一种输出设备,将数据以二维图形表示方式直接在可移动的介质上产生硬拷贝记录。 An output unit that directly produces a hard copy record of data on a removable medium, in the form of a two-dimensional graphic representation.
正方形是二维的(平面的),而正六面体则是三维的(立体的)。 A square is two-dimensional and a cube is three-dimensional.
二维的只有二维的,尤指长度和宽度 Having only two dimensions, especially length and width.
