| 伽马射线环境成像频谱仪 | gamma ray environmental mapping spectrometer |
| 光谱学 | spectroscopy The branch of physics concerned with the production, measurement, and interpretation of electromagnetic spectra arising from either emission or absorption of radiant energy by various substances (物理学的分支，涉及生产，测量和无论从各种物质发射或辐射能量吸收而引起的电磁光谱的解释。) |
| 光谱带 | spectral band Closely grouped bands of lines characteristic of molecular gases of chemical compounds (spectroscopy) (化合物的分子气体的线性特征的密集带(光谱)。) |
| 吸附色谱学 | adsorption chromatography |
| 噪声频谱 | noise spectrum The range of frequencies occurring in the noise emitted by a source (出现在同一来源发出的噪声的频率范围。) |
| 多谱扫描器 | multispectral scanner A remote sensing term referring to a scanning radiometer that simultaneously acquires images in various wavebands at the same time. A multispectral scanner can be carried aboard an aircraft or satellite. The Landsat multispectral scanner records images in four wavebands of visible and near infrared electromagnetic radiation to enable objects with different reflectance properties to be distinguished (一个遥感术语，指扫描辐射计，它能同时获得各种波段的图像。多光谱扫描仪可以安放在飞机或卫星上。在4个可见光和近红外波段的电磁辐射图像中陆地卫星多光谱扫描仪记录，不同对象以反射属性加以区别。) |
| 对流层发射物光谱仪 | tropospheric emission spectrometer |
| 气相色谱法 | gas chromatography A separation technique involving passage of a gaseous moving phase through a column containing a fixed phase; it is used principally as a quantitative analytical technique for volatile compounds (分离技术，将气体物质通过移动相柱；定量分析技术用于分析挥发性化合物。) |
| 色谱层分析 | chromatographic analysis The analysis of chemical substances that are poured into a vertical glass tube containing an adsorbent where the various components of the substance move through the adsorbent at different rates of speed according to their degree of attraction to it, thereby producing bands of color at different levels of the adsorption column (对化学物质的分析，该化学物质被倒到一个垂直的玻璃试管中，玻璃试管中含有吸附剂，根据吸附剂对物质的各种组成成分的吸附能力，组成成分以不同的速率通过吸附剂，因此吸附柱上产生不同层次的颜色带。) |
| 色谱法 | chromatography A method of separating and analyzing mixtures of chemical substances by selective adsorption in a column of powder or on a strip of paper (一个分离和分析化学物质的混合物质的方法，通过选择性的吸附(作用)在一栏的粉末或在一张纸条上。) |
