图典词表

英文/音标中文/解释

1	polar-orbiting satellite	极地轨道卫星
	Satellite that travels in a polar orbit around the globe 14 times per day; this allows it to cover the entire surface of the globe, due to the Earth’s rotation. 一种每天绕地球14次的极地轨道运行的卫星，由于地球自转，它可以覆盖地球的整个表面。
2	solar array drive	太阳能阵列驱动器

3	radiometer [ˌreɪdɪ’ɒmɪtə]	辐射计;放射计
	Instrument designed to measure electromagnetic radiation energy at a given frequency. 测量给定频率下电磁辐射能量的仪器。
4	thermal louver	热角鳞板
	Adjustable mechanical component designed to modify thermal flux. 可调节的机械部件，用于调节热通量。
5	reaction engine assembly	反作用发动机总成
	Micromotor that makes it possible to direct a satellite to the desired position. 使卫星能够定向到所需位置的微马达。
6	ultraviolet spectrometer	紫外光谱仪; 紫外线分光计
	Instrument that monitors ozone levels in the Earth’s atmosphere. 监测地球大气臭氧水平的仪器。
7	S-band antenna	S波段天线
	Antenna that enables a satellite to transmit the data it collects to the terrestrial station. 使卫星能够把它收集的数据传送到地面站的天线。
8	Earth radiation sensor	地球辐射传感器
	Radiometer that measures solar radiation and reflection in the Earth’s atmosphere. 测量太阳辐射和地球大气反射的辐射计。
9	Earth radiation scanner	地球辐射扫描仪
	Radiometer that analyzes a region of the globe by means of repeated scans. 通过重复扫描分析地球某一区域的辐射计。
10	microwave scanner	微波扫描仪
	Instrument that produces an image of an observed area even in cloudy conditions since microwave frequencies pass through clouds. 由于微波频率通过云层，即使在多云的情况下也能产生观测区域图像的仪器。
11	infrared sounder	红外探测仪
	Instrument that measures thermal energy in clouds and on the Earth’s surface with a view to capturing nighttime images of weather systems and cloud cover. 测量云和地球表面热能的仪器，目的是捕捉夜间天气系统和云层的图像。
12	instrument platform	仪表台

13	search-and-rescue antennas	搜救天线
	Device that picks up distress signals emitted by ships or aircraft and makes it possible to determine their location. 接收船只或飞机发出的求救信号并能确定其位置的装置。
14	battery modules	电池模块
