从太阳而来的辐射，将尘埃粒子吹离彗发，形成尘埃彗尾；同时，来自太阳的带电粒子将一些彗星气体电离成离子，形成离子彗尾。
Radiation from the sun pushes dust particles away from the coma, forming a dust tail, while charged particles from the sun convert some of the comet's gases into ions, forming an ion tail.
最重要的一点是在电离层的电子和其他带电粒子的密度是波动的。
One of the most important of these is a fluctuation in the density of electrons and other electrically-charged particles in the ionosphere.
中子是中性不带电的粒子，当它通过物体时并不直接产生电离或激发作用。
Neutrons, being electrically neutral particles, do not produce ionization or excitation directly in their passage through matter.
各种金属或金属合成靶材被带电离子撞击，造成金属原子成为自由粒子沉积在上面的聚酯薄膜的表面。
Various metal or metal the material composing a target is collide with by electrified ion is brought about the metal atom becoming the free particle deposition surface in mylar above.
有许多这样的质子和电子还被电离了，所以还有不少这样的被称为离子的带电粒子在飘来荡去。
In many of these the proton and electron have become separated, resulting in free-floating charged particles called ions.
