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）。
Hence, the antenna along the y-axis does not send any light to the observer directly below it . 因此，沿y轴的天线，对y轴正下方的观察者不发送任何光波
For simplicity, we assume e to be in the x direction and to vary sinusoidally in the y direction . 为简单起见，我们假定E在X方向上，并在Y方向上正弦式地变化。
The regression process contains the likelihood of the future values of the dependent variable y being in error . 在回归分析程序中，可能使未来的应变量y值产生了误差。
Let us find the general relation between the pressure p at any point in a fluid and the elevation of the point y . 我们来求流体中任一点的压力P与该点高度Y的一般关系。
is the eigenvector corresponding to , and y(t)= is the associated eigenfunction. 即为对应于的本征矢量，而y（t）为相应的本征矢量。
Our differential equation will involve some sort of relation between an independent variable x and dependent variable y . 我们的微分方程将包含一个自变量x，一个因变量y。
The essence of the problem is the development of a relationship between t and u over the range of y of interest . 问题的要害在于要推导出在整个感兴趣的Y范围内的T与U之间的关系。
The probability of finding the particle in the volume element at point(x.y.z. )with edges dx. dy. dz is as follows . 在点（xyz）具有边dx，dy，dz的体积元内找粒子的几率如下。
Depending upon reaction conditions, the product may be a polyketone formed b y addition polymerization of the ketene double bond . 随着反应条件的不同，产物可以是由烯酮的双键加成聚合得到的聚酮。
