Neutrons in the slow and moderate speed ranges can produce ionization indirectly in other ways . 慢中子和中能中子可以通过其它方式产生间接电离作用。
Indirect ionization by neutrons can also result from fission of plutonium or uranium isotopes . 通过使钚或铀同位素裂变，中于也能产生间接的电离作用。
When the star becomes hot enough, it ionizes its surrounding gas from which the dust has been expelled . 当恒星变得足够热的时候，它将四周的气体电离，气体中的尘埃被赶走。
in the case of carbonic acid, the ionization constant of is much smallar than the for acetic acid. 至于碳酸，电离常数为比醋酸的电离常数小的多。
Below 60km, ionization is not due to the sun's ultraviolet and x radiation primarily, but to cosmic radiation . 在60公里以下，电离主要不是由于太阳紫外线和X辐射，而是由于宇宙辐射引起的。
Neutrons, being electrically neutral particles, do not produce ionization or excitation directly in their passage through matter . 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。
Inelastic collisions among photoelectrons rapidly distribute their initially gained energy throughout the region of ionized gas . 光电子之间的非弹性碰撞使它们原来获得的能量在整个电离气体中迅速分配。
When a massive proto-star approaches the main sequence, its surface temperature is low and it can not ionize the ambient gas . 当一个大质量原星接近主星序时，它的表面温度是低的，因而不能电离周围的气体。
