| 欧洲共同体关于现有化学品的规定 | EC regulation on existing chemicals Regulation designed to identify and control of risks deriving from existing chemicals. According to this program the main goal is the collection of basic information about existing chemicals including their uses and characteristics, environmental fate and pathways, toxicity and ecotoxicity (规定旨在确定和控制现有化学品所产生的风险。根据这一方案,主要目标是对现有化学品的基本信息进行收集，包括其用途和特点，环境归宿和途径，毒性和生态毒性。) |

| 集群现象 | 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 (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。) |
