| atmospheric layering Any one of a number of strata or layers of the earth's atmosphere; temperature distribution is the most common criterion used for denoting the various shell. Also known as atmospheric shell; atmospheric region | 大气分层 (大气中的任意一层，温度分布是最常见的标准，用来指代不同的层次。也称作大气壳，大气区域。) |
| boundary layer | 边〔临〕界层 |
| boundary layer | 附〔界〕面层 |
| boundary layer The layer of fluid adjacent to a physical boundary in which the fluid motion is significantly affected by the boundary and has a mean velocity less than the free stream value | 边界层 (与物理边界相邻的流体层，其中边界对流体运动有重大影响，具有平均流速低于自由流的值。) |
| boundary layer climate | 界面层气候 |
| inversion layer The atmosphere layer through which an inversion occurs | 逆温层 (通过其发生反演的大气层。) |
| inversion layer | 逆转〔逆温〕层 |
| ozone layer The general stratum of the upper atmosphere in which there is an appreciable ozone concentration and in which ozone plays an important part in the radiative balance of the atmosphere | 臭氧层 (在大气层的上层，臭氧浓度明显增强，其中臭氧对于保证大气辐射的平衡起到了重要的作用。) |
| ozone layer depletion The fragile shield of ozone is been damaged by chemicals released on earth. The main chemicals that are depleting stratospheric ozone are chlorofluorocarbons which are used in refrigerators, aerosols, and as cleaners in many industries, and halons, which are used in fire extinguishers. The damage is caused when these chemicals release highly reactive forms of chlorine and bromine. Over the past 30 years ozone levels over parts of Antarctica have dropped by almost 40% during some months and a "hole" in ozone concentrations is clearly visible in satellite observations | 臭氧层损耗 (脆弱的臭氧保护层被地球上释放的化学物质所破坏。破坏大气层臭氧的主要化学物质是在冰箱和气雾剂中使用的氯氟烃，包括清洁行业，以及使用灭火器。这些化学物质释放的氯和溴在高活性状态下，会对臭氧造成损害。在过去30年里，南极地区的臭氧水平已经下降了近40％，在某几个月甚至会出现卫星可观测到的"臭氧空洞"。) |
| soil layer Distinctive successive layers of soil produced by internal redistribution processes. Conventionally the layers have been divided into A, B and C horizons. The A horizon is the upper layer, containing humus and is leached and/or eluviated of many minerals. The B horizon forms a zone of deposition and is enriched with clay minerals and iron/aluminium oxides from the A layer. The C layer is the parent material for the present soil and may be partially weathered rock, transported glacial or alluvial material or an earlier soil | 土层 (由内部的再分配过程所产生的独特的连续层土壤。传统的土壤层被分为A，B，C三层。A层是最上层，含有腐殖质，被浸出和/或多种矿物质淋溶。B层形成沉淀区，富含粘土矿物和来自A层的铁/铝氧化物。C层是当前土壤的母质，部分可能是风化岩，运输冰川或冲积土材料或者是更早的土壤。) |
