As such, it governs-among other things-the energy levels of an atom formed from negatively charged electrons and a positive nucleus.

就此而论，它控制由带负电荷的电子与正电荷原子核的形成的原子能级。

That means it lacks sufficient energy, like x-rays and gamma rays, to remove an electron from an atom or a molecule to make a charged particle that can damage DNA and biomolecules.

也就是说，微波辐射与X射线和伽玛射线不同，是不具有足够的能量的，从而不会使原子或分子失去电子而变成带电粒子，造成DNA及其它生命分子的损坏。

The remainder of the atom from which one or more electrons are removed must be positively charged.

如果从原子中移走一个或多个电子，则该原子的其余部分必定带正电。

One effect of the beam is to polarise the cloud of electrons surrounding each rubidium nucleus, meaning that part of the atom becomes a negatively charged pole, and part a positively charged pole.

Although the probe would carry no cameras in the classic sense, its onboard instruments would include a low-energy charged particle experiment, a magnetometer, a cosmic ray detector, and an energetic neutral atom detector.
