In this way, label of X-axis and Y-axis will be represented using localized business name, instead of developer-oriented object name.

这种方式下，x坐标轴和y坐标轴的标签将会使用本地化的业务名称来表示，而不是用面向开发人员的对象名称来表示。

So "y" is a sort of a light-weight object, rather than a copy of a range of elements.

这里“y”是一个轻量级的对象，而不是“x”数组中元素的拷贝。

youdao

Consider a set of observations (also called features, attributes, variables or measurements) for each sample of an object or event with known class y.

设观测向量x(也被称作特征、属性、变量、测量值等)对于对象或事件的每一个采样的所属类y都是已知的。

youdao

Consequently, for this object the position y, at any time t is known to be 15+10t-5t^.

因此,对这个物体来说,在任意时刻的位移y,就应该为15+10t-5t^
