| atmospheric composition The chemical abundance in the earth's atmosphere of its constituents including nitrogen, oxygen, argon, carbon dioxide, water vapour, ozone, neon, helium, krypton, methane, hydrogen and nitrous oxide | 大气组成 (大气成分中的化学成分，包括氮，氧气，二氧化碳，氦，氩，氪，氙，以及水蒸气，甲烷，氢气，臭氧，氮氧化物。) |
| chemical composition The nature and proportions of the elements comprising a chemical compound | 化学成分 (化合物的元素组成的性质和比例。) |
| colour composition A remote-sensing term referring to the process of assigning different colours to different spectral bands. The colour picture formed by this process is called a "colour composite" (a colour image produced through optical combination of multiband images by projection through filters) and is produced by assigning a colour to an image of the Earth's surface recorded in a particular waveband. For a Landsat colour composite, the green waveband is coloured blue, the red waveband is coloured green and the infrared waveband is coloured red. This produces an image closely approximating a false colour photograph. Colour composite images are easier to interpret than separate images recording different wavebands. US national experimental crop inventories are based upon visual interpretation of Landsat colour composites | 集群现象 (遥感术语，指的是对不同的可见光带分配不同颜色的过程。在此过程中形成的色彩叫做"复合色"(一种色彩，采用过滤投射对多波段图像进行光学结合)，并且由为地球表面的图像记录制定色彩而形成。对于陆地卫星彩色合成，绿色波段是蓝色，红色波段是绿色，红外波段是红色。这将产生一个非常近似假彩照的图片。彩色复合图像比记录不同波长的单独图像更容易被理解。US国家实验作物资源目录是根据对陆地卫星色彩组成的视觉转换。) |
| composition of population The constituent groupings and proportions of the total inhabitants of a given nation, area, region or city, as seen from various perspectives | 人口组成 (在给定国家、区域、地区或城市等,不同空间尺度下的总居民组成群落和比例。) |
| fuel composition | 燃料组成 (成分) |
| fuel composition | 燃料成分 |
| waste composition The component material types, by percentage or weight, emanating from any source | 废料组成 (从任何来源产生的废料中各种组成成分的百分比或重量。) |
