所以，以iPhone 8 (8, 7, 6S, 6)为例，其显示分辨率是750 x 1334 px ，如果设计师以显示分辨率的尺寸（转换率为@2x）做设计，而开发员需要转换率为@1x、@2x和@3x三种尺寸，那么设计师就需要先导出@1x的设计图，然后再切出@3x的图，这样就比较麻烦些。

维特定理建立了二次方程式 x_1, x_2 x1,x2 的根与系数 a, b, c a,b,c 之间的简单代数关系 (维特公式)。 利用这些公式,如果已知系数就可以求根,如果已知根就可以求系数。 令 x^2 x2 为 y \ (y \ge 0) y (y ≥ 0),就变成了一个二次方程式,可以求出它的两个根 y_1, y_2 y1,y2。 二次次方程式的根可通过如下方式求出: q = \frac {2b^3} {27a^3} - \frac {bc} {3a^2} + \frac {d} {a} = \frac {2b^3 - 9abc + 27a^2d} {27a^3} q = 27a32b3 − 3a2bc + ad = 27a32b3−9abc+27a2d.
