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。
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.
极光是由地球大气上层的气体分子与来自太阳的高能带电粒子相互作用产生的。
Aurorae are caused by the interaction between energetic charged particles from the sun and gas molecules in the upper atmosphere of the Earth.
极光这一现象是由“太阳风”所造成的。“太阳风”是太阳发射的带电原子内粒子流，它和大气层中的分子相互发生作用就引起了极光。
The phenomena are caused by the "Solar Wind" - streams of electrically charged sub-atomic particles emitted by the Sun - interacting with molecules in the atmosphere.
而当它们达到地球的表面时，它们就与空气反应——把空气的分子转变成为称作为离子的带电粒子。
And when they arrive at the Earth's surface they react with the air - converting air molecules into charged particles known as ions.
