核心释义
an ordered array of the components of an emission or wave
- 1.
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.
- 2.
发射或波成分的有序排列
an ordered array of the components of an emission or wave
- 3.
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.
- 4.
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
- 5.

- 6.

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
- 11.
闭眼后仍残留的所见影像。
The image of something seen that persists after the eyes are closed.
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。

语法说明Grammar Note
复数形式为spectra
发音与拼写Pronunciation & Spelling
No common word shares the exact /trəm/ ending sound of 'spectrum'. Words like 'forum' (/ˈfɔːrəm/) have a similar /rəm/ ending but with a different stressed vowel and sound. Note that 'spectrum' is pronounced /spɛktrəm/, so the 'trum' is unstressed.
