With the progress of science and technology and the improvement of people's awareness of environmental protection, air ions in the study has drawn increasing attention.
随着科技进步和人们环保意识的提高,空气离子的研究越来越引起人们的广泛关注,空气离子按其粒径大小可分为大离子、中离子、小离子,按其带电性可分为正离子和负离子,空气负离子被誉为“空气维生素”、“营养素”、“环境警察”等,是衡量空气环境的重要指标,本文研究了自2006年8月至2007年1月半年时间内,空气离子在不同天气条件下的变化规律,积累了较为丰富的实测资料。
