spectrometer
质谱仪
核心释义
此处按英文释义指质谱仪(mass spectrometer),而非泛指分光计。
a spectroscope that produces a mass spectrum by deflecting ions through a thin slit and measuring the ion current with an electrometer
- 1.
测量化学物质对光吸收的光学仪器;通常绘制吸收对波长或频率的图谱,所得图形用于识别存在的物质及其内部结构。
An optical instrument for measuring the absorption of light by chemical substances; typically it will plot a graph of absorption versus wavelength or frequency, and the patterns produced are used to identify the substances present, and their internal structure.
- 2.
通过将离子偏转至狭缝并用电位计测量离子电流以获得质谱的质谱仪
spectroscope for obtaining a mass spectrum by deflecting ions into a thin slit and measuring the ion current with an electrometer
测量化学物质对光吸收的光学仪器;通常绘制吸收对波长或频率的图谱,所得图形用于识别存在的物质及其内部结构。;通过将离子偏转至狭缝并用电位计测量离子电流以获得质谱的质谱仪;分光计;谱仪;[化] 分光计; 分光仪
用法In use
The technician adjusted the spectrometer until the ion current became stable.
用法提示:spectrometer 是名词(单数),作 adjusted 的宾语,指通过偏转离子测量质谱的仪器。

记忆技巧Memory Tip
spectr(光谱)+ meter(测量):把光按波长拆开并测量的仪器,就是分光计。
语境与语域Context & Register
语域:formal 常见场景:scientific papers、laboratory reports、instrument manuals spectrometer 是科学仪器的专业名称,通常出现在学术或技术性语境,如论文、实验报告和仪器说明书中,而非日常口语。
发音与拼写Pronunciation & Spelling
这些词与 spectrometer 押韵:thermometer, barometer, speedometer, odometer(重读元音为 /ɑ/,结尾为 /mətɚ/)。perimeter 和 diameter 虽也以 -meter 结尾,但重读元音不同(分别为 /ɪ/ 和 /æ/),是形近词而非押韵词。
