另外，还披露了用于制造这种介质的方法，例如倾斜溅射或选择性蚀刻。

Further methods for manufacturing such a medium are described, e. g. inclined sputtering or selective etching.

但是他们所提供的是清晰度和可读性，对比度则乏善可陈：其效果相当灰暗，就像蚀刻素描。

But what they offer in clarity and readability, they lack in contrast: Their look is decidedly gray, like an etch a Sketch.

纳米电子蚀刻素描可以通过施加负电压，对画好的线路进行选择性清除。 他们的成果刊登在去年出版的《科学》杂志上。

Not so with the nanoelectric Etch A Sketch, which can selectively erase the conducting lines it creates by applying negative voltage.
