We recall the notion of rational number, defined as a quotient of two integers . 我们回想有理数的概念，它定义为两个整数之商。Rr
In each case an integral number of wavelengths fit into the circumference of the loop . 在各种情形下，环的周长都等于波长的整数倍。
Discrete data are expressed in whole numbers: 2 children, 56 trucks, 5 actors . 间断资料用整数表示，如2个孩子，56辆汽车，5名演员等。
It will be much easier to understand if the fractions are rounded up to the whole numbers . 如果把分数调高为整数，那么就更加容易理解了。
we wish to make triples (x, y, z)from the integers｛1, 2, …, (n＋1)｝. 我们要从整数集1、2、…（n1）中取三数组（x，y，z）。
for self-consistency, the sum of all these phase shifts must be a multiple of 2π. 为了自洽起见，这个相移的累加总和必须为2的整数倍。
Call a set of integers fat if each of its elements is at least as large as its cardinality . 称一个整数的集合为饱和的，如果它的每一个元素都至少不小于其基数。
This classification is called the parity of the permutation analogous to the definition of parity of integers . 这种分类叫作置换的奇偶性，类似于整数偶性的定义。
Its frequency is an integral multiple of one-half the classical frequency of revolution of the electron in the bound orbit . 其频率为在束缚轨道上电子旋转的经典频率之半的整数倍。
Neither euler nor lagrange envisioned the rich possibilities which their work on complex integers opened up . 无论Euler或Lagrange都没有预想到他们关于复整数的工作所打开的丰富可能性。
