空气负离子对人类健康有良好的影响 ,被誉为“空气维生素” ,并被作为衡量空气质量的重要指标而倍受学者的关注。为此我们于 1999年 8月对东北不同地区空气离子浓度和微气候状况进行了综合调查 ,现报道如下。仪器和方法 采用福建产ＤＹＬ - 1Ａ型大气离子测定仪测定迁移离子
Air negative ions have a good impact on human health, known as the “air vitamin”, and as an important indicator of air quality and much scholars attention. To this end, we conducted a comprehensive survey of air ion concentrations and microclimate conditions in different regions of Northeast China in August 1999, and are reported below. Instruments and Methods The migration of ions was determined by the DYL - 1A atmospheric ion detector manufactured by Fujian Province
