we wish to make triples (x, y, z)from the integers{1, 2, …, (n+1)}. 我們要從整數集1、2、…(n1)中取三數組(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軸的天線,對y軸正下方的觀察者不發送任何光波
For simplicity, we assume e to be in the x direction and to vary sinusoidally in the y direction . 為簡單起見,我們假定E在X方向上,并在Y方向上正弦式地變化。
The regression process contains the likelihood of the future values of the dependent variable y being in error . 在回歸分析程序中,可能使未來的應變量y值產生了誤差。
Let us find the general relation between the pressure p at any point in a fluid and the elevation of the point y . 我們來求流體中任一點的壓力P與該點高度Y的一般關系。
is the eigenvector corresponding to , and y(t)= is the associated eigenfunction. 即為對應于的本征矢量,而y(t)為相應的本征矢量。
Our differential equation will involve some sort of relation between an independent variable x and dependent variable y . 我們的微分方程將包含一個自變量x,一個因變量y。
The essence of the problem is the development of a relationship between t and u over the range of y of interest . 問題的要害在于要推導出在整個感興趣的Y范圍內的T與U之間的關系。
The probability of finding the particle in the volume element at point(x.y.z. )with edges dx. dy. dz is as follows . 在點(xyz)具有邊dx,dy,dz的體積元內找粒子的幾率如下。
Depending upon reaction conditions, the product may be a polyketone formed b y addition polymerization of the ketene double bond . 隨著反應條件的不同,產物可以是由烯酮的雙鍵加成聚合得到的聚酮。
