noun

光谱，谱线。

Specifically, a range of colours representing light (electromagnetic radiation) of contiguous frequencies; hence electromagnetic spectrum, visible spectrum, ultraviolet spectrum, etc.

Examples :

"When sunlight passes through a prism, it separates into beautiful spectra of red, orange, yellow, green, blue, indigo, and violet. "
当阳光穿过棱镜时，会分解成绚丽的光谱，呈现出红、橙、黄、绿、蓝、靛、紫等颜色。

noun

谱，频谱。

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.

Examples :

"The spectra of the teacher's grading system showed that some students struggled with a particular type of math problem. "
老师评分系统的频谱显示，一些学生在特定类型的数学问题上遇到了困难。(Lǎoshī píngfēn xìtǒng de pǔ xiǎnshì, yīxiē xuésheng zài tèdìng lèixíng de shùxué wèntí shàng yùdào le kùnnan.)

noun

素谱，谱。

(abstract algebra) The set, denoted Spec(R), of all prime ideals of a given ring R, commonly augmented with a Zariski topology and considered as a topological space.

Examples :

"Let's try this: "Mathematicians studying the abstract properties of rings might examine their spectra to understand their fundamental structure." "
让我们试试这个：研究环的抽象性质的数学家可能会研究环的素谱，以了解它们的基本结构。
