核, 核心集。

A set of pairs of a mapping's domain which are mapped to the same value.

Examples :

"In Ms. Johnson's math class, the kernels of the function "find the remainder after dividing by 5" consisted of all numbers that leave the same remainder (like 2, 7, 12, etc., all grouped together because they leave a remainder of 2). "

在约翰逊老师的数学课上，函数“求除以5的余数”的核心集指的是所有余数相同的数字（例如，2、7、12等等，因为它们都余2，所以被归为一组）。

在化学课上，教授解释说，原子实（原子核和内层电子）带正电荷，并且很大程度上决定了原子的质量，而价电子则决定了它如何与其他原子结合。
