原型机

Full - scale prototypes may be " cleaned up ".

全尺寸原型机可以得到 “ 校验 ”。

Moreover, prototypes can be built directly from the computer models.

而且， 利用计算机计算出的模型可以造出原型机。

But the picture phone has been mostly a perpetual prototype to date.

但迄今为止，大多数的可视电话长期以来一直停留在原型机的水平。

A prototype could be built and flying in less than two years.

在两年之内一架原型机就会被建造和试飞。
