间降解，而且在腐烂过程中生成的产品会破坏环境。生物降解可能也不完整，有时离开余数在环境——比原更更有害物质，有时会在环境中残留比原物质更加有害的物质。非生物降解(或不善生物降解的)物质在环境中的积累，例如一些杀菌剂，能引起严重问题。) |
| 生物降解 | biodegradation Breaking down of a substance by microorganisms (在微生物作用下分解物质。) |

| 降噪 | noise reduction The reduction in the sound pressure level of a noise, or the attenuation of unwanted sound by any means (以任何方式降低噪音的声压水平或者衰减有害的声音。) |
| 降解 | degradation A type of organic chemical reaction in which a compound is converted into a simpler compound in stages (逐步将一种化合物转换成较简单化合物的有机化学反应。) |
| 降雨侵蚀作用 | rainfall erosion |
| 降雨截获量 | rainfall acceptance |
| 非生物降解的污染物 | non-biodegradable pollutant An organic compound, usually synthetic, that is not decomposed or mineralized by microorganisms or other biological processes (一种有机化合物，通常是合成的，即不分解或由微生物或其它生物过程矿化。) |
