摘要
综述了近年来空气负离子的研究进展,主要从空气离子的评价标准、空气负离子的时间变化、空气负离子的空间变化和空气负离子的保健功能4个方面介绍了空气负离子的研究成果。空气负离子浓度夏秋季节最高,冬春季节较低;早晨和下午各有一个峰值,中午较低;中海拔地区和近水区域空气负离子浓度较高;空气负离子具有促进睡眠,预防疾病等多种功效。
The research of negative air ions in recent years, including evaluation criteria of negative air ions, temporal changes of negative air ions,spatial changes of negative air ions and health effects of negative air ions were reviewed in this paper. The concentrations of negative air ions is higher in Summer and Autumn than in Winter and Springs concentrations of negative air ions have two peaks in morning and dusk,and midday is lower ; negative air ions in middle elevation area and water side are higher than others; negative air ions can also promote sleep and prevent disease.
