the spectrum of [something]
The book covers a wide spectrum of topics.
这本书涵盖了广泛的主题范围。
光谱
spectrums — plural of spectrum
范围；连续、无限、一维的集合,可能由极端值界定。；发射或波成分的有序排列；特指由连续频率的光(电磁辐射)所呈现的颜色范围；因此有电磁波谱、可见光谱、紫外光谱等。；相关对象、价值、品质、想法或活动的广泛范围；自闭症谱系。
范围；连续、无限、一维的集合,可能由极端值界定。
A range; a continuous, infinite, one-dimensional set, possibly bounded by extremes.
发射或波成分的有序排列
an ordered array of the components of an emission or wave
特指由连续频率的光(电磁辐射)所呈现的颜色范围；因此有电磁波谱、可见光谱、紫外光谱等。
Specifically, a range of colours representing light (electromagnetic radiation) of contiguous frequencies; hence electromagnetic spectrum, visible spectrum, ultraviolet spectrum, etc.
相关对象、价值、品质、想法或活动的广泛范围
a broad range of related objects or values or qualities or ideas or activities
自闭症谱系。
The autism spectrum.
用于射频通信的一组频率；不一定是连续范围。
A set of frequencies that are used for radio-frequency communication; not necessarily a continuous range.
物质在受到能量(辐射、热、电等)作用时产生的辐射吸收或发射模式。
The pattern of absorption or emission of radiation produced by a substance when subjected to energy (radiation, heat, electricity, etc.).
矩阵的特征值集合。
The set of eigenvalues of a matrix.
对于有界线性算子A,使算子A-λI(其中I为单位算子)没有有界逆的标量值λ的集合；旨在推广线性代数中的含义。
Of a bounded linear operator A, the set of scalar values λ such that the operator A—λI, where I denotes the identity operator, does not have a bounded inverse; intended as a generalisation of the linear algebra sense.
数学中由交换环R构造的抽象对象,记为Spec(R)或SpecR,称为R的谱；在研究此类环时,它提供了一个几何对象,编码了R的许多性质,并在现代几何中用于将代数簇的概念推广为仿射概形。形式上,是配备Zariski拓扑的所有素理想集合,并附加一个称为结构的环层。
An abstract object in mathematics created from a commutative ring R and denoted operatorname Spec(R) or operatorname SpecR and said to be the spectrum of R; useful in the study of such rings for providing a geometric object which encodes many of the properties R, and in modern geometry for generalizing the notion of an algebraic variety to that of an affine scheme. Formally, the set of all prime ideals R equipped with the Zariski topology and augmented with a sheaf of rings called the structure
闭眼后仍残留的所见影像。
The image of something seen that persists after the eyes are closed.
When white light passes through a prism, it spreads into a spectrum of colors.
当白光通过棱镜时，它会分散成彩色的光谱。
用法提示：这里 spectrum 指光经色散后形成的连续色带，是名词。
Astronomers analyze the spectrum of a star to learn what elements it contains.
天文学家分析恒星的光谱，以了解它含有哪些元素。
用法提示：spectrum 在此指天体发出的光按波长排列的谱带。

每种化学元素都有独特的光谱，就像指纹一样。
用法提示：spectrum 表示元素特有的光谱特征。

常用于医学语境，指自闭症谱系。
He was diagnosed as being on the autism spectrum.
他被诊断出自闭症谱系障碍。

该提案得到了各政治派别的支持。
最通用的同义词，适用于大多数语境，强调从一端到另一端的跨度。
侧重多样性，不强调顺序或连续。
带有彰显或展示的意味，常用于令人印象深刻的事物。
强调涵盖全部可能，常用于评价或情感领域，语气较强。
更学术化，强调无间断的连续性，不常用于日常对话。
