先理解核心含义,再看它在真实句子里的用法。
荧光;荧光性
light emitted when a substance absorbs radiation of a different, often invisible, wavelength
The fluorescence of the mineral is caused by impurities.
这种矿物的荧光是由杂质引起的。
材料在吸收辐射或亚原子粒子的激发下发出光(或其他电磁辐射)的现象。
The emission of light (or other electromagnetic radiation) by a material when stimulated by the absorption of radiation or of a subatomic particle.
在吸收其他(不可见)波长的辐射时发出的光。
light emitted during absorption of radiation of some other (invisible) wavelength
如此发出的光。
The light so emitted.
The mineral glowed with a bright green fluorescence under the ultraviolet lamp.
这种矿物在紫外线灯下发出明亮的绿色荧光。
Scientists use fluorescence to detect proteins in a cell.
科学家利用荧光来检测细胞中的蛋白质。
The microscope image revealed the fluorescence of the stained bacteria.
显微镜图像显示了染色细菌发出的荧光。
the fluorescence of 后接产生荧光的物质或物体,用于说明荧光来源。
The fluorescence of the mineral is caused by impurities.
这种矿物的荧光是由杂质引起的。
from 强调荧光发射的来源,常用于科学测量场景。
We measured fluorescence from the quantum dots.
我们测量了来自量子点的荧光。
fluorescence 可直接用作定语修饰名词,构成复合名词,如 fluorescence microscope、fluorescence spectroscopy。
The lab uses a fluorescence microscope.
实验室使用荧光显微镜。
Not this
The fluorescence light is very bright.
Use this
The fluorescent light is very bright.
fluorescence 是名词,意为“荧光”,不能放在名词 light 前作定语;修饰名词要用形容词 fluorescent。中文“荧光灯”直译容易把名词“荧光”直接搬进英文,但英语中表示“荧光的灯”应用 fluorescent light。
Not this
Measure the fluorescent intensity of the sample.
Use this
Measure the fluorescence intensity of the sample.
在科学术语中,“荧光强度”的固定搭配是 fluorescence intensity,用名词 fluorescence 作定语修饰 intensity;若改用形容词 fluorescent,语义会变成“荧光的强度”,不符合该术语的规范用法。
Not this
The mineral fluorescences under ultraviolet light.
Use this
The mineral fluoresces under ultraviolet light.
fluorescences 是名词 fluorescence 的复数形式,不能当作动词的第三人称单数使用;表示“发出荧光”应用动词 fluoresce,其第三人称单数是 fluoresces。

荧光显微术
Fluorescence microscopy lets researchers observe specific structures inside living cells.
荧光显微术让研究人员能够观察活细胞内的特定结构。
荧光光谱法
Fluorescence spectroscopy can reveal changes in the molecular environment of a sample.
荧光光谱法可以揭示样品分子环境的变化。
荧光原位杂交
Fluorescence in situ hybridization is used to locate specific genes on chromosomes.
荧光原位杂交用于在染色体上定位特定基因。
荧光寿命
The fluorescence lifetime of the probe was measured under different conditions.
在不同条件下测量了该探针的荧光寿命。
荧光猝灭
Fluorescence quenching can be used to study how molecules interact with each other.
荧光猝灭可用于研究分子如何相互作用。

荧光(fluorescence)里藏着“flu”和“rescence”,联想紫外线一照,荧光物质就发出亮光。
语域:formal 常见场景:科研论文、化学/物理教材、技术文档 fluorescence 是比较正式的科技词汇,通常出现在学术文章、教科书或技术说明中,日常生活口语里比较少见。
这些词都以 -escence 结尾,重读音节为 /ˈrɛsəns/,与 fluorescence /ˌfluəˈrɛsəns/ 押韵。注意 fluorescent /ˌflʊəˈrɛsənt/ 拼写相近但结尾是 /ənt/,不押韵;fluoresce /ˌflʊəˈrɛs/ 也不押韵。
