电场对空气分子浓度分布的影响

The effect of electric field on the distribution of atmospheric molecular concentration

被极化的空气分子受到电场的作用具有向场强大的地方运动的趋势,另一方面,由于分子热运动的作用将破坏这种趋势,最终结果导致场强大的地方分子浓度高,场强弱的地方分子浓度低.但高压输电线附近的空气分子浓度比别处高吗?本文由玻尔兹曼分布律推导出电场中气体分子浓度随场强变化的公式,发现电场对空气分子浓度分布的影响非常微弱.

Polarized atmospheric molecules always tend to move where the electric field intensity is high. On the other hand, their random movements oppose this tendency. As a result, the stronger is the field, the thicker is the molecular concentration. Is it thicker, the atmospheric molecular distribution near a high voltage transmission line than somewhere else？ An equation of atmospheric molecular concentration in electric field is deduced from Boltzmann distribution. It is found out that the influence of electric field on atmospheric molecular concentration is very little.
