Dr Stachewicz and Mr Ura propose instead to use a technique called electrospinning. This also involves a hollow needle.

斯塔切薇兹博士和尤拉先生提议使用一种叫做静电纺丝的技术，这也涉及空心针。

One consequence of electrospinning is that the voltage attracting the thread from needle to drum also attracts or repels, according to their polarity, the charges on the molecules within.

静电纺丝的一个结果是，根据针管内部分子的极性，将线从针管吸引到滚筒的电压也会吸引或排斥其中的电荷。

Dr Stachewicz theorised that careful manufacture via a process known as electrospinning could lend the sheet a slight electrical charge that would prove attractive to water droplets in fog.

斯塔切维奇博士的理论是，通过一种名为静电纺丝的工艺精心制造，可以使薄片带上轻微的电荷，从而吸引雾中的水滴。
