当需要时，他们所用的旋转力，使电力（传统方式） ，并降低其速度提取它的能量。

When needed, they used that rotational force to make electricity (the classic way), and decrease its speed, by extracting energy from it.

通过在针状物上施加电压，一个从液体提取离子并加速他们到一个非常高的速度然后强迫它们飞离的电场就被创造出来。

By applying voltage to the needles, an electric field is created that extracts the ions from the liquid, accelerates them at very high speeds and forces them to fly away.

And there are various forces that play in the nucleus that will dictate when this will be stable and when it won't be.They isolated it, but it decays very quickly on the order of microseconds Lifetime on the order of microseconds.

在原子核中有很多种力,都会产生作用，当条件是稳定的,还有当它不是的时候，它们提取出来，但是它会以微秒的速度衰变,生命只有几微秒长。
